• Strong understanding of Kubernetes internals including CRDs reconciliation loops custom resources owner references parent-child relationships finalizers and controller lifecycle management.
• Experience developing or operating Kubernetes-based systems at production scale beyond basic cluster administration or application deployment.
• Strong Linux systems knowledge including processes namespaces cgroups permissions memory management and process lifecycle.
• Strong understanding of TCP/IP and Linux networking including network namespaces sockets iptables/netfilter and node-level networking.
• Good understanding of containers and container runtime concepts including OCI CRI container lifecycle runtime classes and node-level troubleshooting.
• Ability to diagnose complex issues across Kubernetes containers Linux nodes and networking layers.
• Strong software engineering fundamentals including concurrency distributed systems reliability observability testing and production troubleshooting.

Preferred Qualification:

• Experience with Rust or C/C for systems-level development.
• Hands-on experience with gVisor Firecracker/microVMs WASM runtimes or other sandboxing and workload-isolation technologies.
• Experience building multi-tenant Kubernetes infrastructure or systems requiring strong workload and namespace isolation.
• Knowledge of Linux kernel interfaces eBPF netlink syscalls or kernel-level networking.
• Experience with SPIFFE/SPIRE workload identity zero-trust networking or security infrastructure.
• Experience building Kubernetes infrastructure involving RuntimeClass custom schedulers admission controllers webhooks or container runtimes.
• Experience with KMS/secrets management secure credential handling or infrastructure-level security.
• Experience developing systems for large-scale distributed or regulated environments where security reliability and auditability are critical.
• Contributions to Kubernetes cloud-native systems networking or security-focused open-source projects.
