Software Engineer, Web Crawling

Exa is an applied AI lab building a search engine unlike the world has ever seen. We build massive-scale infra to crawl the entire web, train state-of-the-art embedding models to process it, and design super high performant vector databases to retrieve over it. We now power search for Cursor, Cognition, HubSpot, and over 400,000 developers and have raised $350m from Lightspeed, Benchmark, and a16z.  Our ultimate goal is to build perfect search over all the world's information, far beyond Google. If you want to build massive-scale ML systems that will define the way the new AI world consumes information, this is the place for you.  As a Web Crawler engineer, you'd be responsible for crawling the entire web. Basically build Google-scale crawling! Who You AreYou 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 DoBuild 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 sch
