Senior Specialist Field Engineer - Networking

What they’re looking for

• B.S. in Computer Science or a related technical discipline, or equivalent experience.
• 7+ years building or operating large-scale networks, as a network, systems, or software engineer, or in a deeply technical networking-focused field role.
• Solid working knowledge of network protocols such as BGP, VXLAN/EVPN, and DNS.
• Deep understanding of Kubernetes networking, including CNIs such as Cilium or Calico.
• Expertise in cloud connectivity: VPCs, peering, dedicated interconnects, and VPNs such as WireGuard or Tailscale, and the trade-offs between them.
• Very comfortable going below the tooling to analyze packet captures, kernel routing tables, interface and fabric counters.
• You explain technical problems clearly to engineers and executives, and you build trust with customers.
• Expertise with InfiniBand and RoCE, including fabric diagnostics, subnet management, and partition-based tenant isolation.
• Experience with NVIDIA GPUs, especially GB200/GB300 platforms.
• First-principles debugging through the Linux kernel network stack, eBPF, FRR, and OVS.
• Diagnosing distributed failures across hundreds of nodes, such as ECMP blackholing across fabric planes.
• Large Direct Connect designs: per-VPC BGP sessions, prefix strategy, and cloud provider limits.
• Contributions to networking open source (kernel, FRR, Cilium, OVS) or published work on fabric design or network debugging.
• Wondering if you’re a good fit?
