Developer - Flutter With iOS

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.

• Degree in Computer Science or a related field

• You have prior experience as an iOS Developer

• You have a portfolio of released applications on the App Store

• You are familiar with mobile product and design lifecycles

• You have proven experience in iOS development in either Objective-C / Swift

• Experience with iOS frameworks

• Proficient understanding of code versioning tools (eg. Git)

• Familiarity with various testing tools

• You are a problem solver with good analytical skills

• Build pixel-perfect, buttery smooth UIs across both mobile platforms.
• Leverage native APIs for deep integrations with both platforms.
• Diagnose and fix bugs and performance bottlenecks for performance that feels native.
• Reach out to the open-source community to encourage and help implement mission-critical software fixes—React Native moves fast and often breaks things. 
• Maintain code and write automated tests to ensure the product is of the highest quality.
• Transition existing React web apps to React Native. 

• Have experience  in iOS/Android apps  with Flutter. Either deployed on the AppStore/Google Play or available on Github;
• 3+ years in mobile software development minimum.
• Two year’s developing Flutter applications for mobile
• Experience with third-party libraries and APIs;
• Understanding of the Agile development life-cycle;
• Experience with automated testing and building;
