• A clear grasp of CI/CD concepts, and the ability to translate them into maintainable automation code.
• Hands-on experience with container technologies like Docker and orchestration platforms such as Kubernetes, EKS, AKS or GKE.
• Good working knowledge of Linux and/or Windows server administration, especially within automated or highly optimised environments.
• Confident use of Git version control, including branching strategies, pull requests and collaborative workflows.
• In-depth knowledge of Infrastructure as Code (IaC) principles, lifecycle management and best practices.
• Familiarity with runbook automation and operational orchestration patterns.
• A strong understanding of DevOps and Site Reliability Engineering (SRE) principles-and how they drive resilient, high-performing systems.
• Practical, hands-on skills in scripting and automation languages, enabling you to build solutions that are reliable, repeatable and scalable.
• Excellent troubleshooting and root-cause analysis skills across automated environments.
• Awareness of Agile or ITIL practices, and comfort working in fast-paced, iterative environments.

If you're passionate about automation, motivated by meaningful challenges, and excited to contribute to critical national infrastructure, you'll thrive here.
