• Design, build, and ship Android features in a large production app;
• Contribute to Android infrastructure so delivery stays fast and reliable.
• Review code, give feedback to other developers, and write technical documentation to improve coding practices and code quality.
• Lead development initiatives, whether by introducing new technologies or by raising the bar for existing code, practices, or architecture.
• Take part in decisions with peers and stakeholders on technology, design, and product direction.
• Triage product and application issues, and respond quickly to customer problems.

• Proficiency in Kotlin and building user interfaces with Jetpack Compose.
• Solid understanding of the Android SDK:

• Performance tuning and optimization.
• Gradle builds and modules.
• Strong understanding of concurrency practices and experience working with coroutines;
• Must be capable of making architectural judgment calls based on real data and requirements.
• Working knowledge of MVVM and standard multi-tier architecture.

Nice to Have

• Experience with CI/CD, automated testing, and publishing to the Play Store.
• Solid foundation in data structures and algorithms, with a focus on delivering testable, scalable, and maintainable code.
• Experience using AI / LLM tools in day-to-day development, including how to keep quality, review standards, and security intact when you use them.
• Experience with modern Android frameworks such as Dagger/Hilt and OkHttp/Retrofit,
• Experience building automated test suites with Espresso/kakao and a clear view of what belongs in unit, integration, and UI tests.
• Familiarity with:
• Accessibility best practices for mobile applications.
• OAuth, mobile app authentication, and data safety.
• Material Design principles, mobile UX practices, and patterns
