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.
