Backend Engineer
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 and routinely run batchjobs with 10s of thousands of machines. This isn't your average startup :)
As a backend engineer, you'd play a critical role in lots of our backend systems. We're pretty flexible on what projects people work on based on their skills and interests.
Desired Experience
You have experience with some high performance language (C++, rust, etc.)
You’re comfortable optimizing the crap out of a system
You care about the problem of finding high quality information and recognize how important this is for the world
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).
Average salary estimate
If an employer mentions a salary or salary range on their job, we display it as an "Employer Estimate". If a job has no salary data, Rise displays an estimate if available.
