Software Engineer, Infrastructure

Exa is an applied AI lab building a search engine. We build massive-scale infra to crawl the entire web, train state-of-the-art embedding models, and design super high performant vector databases. Our Infrastructure Team builds the underlying tooling and infrastructure that powers all Exa's systems.
