The opportunity

We are supporting a major secure government programme building modern cloud-native and AI-enabled digital capability within a highly technical AWS environment.

The team are looking for an experienced Senior DevOps Engineer with strong AWS, Terraform and CI/CD experience who is also comfortable working with Python.

This is not a purely infrastructure-support or systems-administration position. The role sits across DevOps automation, cloud engineering and software delivery, with engineers contributing to AWS platform capability, automated deployments, Python tooling and cloud-native services.

The role could suit either:

• An experienced AWS DevOps or Platform Engineer who regularly uses Python for automation, tooling or cloud services.
• A Python Software Engineer with strong hands-on experience across AWS, Terraform, CI/CD and containerised environments.

You do not need to come from a traditional software engineering background, but you must be able to demonstrate meaningful hands-on Python experience beyond very basic scripting.

What you’ll be doing

• Designing, building and automating secure AWS cloud environments.
• Developing Infrastructure as Code using Terraform.
• Building and improving CI/CD and automated deployment pipelines.
• Using Python to develop automation, engineering tooling and cloud-native components.
• Supporting the deployment and operation of Python services, APIs and backend applications.
• Working with serverless, microservices and event-driven AWS architectures.
• Building and supporting Docker-based and containerised services.
• Improving the reliability, scalability and resilience of cloud-hosted systems.
• Troubleshooting application, deployment and infrastructure issues.
• Working closely with software, platform, cloud and security engineers.
• Contributing to technical design, engineering standards and delivery quality.
• Operating within Agile engineering teams delivering secure digital services.

Essential experience

• Current active SC, enhanced SC or DV clearance.
• Strong hands-on AWS cloud engineering experience.
• Terraform and Infrastructure as Code.
• CI/CD pipeline development and deployment automation.
• Commercial Python experience across automation, tooling, scripting or application development.
• Docker and containerised environments.
• Experience supporting cloud-native applications, APIs, microservices or event-driven services.
• Git-based development and deployment workflows.
• Experience with tools such as GitHub Actions, GitLab CI or Jenkins.
• Experience working within Agile engineering teams.

Particularly relevant AWS experience

Experience across some of the following would be highly beneficial:

• AWS Lambda
• ECS or EKS
• API Gateway
• SNS and SQS
• EventBridge
• IAM
• CloudWatch
• Serverless and event-driven architectures

Desirable experience

• Stronger Python backend development using FastAPI or Flask.
• Kubernetes or Amazon EKS.
• DevSecOps and secure-by-design engineering.
• Observability, monitoring and automated alerting.
• <
• REST APIs and distributed systems.
• Ansible, CloudFormation or AWS CDK.
• AI or LLM integration.
• Previous delivery within government, defence or another highly regulated environment.
• AWS certifications.

The environment

This is a modern, fast-moving and highly collaborative engineering environment. The team work across software engineering, DevOps, platform engineering and cloud automation, with a strong focus on practical delivery, automation and engineering quality.

It is an excellent opportunity for a cleared DevOps or Platform Engineer who wants to work closer to application delivery, or a Python engineer who enjoys operating across both code and cloud infrastructure.

Clearance requirement

Applicants must already hold active SC, enhanced SC or DV clearance . Unfortunately, candidates who are only eligible for clearance or whose clearance has expired cannot be considered.
