About the role

Senior Software Engineer on the Systems Engineering team responsible for owning and evolving the test framework that qualifies host images and infrastructure on real hardware, with a focus on Kubernetes-native testing, HPC verification, Slurm-on-Kubernetes, and expanding coverage down the stack.

Responsibilities

  • 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 firmware and hardware, building the abstractions that make new coverage easy to add.
  • Keep the pipeline fast, hermetic, and trustworthy — boot consistency, per-host resource locking, and ruthless flaky-test elimination — so engineers trust the signal.
  • Own the results and reporting path end to end: structured test results, storage, dashboards, and the triage surfaces engineers use to turn a red run into a root cause quickly.
  • Explore AI-native testing — LLM-driven log triage, failure classification, and regression detection — as the fleet and test surface grow.
  • Collaborate with firmware, kernel, imaging, and HPC teams to embed testing into their release process.

Qualifications

  • 3+ years of experience building test infrastructure, systems software, or platform tooling at scale, with real ownership of frameworks or automation for low-level software.
  • Fluent in Python, with either proven Rust experience or a strong systems background (Go, C, C++) and a genuine appetite to build in Rust — the framework's core is Rust, and you'll live in it.
  • Comfortable operating in a Kubernetes environment and reasoning about how software is built, containerized, deployed, and tested.
  • Solid Linux systems background — the boot chain, kernel and drivers, low-level debugging — and comfort working close to the hardware.
  • Real testing discipline: you've built automation that proves systems work, and you have strong opinions about flakiness, hermeticity, and signal.
  • Clear communicator who treats the test framework as a product other engineers want to use, not a chore they route around.
