• Experience working in an existing production Android codebase.
• Comfortable owning your work independently, and available to start immediately.

Responsibilities

• Design and build a modular, reusable Android SDK in Kotlin that host apps can embed.
• Define the SDK interfaces and reusable native UI components host apps integrate against.
• Integrate REST APIs behind nutrition, meal-planning and AI-powered features, handling networking, error states and performance.
• Build secure authentication: token management, session handling, secure storage and user sync.
• Package, version and distribute the SDK with Gradle and AAR.

Job description

You'll build a reusable native Android SDK in Kotlin for an established Australian business developing nutrition and meal-planning technology. Third-party Android apps will embed what you build, so the work is as much about clean interfaces, packaging and documentation as it is about code.

It's a short, focused contract with a clear finish line: design the SDK, package and version it, prove it inside an existing production Android app, and support it through to release.
