Software Engineer, Web Crawling
90k – 300k/yr Singapore, SG on-site full time senior Dec 10, 2025
About this role
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 Singapore. We’re happy to sponsor international candidates.
In addition to premium healthcare benefits (medical, dental, vision), we also offer fertility benefits and a monthly wellness stipend to all of our employees.
