We’d love to see it). • Deep knowledge of namespaces, cgroups, or KVM. • Python scripting for tooling, automation, or test harnesses. • Familiarity with DevOps pipelines involving container tech or kernel builds. • You can communicate your ideas clearly in English, whether it's in a code review or a conference talk.
