Backend Engineer

Exa is building web-scale systems for search. We routinely run batch jobs with >1000 machines and develop production services that involve many terabytes of text. Up for the challenge?

Desired Experience

• You have extensive LLM prompt engineering experience, or would be excited to ramp up very quickly
• You have experience with some high performance language (C++, rust, etc.)
• You’re comfortable optimizing the crap out of a system
• Care about the problem of finding high quality knowledge and recognize how important this is for the world

Example Projects

• Recreate google-level search over 10 billion pages in 1 month
• Manage and optimize the prompts across any LLM calls
• Revamp our document parser to work for any website
• Make a custom vector database run over a billion vectors in under 100ms

We are open to sponsoring International candidates (e.g STEM OPT, OPT, H1B, O1, E3)

This is an in-person opportunity in San Francisco. We're big believers in in-person culture!
