Devops Engineer

Job Title: DevOps Engineer

Location: Bristol or Cambridge, UK

Type: Contract (Inside IR35)

Our client are a global semiconductor company.

Key Responsibilities

• GitHub Adoption & Tooling: Don’t just manage GitHub; build it. Use the GitHub API/GraphQL to develop internal tools, GitHub Apps, and custom Actions that automate governance, security, and repository lifecycle management.
• Cloud‑Native CI/CD: Design and orchestrate scalable build environments using Docker and Kubernetes. You will be responsible for the ‘Self‑Hosted Runner’ architecture, ensuring builds are isolated, reproducible, and fast.
• Linux Systems Programming: Optimize build performance at the system level. You will analyse bottlenecks in the CI pipeline, from CPU/Memory constraints to I/O and interconnect fabric on our Linux‑based build farms.
• Infrastructure as Code (IaC): Use Terraform, Ansible, or Go to manage our global CI infrastructure, ensuring that every piece of the environment is version‑controlled and reproducible.
• Service Orchestration: Build and maintain the ‘middleware’ that connects GitHub to our internal hardware‑in‑the‑loop labs, enabling automated testing on physical silicon.

Required Technical Skills

• Proficiency in Python, Go (Golang), or C/C++. You should be comfortable writing production‑grade code to solve infrastructure problems.
• GitHub Internals: Deep experience with GitHub Enterprise, specifically GitHub Actions, Environments, and API‑based automation.
• Linux Mastery: Strong background in Linux Systems Programming and shell scripting. You understand how the kernel handles resources and how to profile system performance.
• Containerization: Expert‑level knowledge of Docker and Kubernetes (K8s) orchestration for managing ephemeral build agents.
• DevOps Mindset: Experience with Git‑based workflows (Gitflow, Trunk‑based) and a ‘Shift Left’ approach to security and testing.
