The Kubernetes Network developing Engineer will focus on networking for K3s clusters deployed across hybrid architectures (x86, ARM, accelerators). The role involves designing, implementing, and maintaining cluster networking that integrates with external systems. This includes writing Kubernetes controllers, managing IP address allocation, configuring VLANs outside of K3s and exposing them inside, extending networking with Multus CNI, and ensuring clusters support advanced CNI (Cilium/Calico) and bare-metal load balancing.

The engineer ensures application and infrastructure networking is reliable, scalable, and secure.

• Architect and implement networking for hybrid K3s clusters.
• Configure and optimize CNIs (Multus, Cilium, Calico) for multi-network scenarios.
• Enable VLAN-backed networks, SR-IOV, and multi-interface workloads.
• Deploy and manage bare-metal load balancers (Metal
  
  LB, BGP).
• Build custom Kubernetes controllers/operators in Go for declarative networking.
• Automate IPAM, DNS integration, and network provisioning across hybrid environments.
• Ensure seamless Git Ops integration with CRDs and controllers.
• Implement network policies, encryption, and observability (Cilium Hubble, Prometheus).
• Collaborate with Dev Ops, SRE, and hardware teams to align with platform needs.
• Document architecture, runbooks, and provide internal knowledge transfer.

• Deep expertise in Kubernetes/K3s networking and CNIs.
• Hands‑on experience with Multus, Cilium, Calico, and Metal
  
  LB.
• Proficiency in Linux networking (netlink, iproute2, eBPF).
• Experience with IPAM, VLAN bridging, DHCP/DNS integration.
• Security‑first mindset: RBAC, network policies, encryption.
• Familiarity with service mesh (Istio, Linkerd) and high‑performance networking (SR‑IOV, DPDK).
• Contributions to Kubernetes networking or CNI projects.

• Flexible work
• Healthcare including dental, vision, mental health, and well‑being programs
• Financial well‑being programs such as 401(k) and Employee Share Ownership Plan
• Paid time off and paid holidays
• Paid parental leave
• Family building benefits like adoption assistance, surrogacy, and cryopreservation
• Social well‑being benefits like subsidized back‑up child/elder care and tutoring
• Mentoring, coaching and learning programs
• Employee Resource Groups
