Android Native & Flutter Developer

We are looking for a skilled Flutter Engineer with strong hands-on Android Native

development experience to design, develop, integrate, and maintain high-quality mobile applications.

The ideal candidate should have deep expertise in Flutter/Dart as well as Android native development using Kotlin, with proven experience integrating Flutter applications with native Android components, SDKs, platform services, and third-party libraries.

The role requires strong engineering fundamentals, with particular emphasis on Clean

Architecture, Secure Coding, Application Security, Encryption, Performance, and

Native–Flutter Interoperability.

Key Responsibilities

Design and develop scalable mobile applications using Flutter and Dart.

Develop and maintain Android native components using Kotlin.

Build Robust Flutter-to-Native Integrations Using

• Platform Channels
• MethodChannel
• EventChannel
• BasicMessageChannel
• Native APIs where applicable
  
  

Integrate native Android SDKs and third-party SDKs into Flutter applications.

Develop Flutter plugins/wrappers for native Android capabilities when required.

Analyze and troubleshoot issues across the Flutter, Dart, Android, and native SDK

layers.

Design applications using Clean Architecture, SOLID principles, design patterns,

and modular architecture.

Implement secure coding practices across both Flutter and Android native layers.

Work On Application Security Areas Including

• Encryption/decryption
• Secure key management
• Android Keystore
• Secure storage
• Certificate/public-key pinning
• Secure network communication
• Data protection
• Root/jailbreak and tampering considerations
  
  

Integrate and maintain security, authentication, payment, analytics, monitoring, and

other enterprise SDKs.

Optimize application performance, memory usage, startup time, network usage, and

rendering performance.

Troubleshoot complex issues involving Flutter ↔ Android ↔ SDK ↔ Backend

interactions.

Implement unit, widget, integration, and native-layer tests.

Participate in code reviews and ensure adherence to coding and architectural

standards.

Collaborate with architects, backend engineers, QA, DevOps, security teams, and

product stakeholders.

Contribute to technical design, estimation, documentation, and engineering best

practices.

Preferred / Good To Have

Experience in Banking, FinTech, Payments, UPI, or other security-sensitive

applications.

Experience migrating or integrating existing native Android applications with Flutter.

Experience developing Flutter plugins.

Experience with Kotlin Coroutines and Flow.

Experience with Jetpack libraries.

Experience with Firebase/App Distribution/Crashlytics or equivalent.

Experience with performance profiling and memory-leak analysis.

Knowledge of mobile application threat modelling.

Experience working in Agile/Scrum environments.

Good understanding of Android Gradle build system.

Experience with build variants/flavors and environment configuration.

Familiarity with CI/CD pipelines for mobile applications.

Unit testing with appropriate Flutter/Dart and Android testing frameworks. Widget

and integration testing.

Strong understanding of code quality, static analysis, and code review practices.

What We Expect

The candidate should be an engineer who can work across both Flutter and Android Native layers, rather than a Flutter-only developer.

They should be able to independently investigate an issue that starts in Flutter, crosses a platform channel, enters Kotlin code, interacts with a third-party SDK, and identify and resolve the problem end-to-end.

Strong emphasis will be placed on hands-on technical capability, architecture, native

integration, security, debugging, and problem-solving skills.
