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
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
Location: This is an in-person opportunity in San Francisco.
Visas: We're happy to sponsor international candidates (e.g., STEM OPT, OPT, H1B, O1, E3). While we cannot guarantee your visa, we have historically been successful in sponsoring candidates from all over the world. If you receive an offer, our team will work hard to get you a visa.

- Ability to optimize systems efficiently
- Understanding of high quality knowledge discovery
What We Do
Exa was built with a simple goal — to organize all knowledge. After several years of heads-down research, we developed novel representation learning techniques and crawling infrastructure so that LLMs can intelligently find relevant information.
