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. Desired Experience 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.) Example Projects 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). #J-18808-Ljbffr Exa
