  • 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.)
More about this role

Exa is an applied AI lab building a search engine unlike the world has ever seen. We build massive-scale infra to crawl the entire web, train state-of-the-art embedding models to process it, and design super high performant vector databases to retrieve over it. We now power search for Cursor, Cognition, HubSpot, and over 400,000 developers and have raised $350m from Lightspeed, Benchmark, and a16z.
