Job Description

About You

  • Strong C++. You’re comfortable reading and changing a large, unfamiliar codebase and its build system.
  • Hacker mindset. You enjoy reverse engineering and figuring out how systems give themselves away.
  • Browser internals. You understand fingerprinting and how to spoof it where it actually lives.
  • Persistent. You don’t give up when a single request keeps getting blocked.
  • Great writer. You document what you changed and why, so the team learns.
  • Self-directed. You find the next problem without being told.
  • Fluent in English, written and spoken.

Required experience:

  • Shipped or contributed to a browser-engine patch, fork, or stealth tool (Chromium, Firefox, camoufox, or similar).
  • Understanding of browser fingerprinting and how to spoof it at the implementation level.
  • Hands-on with CDP and headless or headful automation internals.

We’re especially looking for:

  • Familiarity with the Chromium or Firefox build infrastructure and large-scale patch management.
  • TLS and HTTP fingerprinting awareness.
  • Experience running browsers at scale.
  • Contributions to open-source stealth or browser tooling.
