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 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.
Who You Are
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.
Preferred
Rust and Kubernetes-native workflow orchestration (e.g., Argo Workflows) experience.
HPC or large-cluster experience — InfiniBand/RoCE, GPU/accelerator validation, or performance-regression frameworks.
Slurm or Slurm-on-Kubernetes (SUNK) experience.
Firmware or lower-level hardware validation experience.
Applying LLMs to test workflows — triage, failure classification, flaky-test detection.
Contributions to open-source test frameworks, Rust crates, or systems projects.
