Sr. Chromium Engineer

Our Client, a Digital Media company, is looking for a Senior Chromium Engineer to work remotely in an EST location.
 
Responsibilities:

• Develop and maintain core desktop browser features and UI components built on top of Chromium''s architecture.
• Debug and resolve complex platform-specific issues related to rendering, networking, multi-process architecture, and system integration within the Chromium codebase.
• Use AI coding tools (Claude Code, Codex) to write and maintain high-quality, efficient code — our team does not write code by hand.
• Optimize the browser for performance, memory usage, and responsiveness across desktop platforms.
• Participate in code reviews as applicable, weekly meetings, daily standups and weekly demos (Fridays).

Key projects or initiatives for the role:

• Desktop browser feature development: AI-driven features, custom browser UI, and service integrations
• Performance, stability, and quality improvements across the Desktop app
• Developer tooling, CI/CD, and build system improvements as needed

Success metrics or KPIs for this role:

• Quality and stability of patches — PRs pass CI, don''t regress existing features, and maintain clean separation from upstream
• Feature velocity — shipping user-facing desktop features within our 1-week cycle cadence
• Effective use of AI coding tools — leveraging agents for implementation while providing expert Chromium review and architectural guidance
• Ability to ramp quickly on unfamiliar parts of the codebase (our specific fork, patch system, build pipeline) using AI tools to bridge knowledge gaps   
• PRs shipped per week
• Stability metrics — crash rates, bug count, CI pass rate on desktop builds
• Peer feedback and ability to unblock other engineers on Chromium-related questions

 
Requirements:

• 6+ years of professional software engineering experience
• Strong C++ proficiency (Chromium is ~35M lines of C++)
• Direct experience working in the Chromium codebase — not just "browser experience," but actually building on, patching, or forking Chromium
• Experience maintaining a Chromium fork or downstream browser (e.g., Brave, Vivaldi, Edge, Opera, Arc, or similar)
• Experience with Chromium''s build system (GN/Ninja) and development workflow (depot_tools, gclient)
• Comfort with large codebases (Chromium is one of the largest open-source projects in existence)
• Willingness and ability to use AI coding tools (Claude Code) as the primary development method
• 2+ years working directly in or with Chromium
• Prior experience at a company that ships a Chromium-based browser or embedded WebView product is ideal

 
Why Should You Apply?

• Excellent growth and advancement opportunities
