The Role
As a Backend Engineer, you will work on high-performance systems for search, optimizing production services, and handling vast amounts of textual data. You'll tackle projects like recreating large-scale search functionalities and enhancing document parsing capabilities.
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.
