  LB or BGP-based solutions.
• Develop custom Kubernetes controllers/operators to manage networking resources such as IP pools, VLAN assignments, and DNS records.
• Automate network provisioning and reconciliation across hybrid hardware environments.
• Ensure CRDs and operators integrate cleanly with Git Ops workflows.
• Integrate cluster networking with upstream DNS servers for internal and external resolution.
• Manage IP address allocation across nodes, pods, and external interfaces.
• Implement IPAM solutions for hybrid and multi-tenant environments.
• Bridge cluster networking with underlay/overlay networks including VLANs and BGP.
• Ensure external VLANs can be safely consumed by workloads within K3s clusters.
• Collaborate with hardware teams on NIC configuration, firmware support, and consistent network naming.
• Implement network policies, encryption, and isolation across multiple CNIs.
• Integrate observability tools such as Cilium Hubble, Prometheus, and custom metrics.
• Ensure network paths comply with security and compliance requirements.
• Work with Dev Ops, SRE, and Hardware Engineering teams to align networking design with PaaS needs.
• Document networking architecture, CRDs, controllers, and operational runbooks.
• Provide knowledge transfer on advanced networking topics including Multus, VLANs, and bare-metal load balancing.

• Bachelor's degree in Computer Science, Computer Engineering, Software Engineering, or equivalent experience.
• 15+ years of software engineering experience with strong focus on Kubernetes/K3s networking.
• Hands‑on experience with Multus CNI for multi‑network attachment definitions.
• Strong knowledge of Cilium or Calico for advanced networking, security, and observability.
• Experience with bare‑metal load balancers such as Metal
  
  LB and BGP.
• Proficiency in developing Kubernetes controllers/operators in Go (controller‑runtime, Kubebuilder, Operator SDK).
• Experience with IP address management (IPAM), DHCP, and DNS integration.
• Experience configuring VLANs and bridging external networks into Kubernetes.
