Responsabilidades

• Manual testing across active releases (feature acceptance, smoke, regression, integration).
• Test API flows and validate integrations between services.
• Create, maintain, and optimize test cases and regression suites in QASE / TestRail / Zephyr.
• Automate test cases as they stabilize (Python / Playwright) and grow automated regression suites.
• Maintain and extend existing automated tests, keeping them aligned with product changes.
