Search Engineer

FirecrawlToronto, ON
$235,000 - $260,000Onsite

About The Position

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. 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. We hit 8 figures in ARR in year one and more than doubled it in year two. We have 180k+ GitHub stars, putting us in the top 50 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, working out of SF HQ and our new Toronto Hub. 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.

Requirements

  • Strong JavaScript/TypeScript and/or Python, and comfortable picking up whatever a problem demands
  • Real understanding of rendering, JS engines, headless automation (CDP, Playwright, Puppeteer), and where automated browsers differ from real ones
  • Solid grasp of HTTP/TLS, proxies, and browser and device fingerprinting
  • You can read minified, obfuscated code and figure out what it's actually checking
  • You go deep on how something works, then land the fix in production, not just a writeup

Nice To Haves

  • Deobfuscating JavaScript and VM-based obfuscation
  • network-level fingerprinting (TLS/HTTP2 signatures, JA3/JA4)
  • running large browser or proxy fleets in production
  • prior work at a scraping, web data, security research, or automation company

Responsibilities

  • 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

Benefits

  • Salary that makes sense: $235,000–$260,000 USD/year (SF) / $217,000–$233,000 CAD/year (Toronto), based on impact, not tenure

  • Expense up to $1,000 USD/year toward anything that helps you grow professionally
  • Team offsites: A change of scenery, minus the trust falls
  • 3 paid months off after 4 years, do something fun and new
  • Medical, dental, and vision (100% for employees, 50% for partner and kids). No weird loopholes, just care that works
  • Employer-paid basic life and AD&D, short-term disability, and long-term disability. Coverage for life's curveballs
