Role: Flutter Engineer Android Native Integration

Experience : 4-8 years

Location: Bangalore

Notice Period: Immediate Joiner

Role Overview:

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 NativeFlutter 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 / Valuable 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.
