About this role

Cloudflare is hiring for a Performance Engineer, Kernel and Memory role. See the official posting for full details.

Requirements

  • Deep expertise in the Linux kernel memory-management subsystem: the page allocator, virtual memory and memory mapping, reclaim, and the locking and concurrency that hold it together.
  • A track record of upstream Linux contribution, ideally including maintainership or sustained work in MM or an adjacent subsystem.
  • Strong systems programming in C, with the judgement to make high-risk changes to shared infrastructure safely.
  • Ability to dive deep into a complex codebase while keeping the fleet-wide picture in mind, and to own a problem and its outcome rather than a single patch.
  • Clear communication with engineers across many teams, since the symptoms of an MM problem usually show up far from the MM code.
