# GPU Infrastructure Engineer / HPC Engineer

Build and operate large?scale GPU compute pods to deliver predictable, high?throughput, low?latency training and inference services across 10K GPU cluster. Roles & Responsibilities Implementation Stand up multi?pod GPU clusters (rack/power/cooling layouts; TOR/leaf connectivity; IB/Ethernet host configs). Implement GPU partitioning (MIG/vGPU profiles) and quota policies for multi?tenant environments. Integrate cluster schedulers (Slurm/Kubernetes) with GPU device plugins, node feature discovery, and accounting/quotas. Operations Own day?2 operations across firmware/driver/DCGM/NVML lifecycles; execute change windows with zero/low downtime. Capacity planning (GPU/CPU/Memory/NIC) and bin?packing strategies for heterogeneous GPU SKUs. Performance & Optimization Tune NCCL/UCX, GPU clocks/persistence, GPU Direct Storage, NUMA/locality, and CUDA runtime parameters. Drive benchmarking and acceptance (HPL, HPL?AI, MLPerf?like internal suites); track perf regressions with SLOs. Reliability & Incident Lead P0/P1 incident response for GPU, CUDA, or scheduler issues; perform root?cause and preventative actions. Act as the primary technical lead during production outages, coordinating cross
