Responsibilities

• Design, develop, test and deploy high-quality cross-platform mobile applications using React Native and TypeScript for iOS and Android.
  

• Take ownership of feature delivery end-to-end, from technical design through release, monitoring and post-launch iteration.
  

• Translate product requirements into clear technical specifications and design documents.
  

• Contribute to and influence the mobile architecture, including state management, navigation, offline behavior, modularization and native bridges.
  

• Work with the React Native New Architecture (Fabric, TurboModules, JSI) and Hermes to deliver performant, memory-efficient applications.
  

• Build and maintain reusable component libraries and shared modules used across multiple Foodhub brands and applications.
  

• Develop and integrate native modules in Swift and Kotlin where required, and debug native build issues across Xcode and Android Studio.
  

• Optimize application performance, including bundle size, startup time, frame rates, list virtualization, memory usage and crash rates.
  

• Implement and maintain robust automated testing using Jest, React Native Testing Library and end-to-end frameworks such as Detox or Maestro.
  

• Own and improve mobile CI/CD pipelines using tools such as Fast lane, EAS Build, App Center or equivalent.
  

• Lead code reviews with a strong focus on quality, security, accessibility and maintainability.
  

• Establish and maintain project-level AI context configurations and coding standards documentation.
  

• Mentor mid-level and junior engineers on React Native, TypeScript, mobile best practices and the responsible use of AI development tools.
  

• Collaborate closely with Product, Design, Backend, QA and EPOS/POS teams to translate business requirements into well-scoped technical solutions.
  

• Contribute to engineering standards, documentation, technical specifications and the continuous improvement of team processes.
  

Preferred Skills

• Familiarity with emerging standards such as the Model Context Protocol (MCP) and the integration of AI tooling into developer workflows is desirable.
  

Qualifications

• Minimum 5+ years of professional software engineering experience.
  

• At least 5 years of hands-on production experience building React Native applications in TypeScript.
  

• Demonstrable experience shipping and maintaining mobile applications that are live on the Apple App Store and Google Play Store.
  

Required Skills

• Strong, advanced-level TypeScript skills, including strict mode, generics, discriminated unions, utility types and disciplined API typing.
  

• Practical experience with the React Native New Architecture (Fabric, TurboModules, JSI) and the Hermes JavaScript engine.
  

• Deep understanding of React Native internals, including the bridge, lifecycle, rendering pipeline, reconciliation and threading model.
  

• Experience writing or extending native modules in Swift (iOS) and Kotlin (Android).
  

• Proficiency with modern state management approaches such as Redux Toolkit, Zustand, Jotai, MobX or React Query.
  

• Strong working knowledge of React Navigation, including deep linking, universal links, App Links and complex navigation patterns.
  

• Experience with offline-first architectures, secure local storage, push notifications, background tasks and OTA updates.
  

• Hands-on experience with mobile CI/CD pipelines using tools such as Fast lane, EAS Build, Bitrise or App Center.
  

• Strong testing discipline using Jest, React Native Testing Library and at least one end-to-end framework.
  

• Solid understanding of REST and/or GraphQL API integration, authentication flows and secure communication on mobile.
  

• Working knowledge of mobile application security best practices.
  

• Proficiency with Git and modern branching workflows.
  

• Daily, hands-on use of AI coding assistants as a core part of the development workflow.
  

• Demonstrated judgment in applying AI assistance appropriately.
