When something breaks at the Kubernetes layer — a pod stuck in a mystery state, a cgroup that won't reclaim memory, a scheduler decision that makes no sense — the root cause almost always lives below the abstraction, in the kernel. Our team is the last line of defense: we go down into memory management, scheduling, and namespaces to find out what's actually happening, fix it, and often upstream the fix.</p> <p><strong>About the role:</strong></p> <p>As a Senior Software Engineer on the Systems Engineering team, you will be the kernel expert who traces complex, ambiguous failures in Kubernetes, pods, and containers back to their root cause in the Linux kernel — and fixes them there. You'll live at the boundary between kernel internals (cgroups, namespaces, the scheduler, memory management) and the container/orchestration stack bui
