• Enable VLAN-backed networks, SR-IOV, and multi-interface workloads.
• Deploy and manage bare-metal load balancers (MetalLB, BGP).
• Build custom Kubernetes controllers/operators in Go for declarative networking.
• Automate IPAM, DNS integration, and network provisioning across hybrid environments.
• Ensure seamless GitOps integration with CRDs and controllers.
• Implement network policies, encryption, and observability (Cilium Hubble, Prometheus).
• Collaborate with DevOps, SRE, and hardware teams to align with platform needs.
• Document architecture, runbooks, and provide internal knowledge transfer.

Your skills and experience

• Deep expertise in Kubernetes/K3s networking and CNIs.
• Hands-on experience with Multus, Cilium, Calico, and MetalLB.
• Strong Go development skills (Kubebuilder, Operator SDK).
• Proficiency in Linux networking (netlink, iproute2, eBPF).
• Experience with IPAM, VLAN bridging, DHCP/DNS integration.
• Security-first mindset: RBAC, network policies, encryption.
