📋 Description

• Own and evolve the Kubernetes networking architecture for GPU clusters running at multi-thousand-node scale • Design, operate and scale the overlay network - CNI, mesh and VPN topologies (Tailscale, WireGuard), and the gateways that connect control and data planes • Design, operate and scale the L7 gateways/load balancers/tunnels (Envoy, Cloudflare) • Find and eliminate scale ceilings: packet loss under load, control-plane saturation, IP address management exhaustion, and failure modes above a few thousand nodes • Build scale-test environments and validation suites to catch networking regressions before production • Diagnose hard, ambiguous problems across the stack, tracing symptoms in Slurm or training jobs to networking root causes • Partner with cloud and neocloud providers on network topology, requirements and capabilities for new clusters • Provide senior technical judgement to a distributed team in the Cluster Networking domain

🎯 Requirements

• BS/MS in Computer Science, Electrical Engineering or a related field, or equivalent experience • 6+ years of professional experience in systems, network or infrastructure software engineering • Deep command of Kubernetes networking architecture and CNI standards, with production experience operating Calico strongly preferred • Proficiency designing and maintaining modern mesh and VPN networking topologies - Tailscale, WireGuard or equivalent • Strong Linux networking fundamentals: routing, netfilter and iptables/nftables, packet marking, network namespaces, and how these interact with container runtimes • Demonstrated ability to debug distributed network problems at scale - packet capture, tracing, and correlating behaviour across many hosts to find a single root cause • Proficiency in Go, Python, C or a comparable systems language • Clear written and verbal communication, and the ability to work effectively with engineers across multiple time zones • Direct experience architecting and operating massive-scale Kubernetes topologies across thousands of concurrent nodes • Experience with high-performance fabrics in AI or HPC environments - InfiniBand, RoCE, or RDMA over converged networks • Upstream contributions to Calico, Cilium, Tailscale, or Kubernetes networking SIGs • Experience operating networking across multiple public clouds and on-premises environments simultaneously • Familiarity with Slurm or other HPC schedulers running on Kubernetes
