Desirable

• As a QA Automation Engineer, you will work within a multidisciplinary team to build quality into complex digital services
• This is a hands-on engineering role focused on designing, developing and maintaining automated tests using Java. You will test APIs, user journeys and integrations across distributed services, providing reliable feedback throughout development and clear evidence to support release decisions
• You will work closely with developers, DevOps engineers, business analysts, product owners and operational teams to understand requirements, identify risks and verify that business processes complete correctly. You will take ownership of automation quality, investigate failures and continually improve the reliability, coverage and maintainability of the test suites
• Design, develop and maintain automated API, integration and end-to-end tests using Java, Serenity BDD, Cucumber, Selenium WebDriver and REST Assured
• Contribute to reusable test components and maintainable automation frameworks, applying sound coding practices and participating in code reviews
• Work with developers, business analysts and product owners to define testable acceptance criteria and appropriate positive, negative and boundary scenarios
• Select the appropriate level of testing for each risk, balancing coverage, execution time and maintenance effort
• Integrate and maintain automated tests within Azure DevOps CI/CD pipelines, providing timely and actionable feedback
• Test asynchronous workflows and interactions between services, including event processing, messaging, retries and failure recovery
• Verify completed business outcomes through APIs, database checks and user journeys, including downstream processing and data consistency
• Create and maintain repeatable test data, accounting for environment dependencies, test isolation and parallel execution
• Investigate failures using application logs, API responses, database queries and pipeline results, distinguishing application defects from automation, data and environment issues
• Improve suite reliability by addressing flaky tests, unnecessary duplication and gaps in regression coverage
• Turn production defects and recurring incidents into repeatable automated regression scenarios
• Perform targeted exploratory testing and contribute to performance, accessibility, security and operational readiness testing alongside relevant specialists
• Maintain test coverage, execution records and release evidence in Jira/Zephyr, ensuring results are traceable to the relevant change, environment and release
• Raise clear, reproducible defects and work with the team to triage, resolve and verify them
• Communicate testing progress, outcomes, residual risks and coverage limitations clearly to technical and non-technical stakeholders
