We’re looking for a skilled Android Developer who can design, develop, and optimize a modern mobile application built with Kotlin, Jetpack components, and Firebase.
This role focuses on building a feature-rich, fast, and secure Android application, supporting real-time updates, clean UI, API integration, background tasks, and payment systems.
You’ll collaborate closely with UI/UX designers, backend developers (Laravel/Node.js), QA testers, and product managers to ensure the app delivers an exceptional user experience across all Android devices.
Our ideal candidate understands architecture, performance, Material Design, and lifecycle management — not just coding screens. This is a project where your attention to detail, problem-solving, and ownership will make a massive impact.
This is a 2–3 month project with the potential to continue long-term for app expansion, optimization, and version updates.
Key Responsibilities
Develop high-performance apps using Kotlin and Android Jetpack.
Integrate REST APIs and handle secure data transmission.
Implement Firebase Authentication, Firestore, Notifications, and Analytics.
Build clean, responsive UI using Material Design 3 guidelines.
Implement MVVM architecture and follow clean code practices.
Set up local storage using Room Database or SQLite.
Handle payments (Google Pay, Razorpay, Stripe SDK).
Optimize app performance (load time, responsiveness, memory).
Manage background services, WorkManager, and lifecycle events.
Identify and fix bugs using profiling tools.
Implement push notifications and in-app alerts.
Ensure compatibility across multiple devices and screen sizes.
Collaborate with designers to achieve pixel-perfect UI.
Prepare signed builds (AAB/APK) and publish on Play Store.
Document workflows, APIs, architecture, and release notes.
Required Skills
3+ years of experience in Android development.
Strong Kotlin experience (preferred) or Java expertise.
Jetpack Components: ViewModel, LiveData, Navigation, Room, Paging.
REST API integration using Retrofit, OkHttp, or Ktor.
Firebase modules: Auth, Firestore, Cloud Messaging, Analytics.
MVVM or Clean Architecture design patterns.
Knowledge of dependency injection (Hilt/Dagger).
Familiarity with Git and proper version control workflows.
Strong debugging skills with Logcat and Android Profiler.
Experience with Play Store deployment & release management.
Understanding of app security best practices (SSL pinning, encryption).
Basic knowledge of UI testing (Espresso) and unit testing (JUnit).
Knowledge of performance optimization and caching strategies.
Comfort working with Figma or XD design handoffs.
Clear communication and ability to work independently.
