About the Role:
You will own the day-to-day reliability of our multi-region NVIDIA DGX cloud. Your charter: keep every host, hypervisor and Kubernetes node battle-hardened so that large-language-model training runs for weeks without a hiccup and real-time inference always returns in milliseconds—whether the workload lives on-prem or bursts to one of several public-cloud providers.
Key Responsibilities:
-
Host & firmware hardening — flash, validate and auto-baseline BIOS, BMC, network-interface and GPU firmware for DGX H100/H200 nodes.
-
Virtualisation & container runtime — run KVM or ESXi at scale, expose VMs to Kubernetes via KubeVirt/Kata Containers, and tune vGPU passthrough, SR-IOV and NUMA pinning for maximum GPU utilisation.
-
Kubernetes SRE — upgrade clusters with zero guest interruption, manage etcd quorum, tune kube-scheduler for GPU topology-aware placement, and operate service meshes (Istio or Ambient Cilium) for gRPC-heavy AI micro-services.
-
High-speed networks — design and troubleshoot 200/400 Gb InfiniBand or RoCE v2 fabrics; enforce network policies with Cilium eBPF and optimise RDMA flows for multi-tenant isolation.
-
Data-resilience flows — implement Velero- or Restic-based backup, cross-AZ snapshot orchestration and quarterly disaster-recovery drills covering control-plane, metadata and model artefacts.
-
Automation first — write Go or Python to drive Terraform, Ansible and Argo CD pipelines; integrate with internal provisioning tool “Void” for end-to-end, push-button node builds.
-
Operational leadership — rotate on high-severity incident duty, publish RCA documents within 72 hours and mentor L5 engineers in Kubernetes, GPU and RDMA debugging.
Qualifications:
-
8 + years of production Linux, networking and virtualisation.
-
Active CKA and CKS (or equivalent open-source contributions proving the same depth).
-
At least one year running NVIDIA DGX or comparable GPU clusters at ≥ 1 PFLOP scale.
-
Deep KVM or ESXi expertise including vMotion/live-migration, SR-IOV NICs and vGPU scheduling.
-
Hands-on InfiniBand/RDMA troubleshooting with perfquery, ibstat, nvidia-smi nvlink topology, TCPDump on RDMA (diag mode).
-
Professional-level cloud networking or architect certification (AWS Advanced Networking Specialty, Azure Network Engineer Expert, Google PCNE, etc.).
