Web Automation Engineer
Confirmed on the employer's own hiring board on Oct 16, 2026. First seen by Alion on Sep 16, 2026. Firecrawl scores B on the Alion truth index.
Web Automation Engineer
You'll keep Firecrawl connected to the open web. Every product we ship depends on reliably accessing pages at web scale, and the modern web actively resists automation with detection systems, challenge flows, and fingerprinting that evolve weekly. This role is equal parts research and engineering: understand how those systems work at the deepest level, then turn that understanding into infrastructure that keeps our scraping fast, reliable, and resilient. If you like taking apart obfuscated JavaScript on a Tuesday and shipping the fix to production on Wednesday, this is for you.
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 building browser automation, web infrastructure, or systems-level software
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.
What You'll Do
Reverse engineer detection: Research how modern websites detect and challenge automated traffic, and take apart those mechanisms and challenge flows
Find the signals: Identify the browser, device, network, and behavioral signals that separate automated access from human traffic
Replicate and harden: Reproduce those signals synthetically in authorized test environments to validate and harden our approaches
Turn research into production: Build the automation, diagnostic, and monitoring tools that keep scrape reliability high as the web shifts
Own scrape success rate: Measure it, explain regressions, and ship the fixes
Ship fleet-wide: Work with platform engineers to roll improvements out across the crawling fleet at scale
What We're Looking For
Languages: Strong JavaScript/TypeScript and/or Python, and comfortable picking up whatever a problem demands
Browser internals: Real understanding of rendering, JS engines, headless automation (CDP, Playwright, Puppeteer), and where automated browsers differ from real ones
Network fundamentals: Solid grasp of HTTP/TLS, proxies, and browser and device fingerprinting
Reverse-engineering instincts: You can read minified, obfuscated code and figure out what it's actually checking
Research with a shipping habit: You go deep on how something works, then land the fix in production, not just a writeup
Nice to have: Deobfuscating JavaScript and VM-based obfuscation, network-level fingerprinting (TLS/HTTP2 signatures, JA3/JA4), running large browser or proxy fleets in production, or prior work at a scraping, web data, security research, or automation company
What We're NOT Looking For
Needs a spec: Someone who needs a fully specced ticket to start
Narrow lane: Someone who wants to specialize narrowly and hand off everything else
Process first: Someone who optimizes for process over shipping
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 taken apart: automation you've built, detection systems you've analyzed, gnarly debugging stories. 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. 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: why a page loads in a real browser but fails under automation, how a challenge flow decides what it's talking to, or debugging a sudden drop in scrape success. 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 (~40 Hours): Work with the team on a real, scoped piece of the product, 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 want to understand the web more deeply than the people trying to keep you out of it, you should join us.
