Clearance Required: Active SC Clearance (Mandatory)

The Opportunity

We're seeking an experienced Lead DevOps Engineer to join a high-performing team delivering mission-critical solutions across Defence, National Security, and Government environments.

This is an exciting opportunity to work on complex, high-impact programmes where security, reliability, and innovation are paramount. You'll play a leading role in designing, building, and operating secure cloud and data platforms, helping customers modernise their technology estates and unlock greater value from their data.

Working alongside talented engineers and architects, you'll leverage modern DevSecOps practices, cloud-native technologies, automation, and Infrastructure-as-Code to deliver scalable, resilient, and secure solutions. In addition to providing hands‑on technical leadership, you'll mentor engineers, champion best practices, and help shape the future direction of engineering delivery.

Please note: Active SC Clearance is an essential requirement for this position. Due to the nature of the work, candidates must already hold current and active SC Clearance. Unfortunately, sponsorship or clearance applications cannot be supported for this role.

• Build and operate secure cloud environments supporting data platforms and batch and real‑time analytical workloads.
• Contribute to the development and enhancement of automated testing frameworks, ensuring quality throughout the software development lifecycle.
• Maintain and optimise deployment scripts, automation tooling, and engineering processes in line with evolving requirements.
• Support the setup, maintenance, and optimisation of development, test, and production environments.
• Provide production support through incident investigation, troubleshooting, root cause analysis, and resolution.
• Perform ongoing application and platform maintenance to ensure operational stability, performance, and resilience.
• Conduct gap analysis and identify improvements, recommending practical and scalable technical solutions.
• Support contingency planning and disaster recovery activities, including backup and restoration strategies.
• Produce and maintain technical documentation covering systems, deployments, and operational procedures.
• Mentor and support engineers across the team, fostering collaboration, technical excellence, and continuous improvement.
