Software Engineer, Backend

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 400000 developers and have raised $350m from Lightspeed Benchmark and a16z.

Our ultimate goal is to build perfect search over all the worlds information far beyond Google. If you want to build massive-scale ML systems that will define the way the new AI world consumes information this is the place for you.
