• Reviewing requirements, specifications, and API documentation to identify risks and test considerations.
• Performing manual and exploratory testing across API and, where relevant, UI layers.
• Clearly recording defects so they can be reproduced and resolved efficiently.
• Creating and maintaining test documentation, logs, and test evidence.
• Helping identify opportunities to improve product and API quality and reliability.
• Assisting with troubleshooting issues across services and components.
• Automation and quality growth
• Working with existing automated API tests, including executing tests and reviewing test results.
• Contributing to the expansion of automated API test coverage under guidance from senior QA and engineering.
• Supporting the identification of gaps in test coverage and opportunities to improve reliability through automation.
• Developing skills in automation and modern testing practices as part of the role.

Required qualifications

• Experience designing and executing test scenarios and test cases.
• Experience with bug tracking tools and clear, reproducible defect reporting.
• Ability to apply exploratory testing techniques and critical thinking.
• Experience prioritising issues based on user impact and product context.
• Understanding of quality attributes such as correctness, reliability, and consistency.
• Experience working in agile or lean development environments.
• Fluent written and spoken English.
• Strong communication skills, attention to detail, and analytical thinking.
• A proactive mindset and genuine interest in improving product quality.

Additional desirable API experience
