Software Engineer, Web Crawling

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. As a Web Crawler engineer, you'd be responsible for crawling the entire web. Basically build Google-scale crawling! Who You Are 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 What You Could Do 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.
