The Role
As a Backend Engineer at Exa, you will work on high-performance systems for search, optimizing LLM calls and developing solutions that handle vast amounts of data. Responsibilities include recreating advanced search systems and managing document parsing tasks effectively.
Summary Generated by Built In

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!

What We Do

Exa was built with a simple goal — to organize all knowledge. After several years of heads-down research, we developed novel representation learning techniques and crawling infrastructure so that LLMs can intelligently find relevant information.
