In this role, you will design, build, maintain, and continuously improve the automated test frameworks and quality-engineering practices that underpin high-volume, citizen-facing digital services handling billions of interactions annually. You will own the full testing lifecycle from strategic planning through to continuous integration and continuous deployment (CI/CD) pipeline integration. Working alongside software engineers, architects, and product owners, you will ensure that quality is built-in from the start, rather than bolted on at the end. You will be expected to code in the languages used across our modern tech stack and maintain a strong grasp of API, performance, security, and accessibility testing., * Framework Development: Design, build, and maintain automated test frameworks covering functional, regression, API, integration, performance, and security testing. * Pipeline Integration: Embed automated tests within CI/CD pipelines (e.g., Jenkins or GitHub Actions) to ensure continuous quality feedback and facilitate fast build cycles. * Strategy & Planning: Define and own the test strategy for assigned digital products, ensuring appropriate test coverage across unit, integration, system, performance, and accessibility layers. * Specialised Testing: Lead API testing for REST/GraphQL services using tools like RestAssured, Postman, or Karate, and execute performance/load testing using Gatling, k6, or JMeter to validate services at a massive national scale. * Accessibility & Security: Conduct rigorous accessibility testing aligned to WCAG 2.2 standards using automated tools (such as axe-core or Pa11y) and manual screen-reader testing, while embedding security testing practices (e.g., OWASP Top 10, DAST with OWASP ZAP or Burp Suite) within the delivery pipeline in support of secure-by-design principles. * Shift-Left Quality: Collaborate closely with software engineers, architects, and business analysts to define clear acceptance criteria, review code for testability, and champion shift-left quality practices. * Environment & Defect Management: Maintain test environments and test data strategies, manage the defect lifecycle, and produce clear quality dashboards and reports for the team and portfolio management. * Government Service Standards: Support formal government service assessments by providing concrete evidence of test coverage, quality metrics, and accessibility compliance. ## Related Videos - [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) - [Accessibility Test Driven Development](https://www.wearedevelopers.com/videos/1578-accessibility-test-driven-development) - [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) - [Collaboration Quantified: Lessons from Open Source Developer Networks](https://www.wearedevelopers.com/videos/1422-collaboration-quantified-lessons-from-open-source-developer-networks) - [Continuous Accessibility](https://www.wearedevelopers.com/videos/100170-continuous-accessibility) ## Related Articles - [The 8 Best Code Testing Tools](https://www.wearedevelopers.com/magazine/402-the-8-best-code-testing-tools) - [Dev Digest 120 - Apple and peers](https://www.wearedevelopers.com/magazine/455-dev-digest-120-apple-and-peers) - [Dev Digest 119 - ❤️ === ❤️](https://www.wearedevelopers.com/magazine/454-dev-digest-119) - [Dev Digest 133 - Back to Front](https://www.wearedevelopers.com/magazine/474-dev-digest-133-back-to-front) - [Why Upskilling And Reskilling is Important For Developers](https://www.wearedevelopers.com/magazine/428-why-upskilling-and-reskilling-is-important-for-developers) - [Dev Digest 121 - AI goes offline](https://www.wearedevelopers.com/magazine/456-dev-digest-121-ai-goes-offline)
