Project Debug | General Engineer | Singapore (HYBRID) | Full-time | debug.com

Project Debug raises, sorts by sex, and releases millions of (non-biting) male mosquitoes in Singapore to reduce the local mosquito population and prevent the spread of dengue and other mosquito-borne illnesses. Our trial in Fresno, CA showed a 95% reduction in female mosquitoes during the seasonal peak.

Our engineering team is pretty small and we need a solid generalist engineer who is interested in becoming a domain expert in our factory, where we do automated rearing and sex sorting. If you run a homelab, have tinkered with Arduino, and can prompt/write some Python, we can teach you everything you need to know about our stack (Go, Python, React, Kubernetes, Tensorflow).

Reach out to katejm@debugproject.com and please mention HN in your email.

I am surely sending you an email. I live in a small village (eastern Himalayas, India) after giving up on city life, run a piggery and chicken farm along with ~ 6 hours of software work.

I am intrigued by products like these which gives "hands-on" a new meaning. Being a new farmer-engineer, this is the kind of work I would love to do.

you have a good internet there? i know starlink hasn't launched here yet

We have Airtel and Jio airfiber. Jio is with Mimosa c6x antenna and it's great.

That's absolutely awesome!

Cool project and great domain!

I can't switch jobs rn, but this is absolutely fascinating

this is sterile technique. males mate females causing eggs to not hatch thus reducing population

Awesome project

I mean this is pretty amazing.

MONUMENTAL | https://www.monumental.co/ | Amsterdam, The Netherlands | Full Time | Onsite

We make robots that autonomously construct buildings. We are currently developing and manufacturing our autonomous bricklaying system in the beautiful centre of Amsterdam. And our robots are already earning real revenue operating on construction sites all over the Netherlands.

We're looking for experienced software engineers for many roles. You can help us solve problems like:

- Data sync and analytics queries across a fleet of robots (that can be offline for hours at a time)

- Modelling buildings in code and finding the right UI for operators to edit them

- Designing systems for robots to drive safely and fully autonomously around a building site

Check out the progress we've already made on Atrium, our operating system for robotics: https://www.monumental.co/atrium

We're rapidly scaling up operations and we need experienced engineers who can build the systems that manage all of that complexity. If you think that 'full-stack' could reasonably mean debugging firmware, mixing buckets of mortar _and_ writing React components, we are looking for you. Robotics experience not required!

https://www.monumental.co/jobs

This seems right down our alley. Our team is currently working on several AI and robotics projects, including some extremely custom robotics ones.

We would love to take this up.

Is this role open to non-EU citizens as well?

Yes

This is very exciting to me

I'd love to apply but it's only open to US workers, think about changing REMOTE to REMOTE (US)

Ah, thank you for this suggestion! Sorry about that.

As an engineer in Canada, I'm quite frustrated by US-only when it's a remote job and we have the same time zones and culture. It's so easy to employ Canadians either as a contractor or through a proxy like Rippling. I think it's easier than employing people in the US.

Is there a reason you limit it to the US only?

Form AI | Full-Stack AI Engineer (Contract) | REMOTE (US) / Austin | https://formai.build

Form is an AI fluency/integration startup for executives & their teams. We build AI applications tailored to how clients work, and need an engineer to do the building.

A typical engagement starts with a client describing a workflow eating their week. You scope alongside them, then build something that makes it disappear. Stack is whatever fits: TypeScript and Python, React or Next.js, Claude and other LLM APIs, integrations with the SaaS our clients use (Notion, Slack, Google Workspace). RAG, agents, prompt engineering, and evals when the work calls for them, not for show.

We're looking for someone who has shipped end-to-end as an early engineer somewhere small, has real opinions about LLM applications, and writes readable code. Comfort scoping with clients and communicating in writing is essential, since most of our work happens that way.

1099 fractional, paid monthly. 10-20 hrs/week, $75-150/hour. 40-hour monthly minimum, scaling with client demand. Potential to convert to a full-time role ($150k-$220k) as the practice grows.

Remote, Austin/US-based. To apply: https://formai.build/jobs or email jobs@formai.build.

