- Collaborate with our QA team to ensure every release meets our quality standards.
- Contribute to our CI/CD pipelines (Fastlane & Jenkins), keeping delivery smooth and reliable.
- Occasionally dive into native Android/iOS code β especially for Bluetooth background connections or other platform-specific needs.

- Put your English communication skills to use in our agile team meetings (Scrum) β and maybe practice a little German over coffee with colleagues.
