Your Mission & Who We Are Looking For:

• QA with 3 years+ hands on automation experience, alongside a strong manual testing foundation. You design and execute structured and exploratory test cases, validate complex user journeys across frontend and backend, and perform regression testing before releases. You identify edge cases and risk areas early and document clear, reproducible bug reports in Jira.
• You contribute to UI and API test automation using tools like Playwright, Cypress, or Postman, identify critical regression flows worth automating, and maintain existing test suites. CI/CD integration experience is a plus.
• API and data testing is part of your toolkit. You test APIs and data-driven dashboard features, and have basic SQL knowledge for backend data validation. You understand what correct looks like at the data layer, not just the UI.
• Quality ownership from day one. You participate in refinement and sprint planning from a QA perspective, help define acceptance criteria and test strategies, and proactively flag quality risks before they reach release.
• Plus: Experience in SaaS, AdTech, or performance marketing environments.

🌎 We welcome applications from talent worldwide and provide relocation support to Hamburg, Germany for those ready to join our team.