Deep Core Technology | Founding Engineer | REMOTE (CANADA) | Full Time | Salary: $105,000 - $125,000 CAD + 1% equity

Company: We’re building a geologic modelling software, based on reasoning, to help mining and mineral exploration companies work faster. Our goal is to create a way to enable open-ended, interpretive geologic problem solving to be done programmatically, changing the way to explore for hard rock and critical minerals. Currently in active fundraising.

Role: You are the founding engineer on the team, joining co-founder (Neil, CEO) and myself (Jeff, CTO) as first employee. You’ll have a deep influence over systems and architecture. You will have ownership through the entire stack from the database, through geostatistical backend services, through 3D rendering on the client side.

Work rooted in agentic systems, so an understanding of the internals of things like Claude Code, and a broader understanding of orchestrating agents to complete complex discrete tasks is important.

You:

- Fluent in Typescript, Python, and framework/tooling agnostic (Currently using things like NextJS, Supabase, Cesium)

- Eager to learn about mining domain knowledge around the software.

- Ownership of the codebase, and the systems that support the software (project management, CI/CD, monitoring, etc.)

- Open to doing a yearly month abroad with Neil and I. Last year, it was Oaxaca, Mexico.

Apply: Shoot me an email at jeff@deepcoretech.com with a resume, and a short blurb about yourself. If you include a 1 minute video/Loom, I'd love to see it. Must be eligible to work in Canada without a VISA requirement. We are located in Squamish, BC.

We're hiring a Senior Mobile Engineer to own the frontend of this app. You'll oversee significant parts of the codebase, work closely with a small product and design team, and ship features that put real dollars back in low-income families' pockets.

A good fit:

- You have 3+ years of mobile engineering experience building end to end user solutions

- You have deep React Native experience, ideally having built an app from scratch or meaningfully contributed to a production app

- A track record of leading technical initiatives, mentoring engineers, and driving complex projects from design through execution

Loophole Labs | Senior Systems Engineer | REMOTE (Americas & Europe) | $150k–195k USD + equity | Go, Zig, Rust, C, eBPF, CRIU, Kubernetes

We make Architect: a Kubernetes runtime that hibernates idle pods in place and wakes them in 50ms with TCP connections intact. Five engineers. You'd be the 6th.

If tracing an x86 instruction in the morning and hunting a control-plane race in the afternoon both sound fun, and you insist on measuring rather than guessing, this is the job.

Customers run Architect for workloads where cold starts hurt: real-time voice & video AI agents, long-warming JVM apps, stateful data services that can't be rescheduled cheaply. 1.0 shipped Q1 2026; you'd join mid-way through 2.0. Seed-stage, VC-funded, a few years of runway. Fully distributed across the Americas and Europe.

What you'd work on:

- Hibernation surface: containerd shims and CRUISE, our Zig-native CRIU replacement.

- Control plane: per-node DaemonSet streaming checkpoints; admission controller resizing hibernated pods in place.

- Networking and migration: eBPF/XDP at line rate; cross-node live migration to production; cross-cloud next.

You're a senior generalist. Years across the stack: assembly to frontends, hardware-near, comfortable in x86. Tests ship with the code, decisions get worked out in writing, and you measure rather than guess. Strong in Go; willing to use Zig, Rust, or C.

Bonus: eBPF/XDP, CRIU, Linux kernel internals, containerd, gVisor, live migration, or public writing in kernel/container/eBPF land. Strong systems depth and the willingness to pick up the rest is enough on its own.

Apply: https://loopholelabs.io/careers - we respond within the week (typically a few days).

Spacelift | Remote (Europe) | Full-time | Senior Software Engineer | $80k-$110k+ (can go higher)

We're a VC-funded startup (recently raised $51M Series C) building an infrastructure orchestrator and collaborative management platform for Infrastructure-as-Code – from OpenTofu, Terraform, Terragrunt, CloudFormation, Pulumi, Kubernetes, to Ansible.

On the backend we're using 100% Go with AWS primitives. We're looking for backend developers who like doing DevOps'y stuff sometimes (because in a way it's the spirit of our company), or have experience with the cloud native ecosystem. Ideally you'd have experience working with an IaC tool, i.e. Terraform, Pulumi, Ansible, CloudFormation, Kubernetes, or SaltStack.

