📋 Description

• Build and maintain the KMP shared core: business logic, state machines, and data models used by both the Android and iOS clients • Design the shared module's public API - decide what it exposes to platform-specific code and what stays internal • Keep the shared module platform-clean: no Android-only imports, plain data classes and suspend functions at the platform boundary • Wire up dependency injection using Metro (a newer DI tool similar to Dagger/Anvil) • Package the iOS side as an XCFramework and handle Kotlin/Native interop correctly for Swift consumers • Build and maintain a Jetpack Compose benchmark app on Android used to validate the shared core • Work with the Android and iOS engineers to migrate their existing native code onto the shared core

🎯 Requirements

• Production experience with Kotlin Multiplatform: shared module design, expect/actual, judgment on where platform boundaries belong • Experience building and shipping an SDK or library consumed by other developers - deciding what belongs in a public API and what stays closed • Dependency injection experience (Dagger, Anvil, Hilt, Koin, or similar); able to pick up Metro quickly • Working knowledge of Swift and iOS development, including how Kotlin/Native interop and Objective-C/Swift bridging work • Jetpack Compose experience • Strong Kotlin fundamentals: coroutines, suspend functions, structured concurrency • Compose Multiplatform experience - not needed now, but a likely future direction • Familiarity with Kotlin/Native specifics: memory model, concurrency constraints, interop edge cases • Android or iOS production experience beyond KMP itself • On-device AI / ML experience
