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: $235,000–$260,000 USD/year (SF) / $217,000–$233,000 CAD/year (Toronto) Equity Range: Competitive equity. Details shared during the process. Location: San Francisco, CA (SF HQ) or Toronto, ON (Toronto Hub). Hybrid, onsite 3+ days a week. Job Type: Full-Time Experience: 3+ years in backend, networking, or infrastructure engineering Work Authorization: Open to candidates already authorized to work in the US or Canada. In the US, we also support H-1B transfers, F-1 OPT and STEM OPT, TN (Canada and Mexico), and E-3 (Australia). We’re not able to sponsor new H-1B visas for candidates outside the US. For Canada, we’ll consider work permit sponsorship case by case through our Toronto Hub. ### 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. It's the boring-hard problem everyone building with LLMs eventually hits, solved. In September 2026, we raised a $75M Series B led by Smash Capital, and we're spending it building the largest repository of knowledge in the world. We hit 8 figures in ARR in year one and more than doubled it in year two. We have 187k+ GitHub stars, putting us in the top 40 repositories of all time, 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. That library is called Alexandria, and it starts now. ### Our Values Bias to action: We move fast, ship hard, and don’t wait to be told. Realistic about AI: We’re clear-eyed about what AI can and can’t do, and we keep pushing to use it where it actually works. All in: The next few years matter a lot, and we’re all in for them. Human connection: As intelligence gets cheaper, relationships with customers, partners, and each other matter more. ### 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. ### Benefits & Perks ### Available to all employees --- Data: alder (https://alderhq.app).
