Lead complex systems initiatives for Cloudflare Browser Isolation across Chromium, distributed services, and remote browsing infrastructure. Design and implement C++, Rust, Go, and TypeScript systems; investigate cross-layer performance and reliability issues; improve observability, capacity, rollout safety, and resilience. The role includes architectural decision-making, technical leadership, mentoring, cross-team coordination, incident response, and production on-call participation.

Develop and maintain Chromium-based browser and distributed systems components using C++, Rust, Go, and TypeScript. Own features through design, testing, rollout, and production support; debug browser, Linux, and service failures; improve reliability, latency, startup performance, and resource efficiency. Participate in code reviews, documentation, automated testing, collaboration, and on-call incident response.

Design, build, and operate the Linux-based edge appliance runtime and distributed control plane. Implement secure networking dataplanes (IPsec, MASQUE, eBPF), reliable fleet control and remote lifecycle management, telemetry and diagnostics, and drive product-focused technical leadership from architecture through rollout and incident response.

Develop and maintain Cloudflare’s Zero Trust desktop client for Windows using Rust and platform-native APIs. Build high-performance networking and security capabilities, improve code quality, write thoroughly tested and documented code, debug complex system and network issues, contribute to technical designs, and mentor engineers. The role requires expertise in Windows internals, drivers, networking protocols, VPN technologies, and multithreaded asynchronous programming.

Design, build, and operate globally distributed storage systems; own code from design to release; provision and benchmark storage hardware; model failure domains; build observability, runbooks, and automation; collaborate across teams to ensure reliability, performance, and scalability.

Design and implement foundational layers of next-generation distributed storage and streaming systems. Own code end-to-end, architect consistency models, optimize storage engine performance, design data-centric APIs, and debug complex race conditions, partitions, and infrastructure-level failures. Work across system layers using Rust/C++ and interact with JavaScript/TypeScript as needed.

Lead architecture and implementation of Cloudflare Tunnel systems (client and edge services). Design, code, test, monitor, and scale distributed, secure microservices. Mentor peers, drive roadmap, debug production issues, and collaborate with security, SRE, network engineering, and product teams.

Design, build, and operate Cloudflare's distributed storage and database products (R2 Data Catalog, R2 SQL). Own full lifecycle delivery, architect consistency models, optimize storage engine performance, design APIs, and debug large-scale distributed systems using Rust, TypeScript, Go, C++, and Linux/UNIX.
