Software Engineer; Backend

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 that regularly lights up tens of thousands of machines.

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.

• You have experience writing and maintaining high throughput, low latency systems
• You can build data processing pipelines that deal with millions of documents per day
• 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
• Plus:
  Experience in some high performance language (C++, Rust, etc.)

• 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 San Francisco. We're happy to sponsor international candidates (e.g., STEM OPT, OPT, H1B, O1, E3).
