About the role

CoreWeave runs some of the largest GPU clusters in the world, and the network has a lot to do with how well they perform. As a Senior Specialist Field Engineer for Networking, you'll help customers get the most from the GPU fabric, the front-end network, and the links between data centers. You'll work closely with the Networking product and engineering teams, and what you learn in the field will help shape what they  this role, you will:

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 (Infini Band, 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.

Who You Are :

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 Wire Guard 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.

Preferred Expertise with Infini Band 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 black holing 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.
