Key Responsibilities

• Design, develop, and maintain scalable automated test suites for database-driven applications, APIs, and web interfaces.
• Take ownership of test automation activities throughout the software development lifecycle, from requirements analysis to production release.

• Analyse requirements and technical designs to identify risks, ambiguities, dependencies, and testability concerns early in the delivery process.
• Investigate complex failures across application, API, database, and infrastructure layers, clearly communicating findings and supporting root-cause analysis.
• Integrate automated tests with version control and continuous integration workflows.
• Review test code and contribute to coding standards, reusable components, and maintainable automation practices.
• Track and communicate quality risks, test coverage, defects, and release-readiness information to technical and non-technical stakeholders.
• Use AI-assisted tools responsibly to improve activities such as test design, test-data creation, code generation, failure analysis, and technical documentation, while reviewing generated outputs for accuracy and compliance.
• Collaborate proactively with colleagues across different functions, locations, and cultures.
• Contribute to continuous improvement initiatives across quality assurance and software engineering practices.
• Share knowledge and provide technical guidance through peer reviews, documentation, and day-to-day collaboration, without formal people-management responsibilities.
