Principal Engineer - Perf and Benchmarking

AI summary of the role

Principal Engineer to lead CoreWeave's Benchmarking & Performance team, owning a planet-scale performance data warehouse and driving industry-leading MLPerf submissions.

What you’ll do

  • Define the multi-year benchmarking strategy and roadmap; prioritize models/workloads and hardware tiers.
  • Lead end-to-end MLPerf Inference and Training submissions: workload selection, cluster planning, runbooks, audits, and result publication.
  • Design a Kubernetes-native, repeatable benchmarking service that exercises CoreWeave stacks across SUNK, Kueue, and Kubeflow pipelines.
  • Build CI/CD pipelines and K8s controllers/operators to schedule benchmarks at scale; integrate with observability stacks and results warehouses.

What you’ll bring

  • 10+ years building distributed systems or HPC/cloud services, with deep expertise on large-scale ML training or similar high-performance workloads.
  • Proven track record of architecting or building planet-scale data systems (e.g., telemetry platforms, observability stacks, cloud data warehouses, large-scale OLAP engines).
  • Deep understanding of GPU performance (CUDA, NCCL, RDMA, NVLink/PCIe, memory bandwidth), model-server stacks (Triton, vLLM, TensorRT-LLM, TorchServe), and distributed training frameworks (PyTorch FSDP/DeepSpeed/Megatron-LM).
  • Proficient with Kubernetes and ML control planes; familiarity with SUNK, Kueue, and Kubeflow in production environments.
