• Experience in secure or regulated industries (Defence, Government, Aerospace, etc.)
• Solid grasp of CI/CD, containerisation (Docker/Kubernetes), and cloud or on-premise deployments
• Ability to lead technical discussions, reviews, and deliverables across cross-functional teams
• Familiarity with Agile/Scrum delivery
• Active DV Clearance
