Job Description:

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, NativeFlutter Interoperability, and complex SDK integration.

Key Responsibilities

• 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.
• 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.
