Modify and extend Chromium and WebKit source code to enable advanced research and large-scale data extraction. Build, debug, and reverse-engineer browser internals and protocols across Windows, Linux, and macOS.
We are seeking a highly experienced Senior C++ Engineer to join Bright Data's browser research team, working at the intersection of browser engineering, systems programming, and data extraction — modifying and extending Chromium/WebKit to unlock new capabilities for research and large-scale data collection.
Responsibilities
- Modify and extend Chromium/WebKit source code for research and data extraction use cases
- Build, debug, and reverse-engineer browser engines, internals, and protocols (CDP, DevTools, networking stack) across platforms (Windows, Linux, macOS)
- Customize, patch, and rebase a Chromium fork; track and merge upstream changes
- Collaborate with engineers, researchers, and product teams to rapidly prototype and ship high-quality changes
Requirements
- 5+ years of hands-on C++ (C++17/20); ability to navigate large codebases and make precise, targeted changes fast
- Strong understanding of software architecture in large-scale, cross-platform systems
- Deep knowledge of web protocols and browser internals: HTTP/2/3, TLS, CDP, DOM, JavaScript engines
- Experience with security research, reverse engineering, or browser automation (significant advantage)
- Open-source contributions, especially browser- or devtools-related (significant advantage)
- Chromium (significant advantage)
- Build tools: depot_tools, GN/Ninja/Siso; architecture: multi-process model, Blink/V8, sandbox, Crashpad
- Patch/rebase management for forks; resolving large conflicting merges
- Debugging & Tooling: Visual Studio, WinDbg, ETW/xperf, ProcMon; crash dump triage across processes
- Nice to have: Linux containers (Docker, containerd, LXC); CI/CD; security hygiene (sandbox, AppContainer, mitigation policies); basic Node.js/JavaScript
