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