Overall we have a deeply technical product, trying to build something customers love to use, and have a lot of happy and satisfied customers. We promise interesting work, the ability to open source parts of the project which don't give us a business advantage, as well as healthy working hours.

If that sounds like fun to you, please apply at https://careers.spacelift.io/jobs/3006934-software-engineer-...

You can find out more about the product we're building at https://spacelift.io and also see our engineering blog for a few technical blog posts of ours: https://spacelift.io/blog/engineering

Stealth Startup | Founding Engineer | NYC (in-person 5x/week) | Full-Time

The mission We’re building a best-in-class multi-modal AI agent product (voice + SMS + email) with the potential to disrupt deeply entrenched software businesses and unify a fragmented industry. We’re a tiny team with real traction pre-product, moving fast, and we care obsessively about craft.

Why this role This is a founding engineering seat: you’ll be an early builder shaping the product, architecture, and quality bar from day one. In the first 3–6 months, the role is highly IC-focused. As we scale (including our first in-person hub/site and new hires), this role has optionality (i.e., growing into a leadership role or staying on the IC track and owning the engineering roadmap) for the right person.

What you’ll do

Build real-time systems for voice (streaming audio, low latency, turn-taking), SMS, and email automation with robust state + memory. Design the foundation: architecture, data model, reliability, observability, deployment, and developer velocity. Set the quality bar: clean code, pragmatic abstractions, testing strategy, “don’t break prod,” and thoughtful product UX. Partner closely with the co-founders on product decisions. You’ll have real influence over what we build and how it feels + how it's designed.

What we’re looking for You should be able to work anywhere in the stack (frontend, backend, infra, integrations) and you know how to make smart tradeoffs.

Strong product sense: you’re obsessive about confusing UI and you want to make workflows feel magical. Systems thinking: you can design for latency, reliability, and iteration speed (especially for real-time voice + agent state). High ownership: you run toward ambiguity, unblock yourself, and care deeply about outcomes. Startup mindset: high-risk/high-reward energy, low ego, high pace.

Bonus points:

Experience with agentic systems: LLM orchestration, tool calling, RAG, evals, prompt/versioning, guardrails. Voice/telephony or streaming experience (WebSockets/WebRTC, audio pipelines, turn detection). Messaging + deliverability experience (SMS workflows, email sending, compliance/opt-in, bounce handling). Familiarity with modern stacks (examples): TypeScript/Node, Python, React/Next.js, Postgres, Redis, queues, Docker, AWS/GCP, observability.

This is very close to what I’m building with JARVIS — a local AI assistant with deterministic command routing, validation boundaries, visible state, and tool execution.

I’m Europe-based, so NYC 5x/week probably makes it hard, but if you’re open to a remote/contract AI systems engineer for agent state, tool calling, workflow execution, or voice/SMS/email automation, I’d be interested.

Doubling | Design Engineer | Chicago or Bay Area preferred | REMOTE (US) also considered | CONTRACT (1099), 10-20 hrs/week

Doubling is building a new mobile product in the health and wellness space. Small founding team, mission-driven, 0-to-1 stage.

We're looking for a Design Engineer to own the mobile UX end-to-end: product design, motion / interaction design, and code contributions where it helps the team move faster. The core of the role is product and motion design; code contributions are valued but not the primary skill we're hiring for.

Stack / tools: Figma, React Native, plus at least one motion or prototyping tool (Rive, Lottie, After Effects, Principle, or Framer).

What we want: 2+ years combined in product design and motion / interaction design, at least one shipped mobile product, a portfolio that demonstrates both UI and motion work, and enough comfort in a frontend codebase to land small UI tweaks and animations (or genuine interest in growing into that).

Bonus: prior consumer health, wellness, fitness, or nutrition product experience; design system ownership; founding / first designer at a startup.

Must be authorized to work in the U.S. as an independent contractor. No visa sponsorship for this role.

