What You'll Do: The Systems Engineering team owns the host software stack that turns a freshly provisioned bare-metal machine into a healthy Kubernetes worker — the OS image, kernel and drivers, and the hardware and firmware beneath them. We build and operate the test framework that qualifies every server image on real physical hardware before it reaches one of the largest GPU fleets in the world, and we're extending that framework into HPC verification, Slurm-on-Kubernetes, and further down the stack. About the role: As a Senior Software Engineer on the Systems Engineering team, you will own and evolve our test framework — in-house, Kubernetes-native system that qualifies host images and infrastructure on real hardware. You'll harden the framework's core, broaden what it can validate, and keep CI fast and trustworthy at fleet scale, where a 0.1% failure rate is thousands of GPUs. Day-to-day, you'll build test harnesses and CI infrastructure, extend coverage into HPC and Slurm-on-Kubernetes (SUNK), and shape the abstractions other engineers use to add their own tests without reinventing the framework underneath them. Some of what you'll work on: Own and extend the test framework — that pins to a real host, boots the configuration under test, runs a containerized check, validates it, and records a structured result. Broaden what the framework qualifies: HPC and fabric verification, Slurm-on-Kubernetes (SUNK), and further down the stack into firm…
