About the Role

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. You'll own real infrastructure from day one, not tickets in a backlog.

Responsibilities

  • 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

Requirements

  • 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
  • Must already be authorized to work in the US or our eligible remote-hire regions.

Location

  • San Francisco, CA
  • Remote (Americas, UTC-3 to UTC-10)

Work Type

  • Full-Time
  • Remote

Experience Level

  • 3+ years in backend, networking, or infrastructure engineering

Salary/Compensations

  • $200,000–$250,000/year

Benefits

  • Up to 0.05% equity
  • 15 days mandatory PTO, anything after 24 days, just ask (holidays excluded)
  • 12 weeks fully paid parental leave
  • $100/month wellness stipend
  • Up to $1,000/year for learning and development
  • Team offsites
  • 3 paid months off after 4 years sabbatical
  • Medical, dental, and vision (100% for employees, 50% for spouse/kids) (US-based)
  • Employer-paid short-term disability, long-term disability, and life insurance (US-based)
  • Optional accident, critical illness, hospital indemnity, and voluntary life insurance (US-based)
  • Doctegrity telehealth (US-based)
  • 401(k) plan (US-based)
  • FSAs and commuter benefits (US-based)
  • Pet insurance (US-based)
  • Snacks, drinks, team lunches, intense ping pong, and peak startup energy (SF-based)
  • A loaner electric bike (SF-based)

About the Company

  • 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.
  • 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.
