The Role

You'll join a small, focused team building a best-in-class companion app for the next generation of athletes. This starts as a 6-month freelance engagement with the clear intention of moving into a full-time position.

What we're looking for

Senior-level Android experience — you've shipped production apps and can own decisions end to end.

Kotlin Multiplatform (KMP) — you've worked cross-platform (iOS + Android) and know where shared code helps and where it doesn't.

Jetpack Compose — comfortable building modern declarative UIs at scale.

Consumer app background — experience with video, animations, and the kind of polish that users actually notice.

AI-integrated workflow — you've used AI tools in your day-to-day and can bring that mindset to the team.

Please be precise in your application about:
  • Your experience with KMP
  • Your potential start date
