Company Description 👋🏼We're Nagarro. We are a Digital Product Engineering company that is scaling in a big way! We build products, services, and experiences that inspire, excite, and delight. We work at a scale — across all devices and digital mediums, and our people exist everywhere in the world (18500+ experts across 39 countries, to be exact). Our work culture is dynamic and non-hierarchical. We are looking for great new colleagues. That is where you come in! 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 production application by investigating and resolving issues across native and React Native layers, managing crash triage, hotfixes, and production releases. • Monitor and improve application performance, including cold start time, React Native time-to-interactive, bundle size, memory consumption, rendering performance, and frame drops. • Use Xcode Instruments, Hermes Profiler, Flipper, and React DevTools to identify and resolve performance bottlenecks. • Own the iOS build and release pipeline, including Xcode project configuration, CocoaPods, Swift Package Manager (SPM), Metro, Hermes, code generation, signing, Fastlane, CI/CD, and App Store phased releases. • Define and enforce engineering standards across native iOS and React Native development, including architecture patterns, coding practices, code reviews, and testing frameworks. • Develop reusable libraries, shared components, and design-system elements that work consistently across native and React Native interfaces. • Implement automated and unit testing strategies using Jest, React Native Testing Library, Detox, and XCTest. • Collaborate with product managers, UX/design teams, backend engineers, and QA teams to understand requirements and deliver high-quality mobile solutions. • Evaluate native iOS versus React Native implementation approaches and advise stakeholders on appropriate technical trade-offs. • Mentor junior and mid-level engineers, including supporting native iOS developers in adopting React Native development practices. • Drive architectural decisions, manage technical debt, maintain performance budgets, and continuously improve code quality throughout the migration journey. Qualifications Bachelor’s or master’s degree in computer science, Information Technology, or a related field.
