Android Engineer
Poland | Remote | B2B
We’re a fast-growing AI wellness startup developing a personal training platform that makes fitness more intelligent, personalized, and engaging.

We adapt workouts in real time using movement data, body analysis, and recovery signals. Android is our fastest-growing platform — especially in MENA and LATAM, where we're scaling across a huge range of devices and hardware capabilities.
We're looking for an Android Engineer to own that experience end-to-end.

Responsibilities
  • Real-time workout flows – live exercise player, interactions and corrections during exercise
  • Camera for on-device CV + sensor fusion for body scan & fitness analysis
  • Build features both for core app and B2B SDK used within partners' ecosystems
  • Device fragmentation at scale, making all of the above work reliably on a budget Xiaomi in Cairo, not just a Pixel in a test lab
  • Translate design mockups and wireframes into high-quality system

We expect that you have
  • Production Android experience — apps with lots of real users, real crash reports, real performance issues
  • Use Jetpack Compose, Kotlin, Coroutines as daily tools; comfortable with DI frameworks (Dagger2/Hilt), modular architecture patterns (MVVM/MVI), GitFlow workflow
  • Strong understanding of asynchronous code on Android — concurrency, cancellation, async updates, partial data, and retry logic
  • Experience working with local persistence using Room
  • Understanding of background work on Android — background services, platform limitations, wake locks, and health data integrations
  • Performance improvements on real devices — profiling, memory, battery, thermal constraints
  • Experience with at least one of: camera APIs, sensor data, real-time processing on mobile
  • Ability to own a feature from problem definition through production monitoring
  • Comfort with complex backend integration — async updates, partial data, retry logic
  • Advanced LLM-assisted development flows
  • On-device ML or CV experience (TFLite, MediaPipe, CameraX pipelines)
