Senior Systems Engineer, Test Frameworks & Validation Platform

CoreWeave is The Essential Cloud for AI. As a Senior Systems Engineer on the Systems Engineering team, you will own and evolve our test framework, a Kubernetes-native system that qualifies host images and infrastructure on real hardware.

Responsibilities:

• Own and extend the test framework that qualifies host images and infrastructure on real hardware
• Broaden what the framework qualifies, including HPC and fabric verification, Slurm-on-Kubernetes, and further down the stack into firmware and hardware
• Keep the pipeline fast, hermetic, and trustworthy, ensuring engineers trust the signal
• Own the results and reporting path end to end, including structured test results, storage, dashboards, and triage surfaces
• Explore AI-native testing, including LLM-driven log triage, failure classification, and regression detection
• Collaborate with firmware, kernel, imaging, and HPC teams to embed testing into their release process

Requirements:

• 3+ years of experience building test infrastructure, systems software, or platform tooling at scale
• Fluent in Python, with either proven Rust experience or a strong systems background
• Comfortable operating in a Kubernetes environment and reasoning about software deployment and testing
• Solid Linux systems background, including boot chain, kernel and drivers, and low-level debugging
• Real testing discipline, with strong opinions about flakiness, hermeticity, and signal
• Clear communicator who treats the test framework as a product other engineers want to use

Preferred:

• Rust and Kubernetes-native workflow orchestration experience
• HPC or large-cluster experience, including InfiniBand/RoCE, GPU/accelerator validation, or performance-regression frameworks
• Slurm or Slurm-on-Kubernetes experience
• Firmware or lower-level hardware validation experience
• Applying LLMs to test workflows, including triage, failure classification, and flaky-test detection
