Backend Infrastructure Engineer
Backend Infrastructure Engineer
You'll 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, that's this team. You'll own real infrastructure from day one, not tickets in a backlog.
Salary Range: $200,000-$250,000/year
Equity Range: Competitive equity - details shared during the process.
Location: San Francisco, CA (Hybrid, on-site required)
Job Type: Full-Time
Experience: 3+ years in backend, networking, or infrastructure engineering
Visa: Must be legally authorized to work in the United States. We're not able to sponsor visas right now, though that may change down the line.
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 150k+ GitHub stars, and developers, agents, and category-defining AI companies build on us every day. Growth like this is rare, and we're just getting started.
We're 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 You'll Do
Build and maintain the infrastructure that powers reliable data collection at scale
Improve success rates against sites with aggressive defenses
Own the health, rotation, and cost efficiency of the proxy layer
Push throughput and reliability under heavy, spiky, real-world load
Debug hard, intermittent failures across the stack and make them stay fixed
What We're Looking For
You've worked on networking, proxies, or high-throughput backend systems
You're relentless about reliability and comfortable in messy, adversarial problem spaces
You can own a system end to end and keep it healthy in production
You move fast and close the loop - you'd rather ship, measure, and iterate than perfect on paper
What We're NOT Looking For
Someone who wants clean, well-defined problems only
Someone who avoids on-call or production ownership
Someone who needs the environment to be stable to do their best work
A Note On Pace
We operate at an absurd level of urgency because the window for what we're building won't stay open forever. If that excites you, keep reading. If it doesn't, no hard feelings - but this role probably isn't for you.

Interview Process
Application Review - Send us your work and a quick note on why this excites you. Show us what you've built - proxy systems, networking infrastructure, reliability wins against hard targets. We care about what you've shipped, not where you went to school.
Intro Chat (~25 min) - A quick conversation to get to know each other before we go deep. We'll talk about what you've been working on, what drew you to Firecrawl, and what you're looking for in your next role. Time for your questions too.
Technical Chat (~45 min) - We'll dig into a real problem from our world - holding reliability under spiky load, keeping a proxy pool healthy, beating a site that fights back - and talk through how you'd approach it. Come ready to think out loud; we care how you reason, not whether you memorized the answer.
Founder Chat (~25 min) - Culture, pace, ownership, and how you like to work. Time for your questions too.
Paid Work Trial (1-2 weeks) - Work with the team on a real, scoped piece of the infrastructure - paid at a contractor rate. It's the truest signal for both sides: you see what building at Firecrawl actually feels like, and we see how you ship. Remote-friendly, and we'll flex around your current commitments.
Decision - We move fast after the trial.
If making Firecrawl "just work" on the sites that fight back the hardest sounds like your kind of problem, you should join us.
