Important This position will not suit someone whose recent experience is predominantly manual testing, UAT coordination or test management. We need a technically hands-on engineer who can work across Python code, APIs, CI/CD pipelines, Terraform, AWS infrastructure and automated testing. ## Description We are supporting a secure central government programme looking for an experienced DevOps Test Automation Engineer/SDET to join a highly technical, cloud-native engineering team. This is not a conventional manual or functional testing role. The team need an engineer who can bridge test automation, quality engineering and DevOps-someone comfortable writing Python, working inside CI/CD pipelines, validating AWS infrastructure and deployments, and testing APIs, microservices and event-driven systems. The wider engineering environment includes Python, AWS, Terraform, Kubernetes/EKS, CI/CD, APIs, microservices and distributed systems. The role You will design and implement automated quality controls throughout the software-development lifecycle, working closely with software engineers, DevOps/platform engineers and other technical specialists. Your responsibilities will include: * Designing and developing Python-based automation frameworks for API, integration, contract, service and web testing. * Embedding automated tests, smoke checks and quality gates into CI/CD pipelines. * Testing AWS-hosted applications, cloud-native services and infrastructure changes. * Validating Terraform deployments, environment configuration and operational readiness. * Testing APIs, microservices, messaging platforms and event-driven integrations. * Working with containerised environments using Docker, Kubernetes and Amazon EKS. * Performing API and contract testing using tools such as Postman, Pact and REST automation libraries. * Testing asynchronous and distributed systems, including Kafka or AWS messaging services. * Diagnosing failures across application code, pipelines, infrastructure, logs and environments. * Supporting functional and non-functional testing across performance, security, resilience and reliability. ## Related Videos - [Hosting a modern justice system](https://www.wearedevelopers.com/videos/332-hosting-a-modern-justice-system) - [From DevOps to Scaled DevOps: How We’re Rebuilding Continuous Delivery as a Platform](https://www.wearedevelopers.com/videos/100018-from-devops-to-scaled-devops-how-we-re-rebuilding-continuous-delivery-as-a-platform) - [Docker Compose: Rediscovered](https://www.wearedevelopers.com/videos/1978-docker-compose-rediscovered) - [Enabling automated 1-click customer deployments with built-in quality and security](https://www.wearedevelopers.com/videos/83-enabling-automated-1-click-customer-deployments-with-built-in-quality-and-security) - [Docker build without Docker](https://www.wearedevelopers.com/videos/100114-docker-build-without-docker) - [DevOps Maturity Check – a way to balance autonomy and alignment](https://www.wearedevelopers.com/videos/58-devops-maturity-check-a-way-to-balance-autonomy-and-alignment) ## Related Articles - [The 8 Best Code Testing Tools](https://www.wearedevelopers.com/magazine/402-the-8-best-code-testing-tools) - [Data Engineer Salary UK](https://www.wearedevelopers.com/magazine/253-data-engineer-salary-uk) - [Fully Remote Software Engineer Jobs](https://www.wearedevelopers.com/magazine/447-fully-remote-software-engineer-jobs) - [Software Engineer Salary London](https://www.wearedevelopers.com/magazine/252-software-engineer-salary-london) - [DevOps Engineer Salary [2023]](https://www.wearedevelopers.com/magazine/203-devops-engineer-salary-2023) - [Fullstack Developer Salary UK](https://www.wearedevelopers.com/magazine/251-fullstack-developer-salary-uk)
