RT Consulting is expanding our Defence capability and seeking two experienced SC Cleared DevSecOps Engineers to join a high-impact transformation programme supporting a defence project focused on secure hosting and cloud modernisation roadmaps. These roles sit at the heart of a strategic re-platforming effort, moving from a VMware VCF/Aria estate towards a more scalable and secure GCP (Google Cloud)-aligned environment.

This is meaningful work with purpose, modernising defences digital backbone and enabling operational capability across the Defence landscape.

What You’ll Be Doing

As part of a blended team, you will play a key role in the build, automation, containerisation, and secure deployment of applications and infrastructure in a highly classified environment.

Your responsibilities will include:

• Developing, maintaining, and optimising CI/CD pipelines
• Administering Kubernetes (K8s) clusters and containerisation frameworks
• Supporting migration and integration of services into a GCP-aligned architecture
• Delivering automation via IaC tools (Terraform, Ansible, scripting)
• Supporting secure release and deployment processes
• Working hands-on with defence-owned equipment within structured environments
• Diagnosing issues across cloud, infrastructure, networks, and application layers
• Ensuring security is embedded across the DevSecOps lifecycle

What You’ll Bring

To succeed, you’ll need to be a confident DevSecOps practitioner with strong delivery instincts and the ability to operate effectively in a classified Defence Digital environment.

Essential experience:

• Current SC clearance
• Proven DevSecOps engineering experience within secure or complex environments
• Strong Kubernetes (K8s) and containerisation experience
• Experience with GCP or willingness to operate within a GCP-aligned environment
• Hands-on CI/CD tooling — Jenkins / GitHub Actions / GitLab
• IaC skills (Terraform, CloudFormation, Ansible, or equivalent)
• Solid scripting capability (Python, Bash, etc.)
• Practical understanding of secure-by-design and cloud security practices
• Ability to work on-site for 3 days a week (mandatory)

You’ll be joining a programme where your work directly contributes to capability uplift, resilience, and operational readiness across the Army’s digital estate.

What’s in It for You

• 6-month assignments with high likelihood of extension
• PAYE engagement with competitive rates
• The opportunity to shape defences next-generation digital hosting platform
• Work within a trusted, SC-cleared engineering community
• Strong platform for future work and related pipelines
