The Opportunity:
We're looking for an Android Engineer to join our Software team and help design, build, and evolve the native Android apps that players and coaches rely on, on the training pitch, on match day, and everywhere in between. This is a product-focused role where you'll take ownership of features end-to-end, from Bluetooth communication with our wearable GPS devices and data sync through to polished, user-facing experiences in Kotlin and Jetpack Compose. You'll work closely with Product Owners, designers, and our iOS and backend engineers, and you'll have real scope to bring AI-powered features to life, both on-device and through our AWS generative AI stack. If you're enthusiastic, curious, love solving problems creatively, and follow the sport as closely as you follow the tech, this role is for you.
What You'll Be Doing:

- Building reliable Bluetooth Low Energy communication with our wearable devices, pairing, data transfer, and background sync using foreground services and WorkManager, across the wide range of Android devices our players use
- Building and integrating AI-powered features, consuming services built on AWS Bedrock, and exploring on-device capabilities such as ML Kit and Gemini Nano
- Integrating with our serverless backend APIs and designing for offline-first use, with solid caching and sync (e.g. Room) so the app works on the side of a pitch with patchy signal
- Owning and improving the
