• Create and maintain appropriate test plans, test cases, checklists, and other QA documentation
• Identify, document, track, and communicate defects clearly
• Work closely with developers, product owners, and other stakeholders throughout the development lifecycle
• Participate in integration and E2E testing across multiple services and components
• Identify testing risks, gaps, dependencies, and potential quality issues early and communicate them proactively
• Support delivery planning by estimating testing effort and highlighting dependencies or blockers
• Contribute to improving QA processes, test coverage, and overall product quality

• Excellent attention to detail, with the ability to identify edge cases and inconsistencies
• Ability to understand complex system flows and dependencies between multiple services/components
