This is a building role: you'll design and develop high-performance systems, mostly in Rust, that collect billions of data points from the web. The work sits where backend engineering meets how the web works: HTTP stacks, proxies and browser tooling. When a data source blocks an approach, you'll dig into what's happening on the wire and find another way forward. You'll also help make our infrastructure "agent-friendly", so other teams can safely build on it with AI.</span></p> <h2><span style="font-family: helvetica, arial, sans-serif; font-size: 12pt;">Where you will have impact</span></h2> <ul> <li style="font-size: 12pt; font-family: helvetica, arial, sans-serif;"><span style="font-size: 12pt; font-family: helvetica, arial, sans-serif;">Design, build and improve backend systems for data acquisition that handle close to 200 million requests a day.</span></li> <li style="font-size: 12pt; font-family: helvetica, arial, sans-serif;"><span style="font-size: 12pt; font-family: helvetica, arial, sans-serif;">Work on our in-house proxy layer and browser tooling: request routing, connection handling and protocol-level behaviour.</span></li> <li style="font-size: 12pt; font-family: helvetica, arial, sans-serif;"><span style="font-size: 12pt; font-family: helvetica, arial, sans-serif;">Investigate hard crawler problems, test alternative approaches when one gets blocked, and turn what works into robust, reusable systems.</span></li> <li style="font-size: 12pt; font-family: helvetica, arial, sans-serif;"><span style="font-size: 12pt; font-family: helvetica, arial, sans-serif;">Build clear interfaces and guardrails so other teams and AI agents can use what you build reliably.</span></li> <li style="font-size: 12pt; font-family: helvetica, arial, sans-serif;"><span style="font-size: 12pt; font-family: helvetica, arial, sans-serif;">Own the quality of your code, including code written with AI assistance: tests, observability and maintainability.</span></li> <li style="font-size: 12pt; font-family: helvetica, arial, sans-serif;"><span style="font-size: 12pt; font-family: helvetica, arial, sans-serif;">Work closely with crawler engineers, DevOps and Security to ship solutions that are secure and scalable.</span></li> </ul> <h2><span style="font-family: helvetica, arial, sans-serif; font-size: 12pt;">About our team</span></h2> <div class="sc-eWidsO cXpNwe"> <div class="sc-fueQRQ jYYoIc"> <div><span style="font-family: helvetica, arial, sans-serif; font-size: 12pt;">The Crawler engineering team makes sure Lighthouse customers get fresh, high-quality rates, ranking and supply data.
