Responsibilities

  • Build and improve Kubernetes-native benchmarking services that measure latency, throughput, jitter, and cost-per-request across CoreWeave's compute stack.
  • Implement and maintain benchmarking workflows for end-to-end MLPerf Training and Inference runs, including workload setup, cluster configuration, runbooks, and result validation.
  • Lead design reviews and drive architecture within the team; decompose multi-service work into clear milestones.
  • Mentor junior engineers; review cross-team designs and elevate coding/testing standards.
  • Help ensure reproducible, well-documented benchmarking processes.

Requirements

  • 5+ years of experience building distributed systems, high-performance computing, or cloud services.
  • Strong coding in Python or Go (C++ a plus) and deep familiarity with networked systems and performance.
  • Hands-on experience with Kubernetes at production scale, CI/CD, and observability stacks (Prometheus, Grafana, OpenTelemetry).
  • Experience with performance-critical GPU systems (CUDA, NCCL, RDMA, NVLink/PCIe, memory bandwidth) and model-serving stacks (llm-d, vLLM, TensorRT-LLM, Megatron-LM).
  • Strong communicator comfortable collaborating with cross-functional teams and external partners.
  • Experience with time-series databases, LSM-based storage engines, or custom data pipelines.
  • Experience running MLPerf submissions or similar large-scale audited benchmarks.
  • Contributions to OSS projects such as llm-d, vLLM or PyTorch.
  • Exposure to benchmarking large GPU fleets or multi-region clusters.
  • Experience with CUDA kernels, NCCL/SHARP, RDMA/NUMA, or GPU interconnect topologies.
  • Why CoreWeave
  • Help shape an industry-defining inference platform that enables teams to deploy generative AI and real-time applications at scale. If optimizing tail latency and delivering reliable model serving excites you, this is the place to build.
