Job summary

Millbrook Healthcare Group is seeking a quality-focused tester to join the product engineering team. You will drive testing early in development, refine acceptance criteria, and balance manual testing with automation to speed feedback.

The role emphasizes Playwright automation, API and integration testing, and improving CI/CD quality gates. You will test modern (.NET/React) and legacy systems across SQL-driven workflows, contributing to a robust quality culture.

Qualifications

• Commercial software testing experience across the full SDLC.
• Strong exploratory, functional, integration and regression testing skills.
• Experience with test automation; Playwright preferred.
• API testing experience and SQL data validation.
• Understanding of CI/CD and delivery pipelines.
• Analytical thinking, attention to detail and communication.
• Comfortable challenging unclear requirements.

Responsibilities

• Review user stories, acceptance criteria and designs before development starts and identify gaps, edge cases and quality risks.
• Create proportionate test approaches covering functional, integration, regression, exploratory and non-functional testing.
• Prepare and manage test data reflecting realistic business behaviour.
• Raise clear, reproducible defects with enough evidence for engineers to diagnose quickly.
• Test throughout the SDLC rather than as a final gate before release.
• Use risk to decide where deeper testing is needed.
• Build and maintain automated tests for web apps, APIs and critical user journeys.
• Integrate automated tests into Azure DevOps CI/CD pipelines and help define meaningful quality gates.
• Keep automated tests reliable and maintainable; remove or improve tests that create noise.
• Work with engineers to improve application testability and move checks earlier in the lifecycle.
• Establish sensible automation patterns reusable across products.
• Test REST APIs, integrations and service behaviour using appropriate tools.
• Use SQL Server and T-SQL to validate application behaviour, test data and downstream outcomes.
• Carry out or support load, performance, resilience and compatibility testing where risk warrants it.
• Include accessibility, security and supportability considerations in test thinking.
• Validate integrations across APIs, files, queues/messages and database boundaries.
• Work closely with Product and Engineering during refinement, development and release.
• Help improve Definition of Ready, Definition of Done and acceptance-criteria quality.
• Give the team a clear view of release risk beyond pass/fail answers.
• Share testing knowledge and help engineers take more ownership of quality.
• Use escaped defects and production incidents to improve automated coverage.
