We are looking for a highly skilled Kotlin Developer to build a modern, scalable, and performance optimized Android application using the latest Jetpack libraries, Material Design standards, and clean architecture principles. The ideal candidate understands how to translate feature requirements into well structured screens, responsive layouts, stable data flows, and smooth user interactions.
You will be responsible for building the entire Android application from the ground up. This includes UI development with XML or Jetpack Compose, MVVM architecture, REST API integration, local database management, offline handling, push notifications, and performance tuning. Strong knowledge of Kotlin coroutines and modern asynchronous programming patterns is essential.
The project involves tight collaboration with backend teams, designers, and product management. We expect accurate execution of Figma UI designs, consistency in code style, and proactive communication when discussing features or problem areas. Real world Android experience such as managing configuration changes, optimizing layouts, handling memory usage, and preventing crashes is extremely important.
If you enjoy building Android apps that feel smooth, responsive, and production ready, and you have strong Kotlin expertise backed by real deliverables, this project will be an excellent fit.
