This vacancy is for experienced Release/QA Engineers who can take ownership of the full validation-to-release lifecycle. You should demonstrate practical expertise across several of the areas listed and a proven track record of building reliable, automated, and auditable release processes in complex engineering environments. ## Description Our Capability Development team delivers bespoke, high-assurance software for clients in the Cyber Security domain. We engineer resilient systems ranging from rigorously assured products to rapid cyber solutions and blended operational platforms. Common to all is our commitment to technically led decisions, architectural clarity, and delivering software that operates reliably in high-stakes environments. To support this mission, we are seeking a Release Engineer to own the intersection of quality assurance and release delivery. You will be responsible for designing, automating, and governing the processes that validate and ship code from commit to production, ensuring every release is thoroughly tested, auditable, and operationally resilient. This role sits at the heart of our engineering lifecycle, bridging test strategy, quality gates, and release management to maintain engineering rigour without sacrificing delivery speed. Ideally, you will hold an active Security Clearance to join our team. What you'll do: As a core member of our engineering team, you will: * Design and maintain CI/CD pipelines that embed comprehensive automated testing and quality validation directly into the release workflow. * Develop and execute test strategies for new "clean-slate" products and existing core components, aligning QA milestones with release cadences. * Build and maintain automated E2E/UI test suites using modern frameworks such as Cypress and Playwright, integrating them into release validation gates. * Define and enforce release criteria, quality gates, and automated acceptance checks to ensure consistent, risk-managed deployments. * Manage test environments, test data provisioning, and configuration management to support reliable, repeatable release validation. * Drive the defect lifecycle from detection through resolution, collaborating with developers to eliminate regressions and improve test coverage. * Champion shift-left quality practices by participating in design reviews, requirement analysis, and risk-based test planning. * Produce release documentation, traceability matrices, and compliance artefacts to support auditability and smooth client handovers. * Monitor post-release stability and customer feedback, feeding insights back into continuous improvement of both QA and release processes. ## Related Videos - [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) - [The Road to MLOps: How Verivox Transitioned to AWS](https://www.wearedevelopers.com/videos/1050-the-road-to-mlops-how-verivox-transitioned-to-aws) - [Innovating Developer Tools with AI: Insights from GitHub Next](https://www.wearedevelopers.com/videos/1268-innovating-developer-tools-with-ai-insights-from-github-next) - [Improving quality with Agentic AI with Rovo Dev and Xray](https://www.wearedevelopers.com/videos/2005-improving-quality-with-agentic-ai-with-rovo-dev-and-xray) - [Our GitOps approach for deploying an Identity Provider and an API Gateway in a SaaS company](https://www.wearedevelopers.com/videos/776-our-gitops-approach-for-deploying-an-identity-provider-and-an-api-gateway-in-a-saas-company) - [Bringing AI Model Testing and Prompt Management to Your Codebase with GitHub Models](https://www.wearedevelopers.com/videos/1536-bringing-ai-model-testing-and-prompt-management-to-your-codebase-with-github-models) ## Related Articles - [The 8 Best Code Testing Tools](https://www.wearedevelopers.com/magazine/402-the-8-best-code-testing-tools) - [Dev Digest 121 - AI goes offline](https://www.wearedevelopers.com/magazine/456-dev-digest-121-ai-goes-offline) - [What’s the Difference between a Junior, Mid, and Senior Developer?](https://www.wearedevelopers.com/magazine/238-what-s-the-difference-between-a-junior-mid-and-senior-developer) - [The 12 Best Jobs for Software Engineers](https://www.wearedevelopers.com/magazine/401-the-12-best-jobs-for-software-engineers) - [Dev Digest 120 - Apple and peers](https://www.wearedevelopers.com/magazine/455-dev-digest-120-apple-and-peers) - [Where To Find Software Engineering Jobs](https://www.wearedevelopers.com/magazine/396-where-to-find-software-engineering-jobs)
