• 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.

• 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

• 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.

• 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. 

• 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.

Desired Qualifications:

• Base location: Bengaluru
• Education: Professional Qualification - B.E./B.Tech/MCA/MBA/MS