Details: https://www.doubling.io/careers/design-engineer Apply: careers@doubling.io

Revieve | Product Engineer | Remote (Helsinki HQ) | Full-time | Contractor/Vendor

Revieve builds AI-powered personalization for 120+ beauty brands across 40+ countries — think skin analysis, AR try-on, and recommendation engines used by some of the world's largest retailers. We're profitable, ~30 people, a dozen engineers, millions of end users.

We've reorganized around the idea that one builder with the right tools can do what teams used to. This role exists because we believe that's true.

What a week looks like: Mon — a real customer problem lands in front of you, full context, you decide what to build Tue — prototype in Claude Code, something running by EOD Wed — staging up, Loom to founders, iterate on notes Thu — in production, watching real data come in Fri — ship the next iteration or find the next problem

~1–2 hours of meetings per week. No standups. No sprints. No PM in the loop.

We're looking for: → Public proof of building — repos, side projects, real users. We click around it. → AI in production — not demos. Opinions on agents, evals, latency, what fails. → Agentic coding fluency — Claude Code, Codex, MCP, custom harnesses → TypeScript / React generalist — comfortable at any layer → Design taste — you know what's wrong with a screen without a designer telling you → Clear written thinking — READMEs, PRs, post-mortems

IMPORTANT: include a link to something you've built in your application.

Process: recruiter call → paid build session (real problem, you set the pace) → short presentation → done.

Perks: 5 weeks vacation from day one, remote-friendly, options plan, equipment budget, parental leave, competitive salary.

Stack: TypeScript, NestJS + Fastify, React, Valkey, PostgreSQL, Docker, Kubernetes, Terraform, AWS.

We ship OSS self-hosted and have a live cloud SaaS: https://betterdb.com/login In the last two months we've averaged more than one release per week across multiple products and channels.

Sweet! How strict are you about YoE? I have 3 YoE and previously a Founding Engineer at a startup.

Asking because on the careers page, I only see Staff/Principal/Tech Lead roles.

I am very product obsessed. I care a lot about building the right thing and building it the right way, not just writing cool code. I have a pretty strong sense for balancing speed vs code quality. I know when to just ship and when something needs to be done properly.

Right now we're focused on finding more experienced hires so this one won't be quite right by the sounds of your experience.

Fortech Engineering | Full Stack Software Engineer | Primarily remote (Waterloo region, Canada) | $140-170K CAD + performance pay + earned equity

Electrical and mechanical engineering consulting firm in Waterloo, serving the Canadian building construction industry — a market that's still mostly designed the old way. I designed the original platform schema and UX vision; my early code attempts got abandoned when running and growing the firm took priority. The years since have been spent figuring out how to scale this properly and fill those gaps. We're now at the depth and size to support a real build — with no committee in the way, and with my time properly committed to it this time. I'm hiring an exceptional software engineer to take it to the production platform it was always meant to be.

Real users, direct collaboration with the founder, and 20 years of MEP practice plus the platform vision. Few founders building automation in this space bring both.

Profitable, bootstrapped, 18 years old. Equity is earned, not granted — a real cut of a real business, not options in something that may or may not happen.

Stack: TypeScript, React, Tailwind, shadcn/ui, AG Grid, TanStack Query, Drizzle, PostgreSQL, Python (FastAPI), Node.js, Docker.

Looking for: full-stack, agentic-first as a daily working mode, shipper not writer.

Chestnut | Senior Product Engineer | SF or Seattle (Hybrid) | https://jobs.ashbyhq.com/Chestnut

I'm Nick, CTO & co-founder. We're Rippling, but for insurance carriers paying their sales force. Every policy sold triggers a chain of payouts across brokers, agents, and sub-agents. Today that runs on spreadsheets and legacy vendor systems and tomorrow they'll run on Chestnut. Nationwide and other major carriers have already made the switch.

Revenue is up 8x in the last year. We're backed by a16z. Founding team came out of leadership at Ethos (insuretech that recently IPO'd in January).

The work is state-heavy and correctness-critical: payouts that must reconcile with finance to the cent, dynamic agent hierarchies, retries, chargebacks, partial failures. These systems move real money and cannot drift.

You'll design schemas, build backend logic, ship UI, deploy, and own the sharp edges that show up with real enterprise customers.

