Research Engineer, Generalist

We raised a $250M Series C to build the search engine for AIs. Led by a16z, with existing investors Benchmark, Lightspeed, and YC doubling down, the round brings Exa's valuation to $2.2 billion. Read more

Exa is building a search engine from scratch to serve every AI agent. We build massive-scale infrastructure to crawl the web, train state-of-the-art embedding models to process it, and design super high performant vector databases in rust to search over it. If you like compute, we also own a $5M H200 GPU cluster (and soon 5x'ing that) and regularly spin up batchjobs with tens of thousands of machines.

We are rapidly building the most intelligent search engine in history. We’re high agency, low-ego, and united by the feeling that this is one of the last problems worth getting right.

Generalist Research Engineers work across our search and retrieval stack: crawling, parsing, ML performance, retrieval algorithms. The team is centered around improving end quality of search endpoints for customers.

Who You Are

• High attention to detail; simultaneously understand customer needs and implementation details of the system

• Great intellectual horsepower - generalists who are eager to go deep

• You're excited to work across our search and retrieval stack: crawling, parsing, ML performance, retrieval algorithms and more

• Comfortable working across different systems, and shipping fast

• You care about the problem of finding high quality information and recognize how important this is for the world

What You Could Do

• Design and ship a new parser that dramatically improves retrieval performance

• Improve throughput and latency of ML models

• Make our web crawler 3x faster

This is an in-person opportunity in San Francisco. We're happy to sponsor international candidates (e.g., STEM OPT, OPT, H1B, O1, E3). In addition to premium healthcare benefits (medical, dental, vision), we also offer fertility benefits and a monthly wellness stipend to all of our employees.
