Staff Infrastructure Engineer, Networking (Groq Metal)
Summary
Technical lead for the bare-metal layer of Groq's AI platform: turning thousands of physical servers across data centers into healthy, tenant-assignable Kubernetes nodes. Day to day this means server provisioning, OS/firmware lifecycle, datacenter networking fabric, and the Kubernetes substrate using tools like Metal3, Ironic, Cilium, Terraform, and GitOps.
- Bare-metal lifecycle at scale— automated server bring-up (PXE/iPXE, Metal3, Ironic, kubeadm), OS image lifecycle, BIOS/firmware/BMC fleet management, hardware health telemetry and remediation.
- Datacenter networking fabric— leaf/spine, BGP, ECMP, RoCE, congestion control, tenant traffic isolation, IPAM, switch automation. You'll partner with our networking architects on Spectrum-X-class fabrics that power multi-tenant AI workloads at line rate.
- Kubernetes substrate— the host clusters that run our multi-tenant control plane (Cilium CNI, Karpenter for capacity, GitOps via Flux/Argo, virtual cluster integration). You won't be the K8s app developer, but you'll be the person the K8s app developers trust to keep the floor solid.
- New datacenter bring-up— turn "rack lands on the floor" into "production capacity available to customers" as a repeatable, automated workflow.
- Day-2 operations— partner with DC field staff on hardware faults, maintenance windows, and on-call response. Be the voice of the physical layer in platform design conversations.
- 8+ years in production infrastructure, with at least 3 years owning bare-metal lifecycle at scale.
- Strong in datacenter networking fundamentals: BGP, leaf/spine, MTU, congestion control, fabric debugging.
- Production Kubernetes operations experience — cluster bring-up, CNI internals, fleet upgrades.
- Comfort with infrastructure-as-code (Terraform, Helm) and GitOps.
- Has been on-call for a fleet of physical machines and knows what that costs.
- NVIDIA GPU clusters at scale (H100 / GH200 / GB200 / NVL72) — driver stack, NCCL, NVLink, GPU Operator.
- DPUs (NVIDIA BlueField, AMD Pensando) and offload patterns.
- Spectrum-X / RoCE / InfiniBand fabrics for AI workloads.
- Background in hyperscaler infra, AI cloud (CoreWeave / Crusoe / Lambda / Together), HFT, or HPC.
- Purposeful Hiring: You’re not here by accident, and neither is anyone else. Every teammate is handpicked with intention because who we build what matters.
- Builders Wanted: You’re not just riding the rocket ship, you’re building it. Your work directly shapes the trajectory of our company.
- Mission-Driven Work: We’re here to make a real impact. Our mission fuels everything we do.
- Tackling Hard Problems: If easy isn’t your thing, you’re in the right place. We solve some of the most complex and exciting challenges in our space.
- Excellence Is The Standard: High performance isn’t just encouraged, it’s the baseline. And it’s contagious.
