## About the role

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

- 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
