Lead Cloudflare's kernel and systems engineers owning the Linux OS lifecycle

This EM role leads a team of kernel and systems engineers responsible for the end-to-end Linux Kernel and core OS delivery pipeline at Cloudflare, targeting merge-to-production in under 30 days. Requires 5+ years managing engineering teams in low-level systems/kernel development plus deep Linux kernel internals knowledge. A strong prep target for EM interviews centered on kernel engineering, upstream open-source contribution, and reboot-limited production environments.

What this interview tests

Linux Kernel internals leadership (memory management, schedulers, network stack) and code-level credibility
Building a fully automated, low-toil CI/CD pipeline for kernel/OS delivery (merge to production in <30 days)
Upstream open-source engagement and 'minimal patch' philosophy for kernel contributions
Kernel-level debugging and telemetry systems for reboot-limited, non-reproducible production issues
Operational metrics (DORA, time-to-fix, upstream commit volume) to drive team performance
