Join the ride!

You assure quality across our consumer mobile app and our business web platform, from

test design to production monitoring. You build the automation, define what release-

ready means, and contribute to the final human sign-off before each release.

than ever. Your work lets every team ship quickly and with confidence.

Note: This role is Berlin based.

• Assist in release validation and the final human sign-off on every release
• Set up production monitoring and follow findings through to a fix
• Effectively deploy and use AI agents

Your Experience

• 5+ years in QA automation, site reliability or a closely related engineering role
• Proficiency in TypeScript or JavaScript and Python, and a firm grasp of backend, frontend and database concepts
• Mobile end-to-end automation with Appium, Detox or Maestro on iOS and Android
• Web end-to-end automation with Playwright; Selenium or Cypress also welcome
• API, performance and security testing, including OWASP basics, with tools such as Postman and k6
• CI pipeline authoring, such as GitLab CI or GitHub Actions, and SQL for data validation
• Clear bug reports and acceptance criteria that others can act on
• A valid driving licence (EU category B or equivalent); testing the product includes trips on the road.

Highly desired

• Experience in mobility, logistics or another operations-heavy consumer product
• Testing payment flows in a consumer or business product
• Monitoring and observability tooling for production systems
• Writing test code in Go or another typed backend language
• GDPR-aware test data handling
• Accessibility and usability testing

Don't tick every box? Get in touch anyway. Your drive to learn and grow matters a lot to us.

Benefits

• Discounts: Access 1,500+ providers for discounts on sneakers, theater visits, and more.
