Android/iOS App Developer (Kotlin Multiplatform, KMP) (m/f/d)

Remote in Germany Full-time or part-time Mid to senior

You are an experienced Android developer who builds shared logic with Kotlin Multiplatform (KMP) and understands iOS well enough to keep shared code working cleanly on both platforms. You will build companion apps for connected devices, Android first, with KMP modules shared across Android and iOS.

What you'll do

  • Build and ship companion apps for connected devices in Kotlin, Android first
  • Design shared KMP modules for business logic, data, and device communication
  • Integrate BLE devices, cloud backends, and synchronization flows
  • Keep shared code running cleanly on iOS, together with us
  • Contribute to architecture decisions early, while they are still cheap to change

What you bring

  • Professional Android development experience with Kotlin
  • Hands-on KMP experience with shared modules you have built and maintained
  • A working understanding of iOS foundations: Swift, Xcode, app lifecycle
  • A completed academic degree, or equivalent professional experience
  • English and German at B2 level or better
  • Residence in Germany
