Responsibilities
- Research and implement anti-bot evasion techniques.
- Reverse engineer bot detection systems. Understand how they work, then bypass them.
- Work with browser fingerprinting: canvas, WebGL, audio, fonts, navigator properties, and more.
- Debug TLS fingerprinting (JA3, JA4, HTTP/2 fingerprints).
- Optimize Playwright/Puppeteer configurations for stealth.
- Analyze network traffic to understand detection mechanisms.
- Build internal tools for testing and validating evasion techniques.
- Stay ahead of the latest developments in bot detection.
- Document findings and share knowledge with the team.
Requirements
- Deep experience with Playwright, Puppeteer, or Selenium internals.
- Understanding of browser fingerprinting techniques and how to spoof them.
- Experience bypassing at least one major anti-bot system (Cloudflare, Akamai, DataDome, PerimeterX, etc.).
- Network traffic analysis (Wireshark, Burp Suite, mitmproxy, or similar).
- BSc or higher in CS or equivalent technical field.
Nice to Have
- TLS fingerprinting experience (JA3, JA4, HTTP/2).
- WebRTC fingerprinting and evasion.
- Chromium or Firefox source code familiarity.
- Experience at scale handling millions of requests.
- Contributions to open-source evasion tools.
Benefits
- Fully Remote. Work from anywhere.
- Equity share. Own a piece of what you're building.
- Profit sharing. When we win, you win.
- Learn fast. Work on some of the hardest problems in web scraping.
- Annual team retreats (last one in Spain).
