Backend Infrastructure Engineer

Youll work on the infrastructure that makes Firecrawl fast and reliable against a web that constantly changes and fights back. This is deep systems work: keeping success rates high against sites with aggressive defenses managing the proxy layer that powers reliable data collection at scale and pushing throughput and reliability under heavy spiky load. When Firecrawl just works on a site that tries hard to stop it thats this team. Youll own real infrastructure from day one not tickets in a backlog.

About Firecrawl

Firecrawl is the easiest way to turn the web into data AI agents can use. One API call converts any URL into clean LLM-ready markdown or structured data - the boring-hard problem everyone building with LLMs eventually hits solved.

We hit 8 figures in ARR in year one and more than doubled it in year two. We have 147k GitHub stars and developers agents and category-defining AI companies build on us every day. Growth like this is rare and were just getting started.

Were a small team punching far above our weight. Everyone here owns a real piece of the product and company end to end and runs it themselves - no hiding behind process or headcount.

This is a place for people who want to work at the frontier: an AI company building the infrastructure other AI companies run on not one bolting AI onto an existing product. We move fast go deep and are building the tools superintelligence will rely on to gather data from the web.

What Youll Do

• Build and maintain the infrastructure that powers reliable data collection at scale

• Improve success rates against sites with aggressive defenses

• Push throughput and reliability under heavy spiky real-world load

What Were Looking For

• Youve worked on networking proxies or high-throughput backend systems

• Youre relentless about reliability and comfortable in messy adversarial problem spaces

• You can own a system end to end and keep it healthy in production

• Someone who needs the environment to be stable to do their best work