Stack: Go, TypeScript/React, Postgres, Temporal, Kubernetes, AWS. We use AI aggressively and expect you to as well.

We're looking for 3–6 years on real product systems. You're thoughtful about invariants and failure modes.

Hey HN! Air Space Intelligence (https://www.airspace-intelligence.com) is hiring. We are a frontier AI and product company for the critical industries and defense, backed by a16z.

We’re rebuilding America’s air traffic control system from scratch. What we do in the next two years will define how this country moves through the sky for the next fifty.

At the core is one of the largest real-time optimization problems in the world: how do you safely sequence ~40,000 flights/day while routing around weather, military airspace, equipment outages, and constant real-world churn? The system has to be right every time, and reliable at scale.

We’re hiring across Backend, Infrastructure, and Frontend (ICs and Tech Leads).

One of our roles (with a small puzzle at the bottom that routes to my email): https://www.airspace-intelligence.com/careers/role?=1336c828... - include “HackerNews” in the subject so I can prioritize.

If you want a problem that is genuinely hard, consequential, and urgent - this is the moment to reach out.

There’s a note that there are “mandated certifications” with the federal government required for hire - is that a security clearance, or something simpler?

Given the last couple of years accidents, I hope you can improve safety here!

Applied. Looks neat

Pango | Senior Software Engineer - Full Stack, Technical Lead / Software Engineer | On-site (hybrid) in Stockholm, Sweden (Visa Sponsorship possible) | Full time

Pango is building the world's first Agentic Operating System for e-commerce logistics. Our vision is to create the AI e-commerce employee of the future. We are forming our core team in Stockholm and are looking for exceptional engineers.

You are a good fit if:

* You are comfortable maintaining, expanding and operating a substantial chunk of a B2B SaaS platform with a high sense of ownership.

* You are happy to take on work that in a large company is divided into multiple roles, and execute it all at an excellent level.

* You are unafraid of any technology. If we need a desktop app and you haven't done one before, you will study the documentation of Electron.js and build one. If a model for predicting delivery times is needed, you will do a literature review to find the right architecture and train one.

* You have strong proficiency in any backend language or platform, with a strong willingness to dive deep into PHP/Laravel OR strong proficiency in JS/React.

* E-commerce (Shopify, Magento, other platforms, shipping carrier integrations) experience is a plus.

* Extra points if you write the initial email - however short - using your own words.

You will take a key role in shaping the product and company, with ability to make an impact and advance career limited only by your aptitude and interest.

Reach out to lukasz@pango.ai if you are interested or have any questions. We review applications immediately and move quickly.

Hey Lukas, would you be open for the remote position? I follow the Sweden time so i guess so that won't be any issue. Let's have chat and connect to discsuss it further.

Because I'm curious, how come you picked php for the backend?

It started with a founder's preference and also some desire to make a point (the point being that PHP makes an extremely solid foundation for web application development) and continued with it revealing itself as a useful attitude, skill and maturity filter when hiring.

Not hiring, but actively helping healthcare AI startups navigate compliance challenges.

If anyone here is working on health AI and running into HIPAA compliance walls (PHI handling, audit requirements, BAAs with vendors), happy to share what I've learned from consulting with 12+ startups in this space.

The compliance tax on healthcare AI is brutal, but there are patterns and tools that make it manageable.

Feel free to reach out if you're in this domain - always interesting to compare notes on real-world compliance implementations.

Fastly | Software Engineers (Senior, Staff, Principal) | REMOTE (US, UK, EU) or ONSITE | Full-time

We're a globally edge cloud platform for performance and security, emphasizing open standards, sustainable engineering, and resilience-by-design. We're hiring across compute, security, platform engineering, network and edge protocols, release engineering, network architecture, client services engineering, and more.

* Apply: https://www.fastly.com/about/careers

QUIC, but TCP experience and not UDP? Sorry, being a little pedantic but it's a real question.

You can't rely on UDP experience.

We didn't want to get too wordy with a post like this. But to be honest, if you are knowledgeable enough to spot that kind of gap, you might be a perfect fit for what we are working on ;)

HelpMyCash is a Barcelona-based financial comparison platform. We're looking for a senior freelance DevOps/SRE to act as the operational safety net for a mature AWS production platform.

