About the Team
Cloudflare Browser Isolation runs web content in remote browsers, helping protect users from threats while preserving a responsive browsing experience. Our team builds the Chromium-based browsing engine, remote rendering and streaming technology, and distributed services that manage browser sessions across Cloudflare's global network.
Responsibilities
- Own well-scoped features and improvements from design and implementation through testing, rollout, and production follow-up, with support from experienced teammates.
- Develop and maintain C++ code in our Chromium-based browser, and contribute across distributed services and systems components written in Go, Rust, and TypeScript.
- Debug failures across browser processes, Linux hosts, and distributed services using logs, metrics, traces, and profiling tools.
- Improve session reliability, startup time, interactive latency, and resource efficiency; validate improvements with measurements.
- Write maintainable code, automated tests, and clear design notes; participate in constructive code and design reviews.
- Collaborate with teammates and partner teams, communicate trade-offs and blockers, and incorporate feedback.
- Participate in the team's production on-call rotation after onboarding, and contribute to incident mitigation and follow-up improvements.
Requirements
- Experience delivering and maintaining production software, with practical C++ proficiency and an understanding of memory ownership, resource lifetimes, and concurrency.
- Linux/UNIX fundamentals, including processes, threads, networking, and tools for diagnosing system behavior.
- Working knowledge of data structures, algorithms, and software design.
- Experience developing or operating distributed systems, with an understanding of service-to-service communication, timeouts, retries, partial failure, and basic consistency trade-offs.
- Ability to navigate an unfamiliar codebase, break a defined problem into deliverable steps, and test correctness and failure cases.
- A systematic approach to debugging and performance analysis, using evidence to form and test hypotheses.
- Clear communication, collaborative problem-solving, and a willingness to learn Rust, Go, TypeScript, and the rest of our stack.
Bonus Points
- Browser engines, Chromium, browser sandboxing, or security-sensitive systems.
- Low-latency streaming, graphics, remote computing, or other real-time systems.
- Container and workload orchestration, including Nomad or Kubernetes, and service discovery.
- Experience using Rust for systems programming or distributed services.
- Go or TypeScript; WebRTC, Skia, WebAssembly, or WebGL.
- Production observability, capacity planning, incident response, or build and release infrastructure.
