Infrastructure Support Engineer - Cambridge in Eastbourne

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 Nebula overlay network as we build toward a robust zero-trust model across distributed engineering teams
Operate and enhance self-hosted GitHub Actions runners, including an FPGA test rig that handles real hardware requests from CI workflows
Maintain and gradually improve our Python-based internal tooling (used daily by hardware and software engineers) — refactoring for maintainability, adding features, and applying better software practices where it adds value
Manage NixOS servers through declarative configurations for reproducible, reliable deployments
Provision and manage Google Cloud resources (VMs, GKE-based runners, storage, networking) using Terraform / OpenTofu
Monitor system health and respond to alerts
Collaborate with hardware engineers, security specialists, and open-source contributors to debug issues spanning CI pipelines, FPGA rigs, cloud environments, and internal scripts
Document setups, workflows, and lessons learned to help onboard new team members and partners
