Senior Android developer

We are currently looking for a Senior Android developer to work on the Frisbee project — a secure and fault-tolerant corporate messenger for effective teamwork. Frisbee combines the ease of use of public messengers with the features needed for work, and offers various solutions for secure storage and deployment.

Our Android application is written in Kotlin. We follow the principles of Clean Architecture and use the MVVM pattern. We actively use a reactive approach, have transitioned to Coroutines and Flow, although there's still a bit of RxJava left. Interaction with the server occurs via REST and SSE (socket). For network requests, we use Retrofit 2 and OkHttp. The database is Room, navigation is implemented with Cicerone, and for dependency injection, we use Toothpick. Development is done in Android Studio using the Git version control system, and tasks are tracked in Jira.
