Job description As a Grade 7 Senior Test Engineer, you will join the Quality Engineering team within the GOV.UK One Login program. This role involves leading test engineering efforts for product and cross-product delivery, covering both functional and non-functional testing. A key part of this role is championing quality engineering initiatives to ensure the seamless integration and delivery of reliable and resilient products. You will also have the opportunity to drive innovation in testing methodologies, mentor team members, and embed quality engineering practices throughout our software development lifecycle.

As a Senior Test Engineer, you’ll

  • drive continuous improvement by leading and guiding teams in quality engineering, and optimising quality practices and processes
  • act as a subject matter expert in test engineering, continuously learning new functional and non-functional testing (performance, accessibility, resilience etc) technologies, and supporting teams with their adoption
  • lead and guide quality engineers in defining the test approach, test planning, and implementing automated test suites to ensure both functional and non-functional acceptance criteria are met
  • conduct Operational Acceptance Testing (OAT) to ensure systems meet all operational requirements and are production-ready
  • analyse technical, functional, and business requirements, gathering evidence to identify problems and opportunities, and ensure recommendations align with strategic business objectives
  • influence the architecture and design of new features early in the development cycle to drive quality, testability, and specification adherence

Person specification

We’re interested in people who

  • have proven ability to lead and manage all phases of testing (functional and non-functional) across multiple teams, from initial business understanding through to production delivery. This includes expertise in technical leadership, quality improvement, developing test strategies, automation, reporting, and testing in CI/CD environments
  • have demonstrated success in implementing automated testing solutions for Mobile, Web UI, and API, consistently driving quality improvements. Proficient in JavaScript or TypeScript for programming
  • have experience in leading non-functional testing, specifically Performance, Accessibility, Resilience testing and Compatibility testing. Proficient in applying a diverse range of test types, tools, and industry standards
  • are an adaptable team member within a Continuous Integration/Continuous Delivery (CI/CD) environment, demonstrating competency in the deployment of relevant tools and methodologies. Initiates proactive measures to implement and champion 'shift left and shift right' quality assurance principles
  • can cultivate a quality-centric, 'whole team' approach, and enhance the testing capabilities within delivery teams
  • have comprehensive understanding of production testing, observability, and real-usage monitoring. Able to implement risk-based test strategies that guarantee system reliability and provide actionable insights into user behaviour

Please note This role requires SC clearance, which would normally need 5 years’ UK residency in the past 5 years. This is not an absolute requirement, but supplementary checks may be needed where individuals have not lived in the UK for that period. This may mean your security clearance (and therefore your appointment) will take longer or, in some cases, not be possible. DSIT cannot offer Visa sponsorship to candidates through this campaign. DSIT holds a Visa sponsorship licence but this can only be used for certain roles and this campaign does not qualify.