This is explicitly an insurance role: keep the platform reliable, no major evolution or greenfield work. The platform has run reliably for years (no critical outages unrelated to deploys/changes in 5+ years) — we want someone to keep it that way.

Engagement: ~4h/week retainer paid on-call for critical incidents planned/larger tasks quoted separately fully remote, EU/CET, reachable during Spanish business hours

Compensation: retainer + hourly rate + on-call premium for out-of-hours response. Exact structure and rates open to discussion based on your model.

We're hiring a Principal Platform Engineer to own our cloud infrastructure and developer platform: AWS, containers, Terraform, CI/CD, observability, and the self-service tooling that lets our application teams ship quickly inside a regulated SDLC.

We are looking for: 7+ years in DevOps/SRE/platform roles, deep AWS, strong IaC, comfort with containers (ECS/Fargate, Kubernetes), and one language you reach for when building tooling (Python, Go, Rust, Ruby, C++). Healthcare or regulated-industry experience is a plus, but not a requirement.

Hi HN! We’re an energy + AI startup that applies modern deep learning and optimization to improve the use of renewables and grid-scale batteries to deliver cheap, clean energy to commercial/industrial customers. We also do energy trading and battery optimization.

Roles:

- Data engineer: we're hiring our first data eng! Looking for a startup-minded SWE to work on both ingest and transformation of datasets that power our best-in-class ML models for energy forecasting.

- Product engineer: our energy sales have been growing rapidly and we want to 10x it from here, which involves building a lot of tooling to make sales more automated. This tends to be backend/data heavy, but will also have some frontend (NextJS/React/Typescript).

If you're interested in making a real-world impact on climate/energy, or if you know someone that might, please email me and include a one sentence description of the most impressive thing you've built: kevin@gridmatic.com

Stream | Amsterdam (NL), Skopje (North Macedonia)| Remote possible | Full Time | Visa Sponsorship

We power real-time Chat, Video, Activity Feeds, and AI Moderation for apps like Strava, Bumble, eBay, and Patreon - billions of API requests per month, millions of concurrent users.

We're looking for a hands-on Lead Engineer (Staff / Principal level) to own Platform & Infrastructure.

Reports directly to the CTO.

Small, senior team - you'll write code most of the time, not run a process org. First 6 months focus on three things with measurable outcomes:

* Cloud cost optimization (AWS/GCP) — tooling and guardrails, not reports

* Platform reliability and scalability — SLOs, observability, hardening

* Architecture decisions on Kubernetes, databases, and cloud provider strategy

Stack: Go, Python, AWS, GCP, Kubernetes, PostgreSQL, CockroachDB, Redis, Terraform.

Looking for: software engineering background (Go or Python, not scripting-only), production cloud cost optimization experience, real distributed systems depth, and active AI tooling use in your engineering workflow.

Not a fit if: you're security/compliance-heavy, scripting-only, or dependent on large-org support structures.

Full JD + apply here: https://jobs.ashbyhq.com/stream/cbabbb5d-0e34-486b-acf7-ce40...

*Labor Solutions (YC-style) | Senior Software Engineer | Remote (India) | Full-time*

We run a worker wellbeing and compliance platform used by global buyers and their supply chain sites across Asia. We're in the middle of a meaningful migration and platform buildout — you'd be joining at a point where architectural decisions matter and your fingerprints will be on the system for years.

*The work:* Our stack is Django + Python on the backend, dbt for data transformation, React/Next.js on web, and Expo/React Native for mobile. We run on AWS and Azure. Right now we're migrating legacy services while simultaneously shipping new features — so you'll need to be comfortable holding both in your head.

*What we're looking for:*

- Strong Python/Django chops — you've built and maintained production APIs, not just tutorials - Comfortable with React/Next.js; bonus if you've touched Expo or React Native - You understand what a data pipeline actually does (dbt experience a plus, but SQL fluency matters more) - Cloud experience on AWS or Azure — not ops, but enough to not be blocked - You care about code quality without being precious about it

*What this isn't:* This isn't a greenfield startup with infinite runway. It's a real product with real users, real technical debt, and a migration in progress. If that sounds like a problem, this role isn't for you. If that sounds like the most interesting kind of work, let's talk.

