What you'll do
- Deliver scoped features from design through testing, rollout, and production follow-up; develop Chromium and distributed-systems code.

- Write maintainable code, tests, and design notes; collaborate in reviews and participate in on-call after onboarding.
What they ask for
- Practical C++ proficiency, including understanding memory ownership, resource lifetimes, and concurrency.
- Linux/UNIX fundamentals, including processes, threads, networking, and system-diagnostic tools.
- Working knowledge of data structures, algorithms, and software design.
- Ability to debug systematically, navigate unfamiliar code, and test correctness and failure cases.
Nice to have
- Experience with browser engines, Chromium, sandboxing, security-sensitive systems, or low-latency streaming and real-time systems.
- Experience with orchestration, Rust, Go, TypeScript, WebRTC, Skia, WebAssembly, WebGL, observability, incident response, or build and release infrastructure.
