Android Developer Needed for High-Performance Mobile Applications

We're hiring a passionate Android Developer to design, build, and maintain robust and efficient mobile applications for the Android ecosystem.

The ideal candidate will have hands-on experience with Kotlin, Java, and Android Jetpack, along with a strong understanding of UI/UX principles, API integration, and Firebase services.

You'll collaborate with cross-functional teams to deliver seamless, secure, and scalable apps that users love to interact with.

Key Responsibilities:

• Develop native Android applications using Kotlin and Java

• Implement MVVM / MVP architecture for scalability

• Integrate RESTful APIs and handle JSON data

• Use Firebase for authentication, database, and push notifications

• Design smooth, responsive, and modern UIs with Material Design

• Optimize performance and battery consumption

• Debug, test, and fix issues to ensure app stability

• Work with third-party SDKs and libraries

• Manage app release process on Google Play Store

• Write clean, well-documented, and maintainable code

• Collaborate with UI/UX and backend developers

• Conduct code reviews and ensure adherence to best practices

Required Skills:

• 3+ years of professional Android development experience

• Proficiency in Kotlin and Java

• Deep understanding of Android SDK and Jetpack libraries

• Familiar with Android Studio and Gradle build system

• Experience integrating Firebase (Auth, Firestore, Storage, Analytics)

• RESTful API integration and Retrofit / OkHttp / Volley

• Knowledge of Room Database / SQLite

• Familiar with LiveData, ViewModel, Coroutines, and Flow

• Experience with Material Design components

• Git version control and branching workflow

• Debugging using ADB, Logcat, and Profiler

• Unit testing and UI testing frameworks (JUnit, Espresso)

Android Architecture Patterns:

1. MVVM (Model-View-ViewModel):

   • ViewModel manages UI data

   • LiveData for reactive updates

   • Repository pattern for data abstraction

2. MVP (Model-View-Presenter):

   • Clear separation of UI and logic

   • Easier testing and code maintenance

3. Clean Architecture:

   • Domain, Data, and Presentation layers

   • Dependency Injection (Dagger/Hilt)

Firebase Integration:

• Firebase Authentication (Email, Google, Phone)

• Firestore Database for real-time data

• Firebase Storage for file uploads

• Firebase Cloud Messaging (Push Notifications)

• Firebase Crashlytics and Analytics

• Firebase Remote Config for dynamic updates

Core Android Concepts:

UI Components:

• RecyclerView, CardView, ConstraintLayout

• Navigation Component for fragment transitions

• ViewBinding / DataBinding

• Custom views and animations

Networking:

• RESTful APIs using Retrofit

• WebSocket or MQTT for live updates

• Secure data transmission (HTTPS, SSL pinning)

Performance Optimization:

• Memory management with LeakCanary

• Image loading using Glide or Coil

• Offline caching and pagination

• App startup optimization (App Startup Library)

Testing:

• Unit testing with JUnit

• Instrumented testing with Espresso

• Mocking dependencies with Mockito

Best Practices:

• Follow SOLID and Clean Code principles

• Use Android Jetpack libraries for modern development

• Follow Google's Material Design Guidelines

• Ensure backward compatibility (Android 8.0+)

• Maintain accessibility (content descriptions, TalkBack support)

• Implement secure storage (EncryptedSharedPreferences)

• Use dependency injection (Hilt / Dagger)

• Optimize network calls with WorkManager / Coroutines

Tools & Technologies:

• IDE: Android Studio

• Languages: Kotlin, Java

• Architecture: MVVM, Clean Architecture

• Libraries: Retrofit, Glide, Hilt, Room, Coroutines

Performance Metrics & KPIs:

• App launch time < 2 seconds

• Crash-free rate > 99.5%

• Battery usage optimization

• App size reduction and bundle optimization

• 90%+ score on Android Vitals (ANR, stability)

• Play Store rating 4.5+

Deliverables:

• Fully functional Android app (APK + source code)

• Firebase integration (Auth, Database, Notifications)

• API integration with backend services

• Documentation and comments

• Unit & UI test reports

• Deployment-ready build for Play Store

• 1–2 rounds of revisions and testing

Compliance & Standards:
