Software Engineer, Web Crawling

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 Web Crawler engineer, you'd be responsible for crawling the entire web. Basically build Google-scale crawling! DESIRED EXPERIENCE - You have extensive experience building and scaling web crawlers, or would be excited to ramp up very quickly - You have experience with some high performance language (C++, Rust, etc.) - You are familiar with TypeScript, Playwright, modern web design, CDP (Chrome DevTools Protocol) - You’re comfortable optimizing a system to an exceptional degree - You care about the problem of finding high quality knowledge and recognize how important this is for the world EXAMPLE PROJECTS - Build a distributed crawler that can handle 100M+ pages per day - Optimize crawl politeness and rate limiting across thousands of domains - Design systems to detect and handle dynamic content, JavaScript rendering, and anti-bot measures - Create intelligent crawl scheduling and prioritization algorithms for maximum coverage efficiency 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.
