We are looking for a Senior Fullstack QA Engineer who combines a product mindset with a strong automation expertise - someone who understands the business and can analyze requirements, write test documentation, perform manual and automated testing and help others do the same.

You’ll work on:

• Intake Flow — smart document & data collection (questionnaires, checklists, automation)

• Take part in all team meetings (daily standups, sprint planning, refinement, and retrospectives) to advocate for quality early in the process
• Analyze requirements before development - participate in Three Amigos sessions, clarify requirements, and help define acceptance criteria and test scenarios that cover all business acceptance criteria
• Perform manual testing, design test cases, document bugs, and decide what should be automated and at what level (Unit vs. API vs. UI)
• Analyze logs and monitoring data (AWS, S3, application logs) to diagnose issues and validate system behavior
• Design and maintain automated tests (API/UI/E2E) based on real business scenarios
• Integrate suites into CI/CD (GitLab), track flaky tests and automation debt
