Engineering Manager

What you'll do

• Lead a team of senior systems engineers working in C++ and Rust on one of the most performance-critical and security-sensitive services at Cloudflare.
• Drive major infrastructure initiatives — migrating legacy systems, redesigning core abstractions, and laying the groundwork for next-generation runtime architecture that will define the platform for years to come.
• Own reliability and release safety for a service handling tens of millions of requests per second. Improve release processes, invest in health monitoring and automated rollback, and ensure the team can ship changes confidently at scale.
• Make hard prioritisation calls between new feature work that unblocks customers and the ongoing investment in foundations, security, and developer velocity that the team needs to stay healthy long-term.
• Partner closely with adjacent teams across the Developer Platform to ensure the runtime supports the broader product roadmap — including compute, storage, networking, and observability teams.
• Grow and develop the team: Hire strong systems engineers, set clear expectations, provide technical mentorship, and create an environment where people do their best work.

Requirements

• Track record of leading teams that operate large-scale, low-latency distributed systems.
• Balance the urgency of production with the patience required for foundational improvement.
• Technically credible enough to evaluate architectural proposals, weigh tradeoffs in C++/Rust systems, and earn the respect of a deeply technical team.
• Strong enough manager to build a healthy, high-performing engineering culture.
• Experience leading a team.
• Comfortable leading and hiring a team that builds low level distributed systems.
• Excel at planning, creating teams and overseeing execution to meet commitments and deliver with predictability.
• Comfortable building developer-loved APIs that scale.
• Demonstrate a track record of leading a team including hiring, on-boarding, and professional development. Inspire your team to reach higher. As good at explaining “why” as “how”.
• Experience implementing tools, process, internal instrumentation, methodologies and resolving blockages.
• At least 4 years of recent professional experience with C++ or Rust.
• Solid understanding of computer science fundamentals including data structures, algorithms, and object-oriented or functional design.
• Deep understanding of the web and technologies such as web browsers, HTTP, JavaScript and WebAssembly.
• Strong understanding of Linux systems programming, process models, and networking.

Nice-to-haves

• Experience building high performance distributed systems.
• Experience working with cloud platforms, especially server-less platforms.
• Experience with the internals of JS engines such as V8, SpiderMonkey, or JavaScriptCore.
• Experience with standalone WebAssembly runtimes such as Wasmtime, Wasmer, Lucet, etc.
• Deep Linux/UNIX systems, kernel, or networking knowledge.
• Contributions to large open source projects.
• Experience working in low-latency real time environments such as game streaming, game engine architecture, high frequency trading, payment systems.
• Experience debugging, optimizing and identifying failure modes in a large-scale Linux-based distributed system.
