Description
We’re looking for an Android engineer who is comfortable owning features end-to-end and making pragmatic technical decisions. This role is hands-on: you’ll be building and maintaining production-grade Android applications using Kotlin, working closely with product, design, and backend teams. The codebase is actively evolving, so expect to balance shipping features with improving architecture and code quality.

- Work with modern Android architecture patterns (MVVM, MVI, or similar)
- 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
- All candidates must be based in Brazil
Nice to have:
- Experience with Jetpack Compose in production
- Familiarity with modularized architectures
- Experience with CI/CD pipelines for Android
- Exposure to Kotlin Multiplatform
- Understanding of offline-first architectures and caching strategies
