Integrate RESTful APIs and handle asynchronous data flows
Collaborate with backend engineers to define and evolve API contracts
Ensure app performance, responsiveness, and stability across a range of devices
Identify bottlenecks and bugs, and implement fixes with minimal supervision
Contribute to code reviews, technical discussions, and architectural decisions
Continuously improve code quality, tooling, and development processes

Requirements

Strong experience building Android applications in Kotlin
Solid understanding of Android SDK, app lifecycle, and common pitfalls
Experience with modern Android development tools and libraries (e.g., Jetpack components, Coroutines, Flow)
Familiarity with dependency injection (e.g., Hilt, Dagger)
Experience consuming and designing REST APIs
Good understanding of threading, memory management, and performance optimization on Android
Experience writing unit and instrumentation tests
Comfortable working with Git in a collaborative environment
English level: Fluent