*Details:* - Fully remote, India-based - Senior Software Engineer title

Recover Systems | Founding Engineer | Onsite in Portland, Maine | 130-160k + meaningful equity from first option pool

Recover is building the infrastructure for all restoration work, streamlining how remediation contractors run jobs while we handle the red tape and headaches. Recover is a platform born from insurance requirements, financial ledgers, spatial intelligence; built to collapse hundreds of messy painpoints into a single flow.

We've just closed our seed round, live desktop and IOS app and are ramping up to convert demo offices to live deployments and rolling out to 50+ waitlisted offices. We're sprinting fast to cover the last features in V1 roadmap including subcontractor portal and insurance disputes workflows and one-click materials marketplace.

We're hiring for a specific type of engineer:

PM-minded engineer for messy domains. The rare hybrid who can sit across from an insurance adjuster, a franchisee, and a senior estimator in the same day, walk away with the actual workflow in their head, and collapse a scattered process into a single screen the technician actually wants to open. Owns the full loop: stakeholder interview → spec doc → spreadsheet model → prototype → production. Equal parts taste, insight, and stamina. Ships features that flow smoothly and improve how work gets done.

Y Combinator | Product Engineers on YC's own team | San Francisco | Full Time | $185K-$485K

I'm Ryan, an EM and engineer here at YC. We have a small, 18-person software team with no PMs -- engineers own everything end-to-end.

We build the software behind YC's $6B in investments: tools that help partners evaluate thousands of startups per batch, AI-powered apps that founders use every day, and platforms like Work at a Startup that connect candidates with YC companies. Engineers get unlimited AI tokens -- both for development and to build AI-powered products. What wouldn't you build to help founders + YC with that much firepower?

What makes this different from other roles:

* You'd learn more about startups here than you could possibly imagine. Every batch brings hundreds of founders building things across every industry, and you're right in the middle of it.

* We attend Demo Day, founder dinners, and work directly with partners and many of the companies. (They make great products!)

* We pay well, offer carry in the fund (like equity), and provide generous relocation support if you're not in SF yet.

Two roles open:

* Product Engineer -- full-stack, own the product lifecycle. Rails/React stack. Build tools that power how YC invests in and supports startups. It's a wide range, and sometimes it feels like labs-like work, other times it feels like a supersuit to power founders and our Partners like Garry and Jared.

* Community Builder and Software Engineer -- hybrid role. Run YC's talent-facing programs (meetups, tech talks, career expos) AND build the software that makes them scale. You need to be a great engineer and LOVE to build and support communities.

Checkout more about the roles, and email me directly if you're excited to learn more about startups than you will anywhere else - ryan@ycombinator.com

Level 12 | Full Stack Web Developer - Python, JavaScript, SQL | Mid-Level & Senior | REMOTE | SALARY:$95K-145K+ | https://www.level12.io/careers/

Level 12 is a software consulting and custom development agency. We have mid and senior level positions. Our job descriptions are written by developers for developers. No HR fluff here, we want you to know what you are really getting into:

https://www.level12.io/careers/

- We have a commitment to transparency and offer a "no surprises experience" throughout the interview and hiring process. We value candor...as evidenced by the length of our job description. :)

- Our CEO prefers the title CED, Chief Executive Developer. Engineering and operational concerns don't take a back seat when potential sales come to the front door.

- You will be working remote with a team that is all working remote and has been for years. Let's make the best use of our time by not commuting.

- We practice and preach sound development practices. You are likely to learn and grow as a developer while working here.

- You are committed to automated testing of all the software you write (our apps typically have 92%+ test coverage).

- We have a no-drama office policy. We value and cultivate enjoyable working relationships among team members. No jerks allowed!

- We emphasize work/life balance and adopt policies that make sure our people don't get burnt out. For instance, our PTO/Vacation policies are designed so that you actually use them.

- If you apply, we guarantee that we will give you a response, whether "yay" or "nay". No black holes here!

