Job Overview

Barclays is hiring a React Native and iOS Developer for its technology organization in Pune. This is a permanent full-time opportunity focused on building, improving, and maintaining secure, scalable, and high-performance mobile applications. The role combines cross-platform development with native iOS engineering and requires close collaboration with product owners, UX designers, backend engineers, QA teams, and other technology professionals.

The successful candidate will contribute across the mobile application lifecycle, from designing reusable interface components and integrating backend services to testing, troubleshooting, performance tuning, and supporting secure application delivery. The position is particularly suited to developers who are comfortable working with React Native while also understanding the iOS platform and native development ecosystem.

Key Responsibilities

• Develop and maintain cross-platform mobile applications using React Native with a strong focus on reliability, responsiveness, and usability.
• Build native iOS components and modules when application requirements need platform-specific functionality.
• Create reusable and scalable UI components that can support consistent mobile experiences.
• Connect mobile applications with REST APIs, JSON-based services, and third-party integrations.
• Implement appropriate state management using Redux, Redux Toolkit, Context API, Zustand, or similar approaches.
• Use React Hooks and React Navigation to structure modern mobile applications.
• Work with UX and UI teams to turn designs into accurate, responsive, and user-friendly mobile interfaces.
• Diagnose and resolve application defects across supported iOS devices and development environments.
• Improve application performance through profiling, optimization, and efficient implementation techniques.
• Participate in peer reviews and promote maintainable coding practices.
• Develop unit, integration, and UI tests to improve application quality and reliability.
• Work within Agile and Scrum delivery practices and collaborate with cross-functional teams.
• Support secure software development by following appropriate coding and application security practices.
• Contribute to continuous improvement and stay informed about mobile development technologies and industry trends.

Required Skills

Candidates should have practical experience with React Native and modern JavaScript or TypeScript development. Strong knowledge of React concepts, including Hooks, reusable components, navigation, and state management, is important for this position.

The role also requires familiarity with iOS development. Experience with Swift, Xcode, iOS SDK, UIKit, or SwiftUI can help developers work effectively when native functionality is required. Knowledge of native module development in React Native is useful for applications that combine cross-platform and platform-specific capabilities.

Applicants should understand REST API integration, JSON data handling, authentication concepts such as OAuth and JWT, and third-party SDK integration. Experience with Git-based source control and collaborative development workflows is also expected.

Testing knowledge is important. Relevant experience includes Jest, React Native Testing Library, unit testing, integration testing, UI testing, and other approaches used to validate mobile applications.

Preferred Skills

The posting values experience with Objective-C, CocoaPods, Swift Package Manager, SwiftUI, Fastlane, SonarQube, GitHub, GitLab, and CI/CD pipelines. Exposure to AWS, Azure, or other cloud-native application environments is also useful.

Additional strengths include mobile application security, DevSecOps practices, security scanning, biometric authentication using Face ID or Touch ID, mobile analytics, crash reporting, App Store release processes, and mobile performance optimization.

Experience in banking or financial services applications can be beneficial because the role operates within a technology environment where security, risk management, controls, and reliable software delivery are important.
