Engineering Manager, Linux Team in London

Available Locations: London, UK

What You’ll Do

• Lead and Mentor: Manage a high‑performing team of kernel and systems engineers, fostering a culture of collaboration‑first and continuous knowledge sharing both internally and with the global open‑source community.
• Own the OS Lifecycle: Oversee the end‑to‑end delivery of the Linux Kernel and core OS components. Your goal is a fully automated continuous‑delivery pipeline that moves from merge to 100% production in less than 30 days.
• Drive Technical Vision: Steer the Cloudflare kernel development roadmap, balancing cutting‑edge features with production stability, security, and performance.
• Upstream Advocacy: Promote a minimal‑patch philosophy by ensuring your team is a top contributor to the Linux Kernel and supporting engineers to become upstream maintainers for critical subsystems.
• Cross‑Functional Collaboration: Act as a consultant to hardware and service teams, helping onboard new hardware and optimize workloads for our OS, while leading a virtual‑team environment that invites any engineer at Cloudflare to contribute to the kernel.
• Innovate Debugging: Tackle seemingly impossible kernel‑level debugging challenges by leading the development of automated systems that collect critical telemetry when a system crashes, even when traditional debuggers cannot run.
• Measure Success: Use DORA metrics and team‑specific capabilities—such as time‑to‑fix a kernel issue and upstream commit volume—to track and improve team impact.

What You’ll Bring

• Systems Leadership: 5+ years of experience managing engineering teams, ideally in low‑level systems, kernel development, or large‑scale infrastructure environments.
• Low‑Level Expertise: A deep understanding of Linux Kernel internals, x86/ARM architecture, and OS design fundamentals, comfortable discussing memory management, schedulers, and network stacks.
• Automation Mindset: Experience building or managing CI/CD pipelines for foundational software and believing that toil is a bug while automation is a feature.
• Open Source Pedigree: A proven track record of engaging with the open‑source community and navigating upstreaming dynamics effectively.
• Operational Empathy: Understanding of the unique challenges of a global reboot‑limited production environment, prioritizing stability, and experience with pre‑production QA and synthetic workload evaluation.
• Strategic Communication: Ability to translate complex kernel‑level obstacles into actionable business insights for stakeholders across the company.
• Resilience: Ability to lead a team through difficult challenges with a pragmatic, solution‑oriented mindset.
