About the role

Senior Specialist Field Engineer role focusing on networking within CoreWeave's CX organization, driving design, troubleshooting, and customer collaboration to optimize GPU fabric, front-end network, and inter-data center links across multi-cloud/hybrid environments.

Responsibilities

  • Design network architecture for complex customers (multi-cloud, multi-region, hybrid Kubernetes, bare metal, Direct Connect), including how it fails and what each failure affects.
  • Troubleshoot problems that span many nodes and VPCs, from the Linux kernel and the CNI up through the data-center fabric and HPC interconnects (InfiniBand, RoCE).
  • Find where the product falls short for real workloads and work the gap through with engineering, as an extended member of the Networking team.
  • Lead customer technical overviews, proofs of concept, and customer workshops, with occasional travel.

Qualifications

  • 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.
