Software Quality Assurance Engineer (Manual)

As a Software Quality Assurance Engineer (Manual), you will take ownership of the functional quality of assigned features and releases. Your role will be to make sure that delivered functionality meets business requirements, acceptance criteria, and user expectations. 

You will work closely with Development and Product teams, turning requirements into structured test scenarios, identifying defects, validating fixes, and providing clear feedback throughout the development process. You will also help us make our QA practices more consistent, transparent, and effective as the company grows. 

This is a hands-on role for someone who is comfortable working independently, investigating how systems behave, asking questions when something is unclear, and taking responsibility for the quality of their work. You will work primarily with manual testing, while also having the opportunity to contribute to testing non-LLM machine learning models if you have the relevant experience 

What You Will Do 

• Own the functional quality of assigned features and releases. 
• Analyse business requirements and translate them into structured test cases and test scenarios. 
• Design, maintain, and execute manual tests using Azure Test Plans or similar tools. 
• Identify, document, and track defects in ClickUp, providing clear, reproducible bug reports. 
• Validate REST APIs using tools such as Postman or Bruno, including requests, responses, HTTP methods, and status codes. 
• Validate data integrity and end-to-end data flows using PostgreSQL/SQL queries. 
• Use browser DevTools to investigate issues and support troubleshooting. 
• Verify fixes and perform regression testing to ensure changes do not introduce new issues. 
• Maintain test plans, test cases, and other QA documentation. 
• Work closely with Product and Development teams to clarify requirements, communicate risks, and improve product quality. 
• Contribute to the continuous improvement of QA processes, testing practices, and team ways of working. 
• Where applicable, support QA activities related to non-LLM machine learning models, including local inference runs, data validation, output consistency, and awareness of model drift.
