Or, alternatively, Master’s degree in Applied Computer Science, Computer Science, Engineering, Information Technology, Information Systems, or a closely related field (or foreign education equivalent) and three (3) years of experience as a Principal Mobile Developer (or closely related occupation) performing native Android application development in a software engineering domain.

Skills and Knowledge:

Candidate must also possess:

• Demonstrated Expertise (“DE”) developing native Android applications using Kotlin and Java; performing UI development with XML and Jetpack Compose; and implementing MVVM architecture for scalable and maintainable codebases, using Android Studio, Gradle, and Jetpack libraries (ViewModel, LiveData, and Navigation).
• DE integrating RESTful APIs and managing data persistence, using Room and Firebase Realtime Database; and integrating secure data handling, offline capabilities, and synchronization strategies, using Retrofit, Gson, and Firebase Authentication.
• DE implementing advanced Android UI/UX features, including RecyclerView, ConstraintLayout, Fragments, animations, and Material Design principles; and adapting layouts for multiple screen sizes and orientations, and optimizing performance for low-resource devices.
