Job description

Job Description
Requirements

• Experience : 4+years

• Hands-on mobile engineering experience in iOS development.

• Hands-on experience developing and shipping production applications using React Native, JavaScript, and TypeScript.

• Hands-on native iOS development experience using Swift, SwiftUI, and UIKit, with working knowledge of Objective-C for legacy modules.

• Proven experience working on brownfield applications where React Native screens coexist with native iOS screens.

• Mandatory experience developing native iOS modules or view managers consumed by JavaScript through the legacy bridge and/or TurboModules and Fabric.

• Experience supporting high-traffic consumer applications in production, including crash investigation, bug fixing, hotfixes, and release management.

• Experience in e-commerce or content and commerce applications is preferred.

• Strong proficiency in JavaScript, TypeScript, React, and React Native component, navigation, and state-management architecture.

• Hands-on experience with state-management libraries such as Redux, MobX, Zustand, or Recoil.

• Strong understanding of React Native internals, including Hermes, Fabric, TurboModules, JSI, code generation, and the legacy bridge.

• Expertise in integrating React Native into large-scale native iOS applications, including hosting React Native views, developing native modules, bridging, and exposing native UI components.

• Strong Swift programming fundamentals, SwiftUI, UIKit, and working knowledge of Objective-C.

• Good understanding of iOS platform concepts, including application lifecycle, concurrency (GCD and async/await), memory management, networking, persistence, push notifications, deep links, universal links, App Store requirements, and privacy standards.

• Experience with mobile architecture patterns such as MVVM, Clean Architecture, object-oriented analysis and design, and modular application development.

• Strong knowledge of testing frameworks and practices across both platforms, including Jest, React Native Testing Library, Detox, and XCTest.

• Hands-on experience with Xcode, CocoaPods, Swift Package Manager, Metro, Fastlane, and CI/CD pipelines.

• Experience in production debugging, crash analysis, and performance profiling using Instruments, Hermes Profiler, Flipper, React DevTools, Crashlytics, or Sentry.

• Understanding of API integration, mobile security, caching strategies, and offline-first application development.

• Strong understanding of clean code principles, SOLID principles, and Agile development methodologies.

• Proven ability to manage end-to-end ownership of product modules, including architecture, implementation, testing, release, and production support.

• Experience in large-scale application migration, platform modernization, or refactoring initiatives with controlled rollouts and rollback strategies.

• Strong technical leadership, problem-solving, communication, and collaboration skills.

• Ability to conduct code reviews, mentor developers, establish engineering standards, and influence mobile architecture decisions.

• Experience with React Native migration from the legacy bridge to the new architecture (Fabric and TurboModules) is an added advantage.

• Familiarity with over-the-air updates using CodePush or EAS Updates, feature flags, and A/B testing platforms is desirable.

• Experience with monorepos, shared design systems, and e-commerce features such as catalogue, cart, checkout, and payments is an added advantage.
Responsibilities

• Architect, design, and develop customer-facing mobile features for the AJIO iOS application, with React Native as the primary development framework.

• Build scalable, reusable, and high-performance React Native components and modules using JavaScript and TypeScript.

• Develop and maintain native iOS features using Swift, SwiftUI, and UIKit wherever platform-specific capabilities, performance, or SDK integrations require native implementation.

• Maintain and enhance existing native iOS modules, including legacy components developed using Objective-C.

• Own end-to-end development of product modules, from requirement analysis and architecture design through development, testing, release, and post-production support.

• Own the integration layer between native iOS and React Native, including native modules, native UI components, bridging, and communication between JavaScript and native code.

• Ensure seamless user experience across native and React Native screens, covering navigation, back-stack management, session authentication, cart state, deep linking, analytics, and crash attribution.

• Drive the incremental migration of the existing native iOS application towards a React Native-first architecture without compromising application stability, performance, or release velocity.

• Define migration strategies, screen sequencing, feature parity, acceptance criteria, phased rollouts, feature flags, and rollback mechanisms.

• Support the live
