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 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
- 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.
- Solid 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:

- Base location: Bengaluru
- 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.
