Job summary

NVIDIA in Austin, TX is seeking a Senior Networking Engineer to own the Kubernetes networking architecture for GPU clusters at multi-thousand-node scale. You will design, operate, and scale overlay networks and gateways across clouds.

Bring 6+ years in systems or networks, deep Kubernetes/CNI expertise (Calico preferred), and strong Go/Python/C skills. You will debug complex, distributed networks and collaborate across time zones. Equity and benefits are included.

Qualifications

• 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.

Responsibilities

• 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 visible only at scale.
• Build scale-test environments and validation suites to catch networking regressions before they reach production.
