Role Overview:

We are looking for a skilled Flutter Engineer with strong 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:


• MethodChannel


• EventChannel


• BasicMessageChannel


• 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.


• 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:

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


• This profile involves occasional travelling to client locations.


• Hybrid is our default way of working. Each domain has customized the hybrid approach to their unique needs.
