• Perform exploratory and manual testing where it delivers the greatest value
• Provide clear, risk-based recommendations to support release decisions
• Contribute to security focused testing, including OWASP principles and lightweight threat modelling
• Help ensure products meet accessibility standards by testing against WCAG guidelines
• Continuously identify opportunities to improve testing processes, tooling, and overall product quality

What We're Looking For

• 5+ years' experience in software testing or quality engineering
• Strong experience with test automation across UI, API, and integration testing
