Senior Systems Engineer Kernel Automation & Validation

CoreWeave is seeking a specialized Kernel Automation Engineer to join our HAVOCK this role you will be the architect of our validation infrastructure. You wont just run tests; you will design the framework that ensures stability across the entire vertical stackfrom Firmware to Kernel to NCCL to Slurm.

We need an engineer who understands that a kernel is only as good as the workloads it supports. You will build the CI/CD pipelines and hardware-in-the-loop test harnesses that validate our custom Linux builds against next-generation GPUs high-speed interconnects and AI schedulers.

Our Teams Stack:

Languages: Python (expert level) Go Bash C
CI/CD & Automation: GitHub Actions Jenkins Ansible Terraform ArgoCD
Validation Tools: LAVA (Linaro) LabGrid kselftest Pytest Syzkaller
The Stack: BIOS/BMC Firmware Linux Kernel OFED/RDMA drivers NCCL Slurm
Hardware: Bare metal provisioning (PXE IPMI) NVIDIA GPUs ConnectX

Focus Areas:

End-to-End Test Framework: building a unified test harness that triggers validation from low-level firmware up to high-level Slurm job scheduling.
Hardware-in-the-Loop: Managing and automating a fleet of bare-metal DUTs (Device Under Test) for kernel regression testing.
Performance Validation: Automating benchmarks for NCCL (GPU-to-GPU communication) and RDMA to catch latency regressions before production.
Build Pipeline Evolution: Refactoring the Havock build system to allow any engineer to spin up a custom kernel and test it on real hardware via CLI.
Firmware/Driver Interop: Automating matrix testing between different Kernel versions NVIDIA Drivers and NIC Firmware.

Responsibilities:

Design and implement a full-stack validation pipeline that ensures a kernel change doesnt break NCCL rings or Slurm scheduling logic.
Develop a CLI tool (Go/Python) that allows kernel engineers to launch ad-hoc test runs on specific hardware SKUs.
Automate the provisioning of test nodes including BIOS/BMC configuration and firmware flashing.
Integrate standard kernel tests (LTP kselftest blktests) into a modern CI/CD workflow.
Write Glue code to connect low-level kernel outputs (dmesg serial logs) to high-level reporting dashboards.

Requirements:

5 years of experience in Test Automation Release Engineering or Systems Development.
Strong Python/Go skills: Ability to write complex test frameworks and CLI tools (beyond simple scripting).
The Vertical Perspective: Experience debugging or testing interactions between Firmware Kernel and Userspace.
CI/CD Expertise: Experience building pipelines that manage hardware resources (not just software builds).
HPC Knowledge: Familiarity with Slurm (job scheduling) MPI or NCCL (collective communications).
Experience with bare-metal provisioning (PXE iPXE Kickstart).

Nice-to-haves:

Experience testing RDMA/InfiniBand networks.
Familiarity with NVIDIA GPU architecture and the CUDA ecosystem.
Experience writing Reproducers for kernel bugs in C.
Knowledge of PyTorch distributed training flows.
