Key Responsibilities
Flutter Engineer – iOS Native & Flutter

Experience:
3 – 8 Years Role: Flutter Engineer – iOS Native Integration Role Overview: We are looking for a skilled Flutter Engineer with solid hands-on iOS Native development experience to design, develop, integrate, and maintain high-quality mobile applications. The ideal candidate should have strong expertise in Flutter/Dart as well as iOS native development using Swift, with proven experience integrating Flutter applications with native iOS 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, Native–Flutter Interoperability, and complex SDK integration.
• Design and develop scalable mobile applications using Flutter and Dart.
• Develop and maintain iOS native components using Swift.
• Build robust Flutter-to-iOS Native integrations using:
• Method Channel
• Event Channel
• Basic Message Channel
• Custom Flutter plugins
• Integrate native iOS SDKs and third-party frameworks into Flutter applications.
• Develop Flutter plugins/wrappers for native iOS capabilities where required.
• Analyze and troubleshoot issues across the Flutter, Dart, iOS, and native SDK layers.
• Design applications using Clean Architecture, SOLID principles, design patterns, and modular architecture.
• Implement secure coding practices across Flutter and iOS native layers.




• Integrate authentication, payment, security, analytics, monitoring, biometric, and other enterprise SDKs.
• Optimize application performance, memory usage, startup time, network usage, and UI responsiveness.
• Troubleshoot complex issues involving Flutter ↔ iOS ↔ 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 iOS applications with Flutter.
• Experience developing Flutter plugins.
• Strong Swift concurrency knowledge.
• Experience with UIKit and SwiftUI.
• Experience with Firebase/App Distribution/Crashlytics or equivalent.
• Experience with performance profiling and memory-leak analysis using Xcode Instruments.
• Knowledge of mobile application threat modelling.
• Experience with App Attest, DeviceCheck, Secure Enclave, and advanced iOS security mechanisms.




• Experience working in Agile/Scrum environments.
• Experience with CocoaPods and/or Swift Package Manager.
• Familiarity with CI/CD pipelines for Flutter and iOS applications.
• Experience troubleshooting dependency, signing, provisioning, and build issues.
• Understanding of Flutter iOS build and release processes.
• Experience managing different environments/flavors/configurations is desirable.
• Unit testing using XCTest and appropriate Flutter/Dart testing frameworks. Widget and integration testing. Mocking and dependency isolation.
• Experience debugging production issues using logs, crash reports, stack traces, and performance tools.
• Familiarity with Xcode Instruments for performance and memory analysis.
• 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 iOS 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 Swift/Objective-C, 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, iOS native expertise, Flutter integration, architecture, security, SDK integration, debugging, performance, and problem-solving skills. Location and way of working:
