• Automation Implementation: Design and implement an automation framework or suite to improve test efficiency, reduce manual workload, and provide quicker feedback loops for development teams.
• Mentoring: Lead and mentor another QA tester on the team, providing guidance on testing best practices, test script creation, and overall QA methodologies.
• Cross-Functional Collaboration: Collaborate with Product Managers, Developers, and other stakeholders to clarify requirements, raise issues early, and ensure smooth release cycles.
• Defect Management: Investigate, document, and track bugs in our issue management tools; work with engineering teams on bug prioritisation and resolution time-lines.
• Continuous Improvement: Help shape QA processes, refine testing tools, and advocate for quality throughout the development life cycle.
• Reporting & Metrics: Establish and monitor key quality metrics (e.g., defect density, test coverage) to provide insights into product stability and team effectiveness.

Skills and Experiences we are looking for:

• Brings senior-level testing expertise, with demonstrable experience leading QA efforts on complex software products.
• Excels at methodical problem-solving, able to create thorough and reproducible test plans.
• Has hands-on experience building out test automation frameworks from scratch, and selecting the appropriate tooling and technologies to do so.
• Is comfortable mentoring and guiding the professional growth of a junior QA colleague.
• Enjoys working on both legacy systems (requiring careful troubleshooting and exploratory testing) and new product lines (providing opportunities to implement modern QA practices).
• Thrives in a collaborative environment, maintaining open communication with engineers, product managers, and business stakeholders.
