I don't see any jobs in Prague in the list, am I looking wrong?

Also, I have background in (research) AI, reasoning, semantic web, and experience (software engineering) around hadoop and search/information retrieval, (education): machine learning, medical informatics, biology of the cell. I see many possible matches in the US-based jobs. Is there an option for a broader application where you would suggest a good match?

Would it be possible to perform some of the roles offered for US in continental Europe or truly remotely?
