• Contribute to test automation strategy, framework improvements, and engineering best practices for test code
• Perform functional, regression, integration, and exploratory testing where needed
• Validate complex business workflows related to trading, order lifecycle, and data processing
• Collaborate with developers during feature design and implementation to identify testability gaps and quality risks
• Participate in requirements analysis, test scenario design, and technical review discussions
• Analyze application logs, service behavior, data flows, and, when needed, source code to investigate test failures and defects
• Identify, document, and track defects through their lifecycle
• Enhance and maintain test documentation and automated test coverage