- Hiring status & updates: https://github.com/level12/careers

I am a qualified candidate and would like to apply for this position, however, before doing so, I have an inquiry. My country's laws allow me to work for a US based company on contract basis, the major qualification drawback I have based on the position description is the timezone. I am on a different time zone specifically EAT (UTC+3). Is location within the same time zone as the US a mandatory requirement or can I fix my work schedule to conform with the US timezone?

I'm a senior level dev looking at the senior role, but it says 2-3 years of python experience at minimum. I don't have that, so I thought I'd look at the mid-level role which says "3-6 years developing database-driven web applications with (preferably) Python" but then "candidates without Python experience may still be considered if they have experience with similar tech."

How True is this? Have you hired anyone before with experience but that didn't have a lot of python experience? I've mostly worked in node, but I've done a little with python and could start some django courses this weekend if you're actually giving people shots here.

It's a good question and I should update those sections to make Python a harder requirement.

We've tried to be flexible historically but found that we really need folks who are fluent in Python because our skills tests all use Python and we need devs to hit the ground running on day 1 and all our projects are in Python.

I did recently hire a dev whose Python is a bit rusty but who made it through the skills tests. But, for the most part, devs without solid and recent Python experience aren't getting through our skills tests.

By turning legal code into AI code, Norm enables enterprises to move faster and more comprehensively in their legal and compliance processes with reliability and trust. Norm Ai, the leading Legal & Compliance AI company, has a client base with a combined $30 trillion in assets under management. Norm’s platform combines frontier AI, proprietary legal reasoning systems, and embedded legal and regulatory expertise.

We have recently raised more than $140 million, backed by Blackstone, Bain Capital, Vanguard, Citi, New York Life, TIAA, Coatue, Craft Ventures, Henry R. Kravis (KKR co-founder), and Marc Benioff (Salesforce CEO).

Norm Ai pioneered Legal Engineering, the process that empowers lawyers to build and supervise domain-specific AI agents with Norm’s proprietary suite of no-code software tools. We hired dozens of lawyers from premier U.S. law firms and trained them as Legal Engineers, who specialize in Large Language Model powered legal workflows.

Norm Ai technology is deployed inside many of the largest and most consequential institutions in the world. The company is growing quickly and hiring in NYC across all teams, including:

- Full Stack Engineer, Senior + Staff ($190k-280k)

Kanmon | Senior FullStack Engineer | Hybrid (San Mateo) |

If remote, please be prepared for an in person technical interview.

For remote talent, must be US based.

Kanmon is built around B2B finance and it's one of the largest and most broken markets in the world. SMBs are 44% of US GDP and extend over $5 trillion in trade credit to each other every year yet modern financial infrastructure intermediates less than 10% of it. The rest still runs on PDFs, paper invoices, and underwriting cycles measured in months.

Kanmon is rebuilding that stack from scratch. We're the finance infrastructure that lets software platforms embed payments and working capital directly into the software their SMB customers already run their businesses on.

Kanmon has raised new capital to go a layer deeper and are building an AI cashflow and business credit copilot that helps businesses make smarter financial decisions in real time. It's a genuinely new category of product, and we're architecting it from zero.

We're hiring a senior full-stack engineer to own it. End-to-end ownership, direct line to founders, no PM handoffs.

Full stack TypeScript: React, Next.js, NestJS, PostgreSQL, GCP. Competitive comp | mags@kanmonhq.com

Acrylic Robotics | ML Lead | Montreal, QC | Onsite/Hybrid | Full-time

Acrylic Robotics is a creative tech company focused on changing how people design and create art. We build software that learns a person's taste in art, ML design tools that turn it into a concept, and robots that create the concept with paint on canvas, so original artwork can be commissioned at a price most people can actually afford.

We're hiring an ML lead to own the model side. The system has to take a user's intent and references, turn them into concepts the user can refine through feedback, and produce the brushwork-level instructions our robots paint. This would be the first dedicated ML hire on the team; they'll help set the technical direction, ship the first real end-to-end version, and build out the team behind them.

We're based in Montreal, QC, but open to a hybrid position for the right person. Please email me at walker@acrylicrobotics.ca or look at https://acrylicrobotics.ca for more info.

Thanks! - Walker, Head of Engineering
