We're looking for a motivated Infrastructure Support Engineer. You'll support a compact but unusually broad infrastructure footprint that supports hardware design, security verification, FPGA-based testing, CI/CD for silicon projects, and collaborative open-source workflows. This is a fantastic opportunity for a junior to mid-level engineer who thrives on learning new technologies quickly and enjoys making incremental improvements in a mission-focused setting. You'll gain hands-on experience across declarative infrastructure, zero-trust networking, hybrid cloud/on-prem Kubernetes, and custom tooling—while contributing directly to the productivity of engineers building foundational open-source silicon. Key Responsibilities Help maintain and troubleshoot our on-prem Kubernetes cluster, powering hardware simulation, verification, and test workloads Support our
