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.
Desirable Skills
- Hands-on experience building and integrating automated testing frameworks into CI/CD pipelines, with specific proficiency in tooling for UI/E2E validation.
- Strong command of QA methodologies (Black-box, White-box, Regression, Exploratory, and Risk-based testing) and test strategy design.
- Practical experience with CI/CD platforms (e. g., Git Lab CI, Git Hub Actions, Azure Dev Ops, or Jenkins) and embedding automated quality gates.
- Familiarity with test management and defect tracking tools (e. g., Jira/Xray, Test Rail, Zephyr, or similar).
- Understanding of release management practices: versioning strategies, branching models, release trains, feature toggles, and rollback planning.
- Scripting and automation proficiency (e. g., Java Script/Type Script, Python, or Bash) to support test development and pipeline scripting.
- Strong analytical troubleshooting skills, meticulous attention to detail, and a demonstrated ability to bridge development, QA, and operations teams.
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.

- Salary
