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 an engineering intern, you'd play a critical role in lots of our projects. We're pretty flexible on what projects people work on based on their skills and interests.Desired ExperienceCurrently pursuing a degree in Computer Science, Engineering, Physics, or a related technical field AND are willing to take off a semester to work full time in SF. Remote and part-time interns are not accepted.You have experience with some high performance language (C++, Rust, etc.)You often code technically difficult or interesting projects for funYou care about the problem of finding high quality information and recognize how important this is for the worldExample ProjectsRecreate Google-level keyword search over 10 billion pages in 1 monthBuild a state-of-the-art crawling system that works optimally for any websiteBuild a custom vector database that runs over a billion vectors in under 100msThis is an in-person opportunity in San Francisco. We're happy to sponsor international candidates (e.g., STEM OPT, OPT, H1B, O1, E3).
