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. • 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: • 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.
