Research Engineer
You'll build the evaluation systems that tell us whether Firecrawl actually works. That sounds simple. It isn't. Our core promise, convert any URL into clean, structured, LLM-ready data reliably, is hard to measure rigorously across millions of different websites, formats, and edge cases. As the systems we're measuring get more complex, the question "did that work?" gets harder, not easier.
This isn't an eval role where you inherit a framework and run benchmarks. You'll design the metrics, build the pipelines, generate the datasets, and own the feedback loop from output quality back to model and product decisions. If you care about what "good" actually means and have the engineering depth to measure it, this is the role.
Salary Range: $210,000–$275,000/year (Range shown is for U.S.-based employees in San Francisco, CA. Compensation outside the U.S. is adjusted fairly based on your country's cost of living.)
Equity Range: Up to 0.05%
Location: San Francisco, CA or Remote (Americas, UTC-3 to UTC-10)
Job Type: Full-Time
Experience: 4+ years in ML, research engineering, or data-heavy backend, with real evaluation work
Visa: Must already be authorized to work in the US or our eligible remote-hire regions. 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 147k+ 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
Design the metrics that define what "good output" actually means across millions of sites, formats, and edge cases
Build the pipelines and harnesses that measure quality rigorously and at scale
Generate and curate the datasets that make evaluation trustworthy
Own the feedback loop from output quality back to model and product decisions
Turn "did that work?" into an answer the whole team can act on
What We're Looking For
You have the engineering depth to build real evaluation systems, not just run existing ones
You care deeply about what "good" means and how to measure it rigorously
You're comfortable owning ambiguous problems where the metric itself has to be invented
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 only wants to run benchmarks someone else designed
A pure researcher who won't build the systems, or a pure engineer who won't think about methodology
Someone who needs a fully-specced ticket to start
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 — eval systems, metrics you designed, datasets you created, quality problems you measured. 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 — how you'd measure whether messy web output is actually "good," and build the system to prove 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 evaluation problem — 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 you care about what "good" actually means and have the engineering depth to measure it, you should join us.
