Senior Systems Engineer, Test Frameworks & Validation Platform

What Youll 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 were 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. Youll harden the frameworks 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 youll 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 youll 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 frameworks core is Rust and youll 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: youve 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.
