React Native Developer

About Flutter Developer: 

We are looking for a Flutter and NodeJS developer with experience in building and publishing apps for iOS 

and Android. 

Your primary focus will be the development of mobile applications and the development / integration with back-end services. You will be working alongside other engineers and developers working on different layers of the infrastructure. Therefore, a commitment to collaborative problem solving, sophisticated design and the creation of quality products is essential. 

We are a fluid organization, and there will sometimes be expectations of tasks beyond the stated job description. For instances, you may be asked to assist with testing other functionalities, or to assist with a production support incident. Changing customer priorities will also mean switching out of an unfinished task to focus on a higher- priority task. 

Roles & Responsibilities: 

* Designing and building mobile applications using Flutter frameworks. 

* Working closely with other technical specialists for the technical architecture of features.

* Collaborating with and guiding other team members to define app features and dependencies. 

* Ensuring the quality and performance of the application to specifications.

* Identifying potential problems and resolving application performance bottlenecks.

 * Publishing application on Apple App Store and Google Play Store. 

* Designing and implementing application updates.

Prerequisites: 

* Experience in development of Android/iOS applications and have deployed them on Google Play/AppStore. 

* In depth understanding of Object-oriented programming languages like Java and C++. * Experience in the Flutter framework. 

* Experience in Dart programming, developing and integration of Rest APIs, GetX state management, Firebase Cloud Messaging API, working with Map APIs, Caching Data using Hive and integration of payment gateways. 

* Comfortable using test cases for debugging code, enhancing performance and reliability.

* Experience in developing Rest APIs using NodeJS and MongoDB. 

* Familiarity using version control tools like Git and IDEs like Android Studio, VS Code etc.

Responsibilities

1. Cross-Platform Mobile Development

• Build, maintain, and scale production-grade React Native applications for both Android and iOS platforms from a single codebase.
• Translate product requirements and UX designs into clean, modular, and reusable React Native components.
• Develop rich, intuitive user interfaces for AI/ML dashboards, real-time analytics, and consumer-facing applications.
• Own features end-to-end — from technical design through to deployment on Play Store and App Store.

2. Native Integration & Bridging

• Write custom native modules and bridges in Kotlin/Java (Android) or Swift/Objective-C (iOS) to extend React Native's capabilities where required.
• Integrate third-party SDKs, device hardware APIs, and platform-specific features seamlessly into the React Native layer.
• Ensure consistent functionality and behaviour across a wide range of Android and iOS devices and OS versions.

3. Real-Time & Data-Driven UI

• Build real-time UI components that handle live data streams, WebSocket connections, and high-frequency data updates with minimal latency.
• Develop data-intensive views including charts, dashboards, and monitoring interfaces optimised for mobile performance.
• Ensure smooth, responsive user experiences under high-traffic and data-heavy conditions.

4. Performance & Optimization

• Profile, debug, and optimize application performance using tools such as Flipper, Hermes, React DevTools, and platform-native profilers.
• Minimize app bundle size, reduce render cycles, and improve startup time through best-in-class optimization techniques.
• Ensure accessibility compliance and cross-device UI consistency across varying screen sizes and resolutions.

5. Architecture & Code Quality

• Design and implement scalable mobile architectures supporting modularity, testability, and long-term maintainability.
• Implement robust state management using Redux, Zustand, MobX, or React Context depending on application complexity.
• Establish and uphold mobile coding standards, component libraries, and reusable design systems across the team.

6. Collaboration & Delivery

• Partner closely with backend, AI/ML, data engineering, and design teams to integrate APIs, data pipelines, and workflows.
• Actively participate in code reviews, sprint ceremonies, and technical design discussions.
• Support CI/CD pipelines using Fastlane, Bitrise, or equivalent tools for automated builds and releases.
• Contribute to OTA update strategies using CodePush or equivalent.

Required Skills & Qualifications

• Strong hands-on experience building and shipping production React Native applications on both Android and iOS.
• Proficiency in JavaScript and TypeScript — TypeScript strongly preferred.
• Experience with state management libraries — Redux, Zustand, MobX, or Context API.
• Solid understanding of React Native architecture — Bridge, JSI, Hermes engine, and the New Architecture (Fabric/TurboModules) is a plus.
• Experience writing native modules or bridges in either Kotlin/Java or Swift/Objective-C.
• Hands-on experience with REST APIs, GraphQL, and WebSockets in a mobile context.
• Strong understanding of mobile UI/UX principles, responsive design, and platform-specific design guidelines (Material Design & HIG).
• Experience with CI/CD pipelines and app store deployment processes.

Preferred Skills

• Experience building data-intensive or dashboard-heavy mobile applications.
• Familiarity with data visualization libraries such as Victory Native, Recharts, or D3.js for mobile.
• Exposure to AR/VR or graphics-intensive mobile experiences (ARKit, ARCore, React Native Vision Camera).
• Experience with OTA updates via CodePush or similar tools.
• Familiarity with monorepo setups (Nx, Turborepo) for managing shared mobile codebases.
• Understanding of accessibility standards (WCAG) and inclusive design on mobile.
• Exposure to AI/ML integration on mobile — on-device inference, TensorFlow Lite, or CoreML.
