Software Engineer, Backend

Exa
Singapore · Full-time · Entry

Exa is building a search engine from scratch to serve every AI application. We build massive-scale infrastructure to crawl the web, train state-of-the-art embedding models to index it, and develop super high performant vector databases in Rust to search over it. We also own a $5m H200 GPU cluster and routinely run batchjobs with tens of thousands of machines. This isn't your average startup :)

As a backend engineer, you'd play a critical role in our backend system. We're pretty flexible on what projects people work on based on their skills and interests.

Desired Experience

  • You have experience with some high performance language (C++, Rust, etc.)
  • You’re comfortable optimizing a system to an exceptional degree
  • You care about the problem of finding high quality information and recognize how important this is for the world

Example Projects

  • Recreate Google-level keyword search over 10 billion pages in 1 month
  • Build a state-of-the-art crawling system that works optimally for any website
  • Build a custom vector database that runs over a billion vectors in under 100ms

This is an in-person opportunity in Singapore.

Compensation Range: $150K - $300K
