• 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

Qualifications

• 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
• All candidates must be based in Brazil
