About this role

This position is based at the San Francisco HQ or Toronto Hub on a hybrid schedule, requiring employees to be onsite 3 or more days a week. It suits an engineer who enjoys reverse engineering obfuscated code, analyzing web detection systems, and shipping production fixes rapidly.

Role Overview

Firecrawl is seeking a Web Automation Engineer to keep its platform connected to the open web by building resilient scraping infrastructure. The role focuses on researching automated traffic detection systems, understanding how they operate, and turning those insights into fast and reliable web automation tools.

Key Responsibilities

Research how modern websites detect and challenge automated traffic, and examine underlying mechanisms and challenge flows.
Identify browser, device, network, and behavioral signals that separate automated access from human traffic.
Replicate signals synthetically in authorized test environments to validate and harden scraping approaches.
Build automation, diagnostic, and monitoring tools to maintain high scrape reliability as the web changes.
Own scrape success rates, explain regressions, and ship necessary fixes.
Collaborate with platform engineers to roll out improvements across the crawling fleet at scale.

Requirements

Strong proficiency in JavaScript, TypeScript, and/or Python, with the ability to adapt to language demands.
Real understanding of browser rendering, JavaScript engines, headless automation, and differences between automated and real browsers.
Solid grasp of HTTP/TLS, proxies, and browser and device fingerprinting.
Reverse-engineering instincts to read minified and obfuscated code and determine its checks.
Ability to research deeply and land fixes directly into production.
3+ years of experience building browser automation, web infrastructure, or systems-level software.

Nice to Have

Experience deobfuscating JavaScript and VM-based obfuscation.
Familiarity with network-level fingerprinting, including TLS and HTTP2 signatures along with JA3 or JA4.
Background running large browser or proxy fleets in production.
Prior work experience at a scraping, web data, security research, or automation company.
