Senior React Native Developer

Job description

Overview

Senior React Native Developer is a highly experienced and skilled software developer responsible for designing, developing, and maintaining robust, high-performance, and scalable mobile applications for both iOS and Android platforms using React Native.

This role requires a deep understanding of mobile development principles, strong expertise in modern JavaScript/TypeScript and React Native, and a solid grasp of software engineering best practices.

You will play a key role in the full mobile application development lifecycle, from technical design and feature implementation to deployment and ongoing optimization.

Experience with back-end technologies, particularly the .NET stack, is a plus but not required.

What You'll Be Doing

• Mobile Application Development: Design, develop, and implement complex features and user interfaces for high-quality, cross-platform mobile applications using React Native.
  
  
• React Native & JavaScript/TypeScript Expertise: Demonstrate strong proficiency in React Native, React, JavaScript (ES6+), and TypeScript.
  
  Expertise in state management libraries (e.g., Redux, MobX, Recoil) is essential.
  
  
• Front-End Development: Focus on creating exceptional user experiences (UX), fluid performance, and responsive design, ensuring cross-device compatibility and adherence to mobile platform guidelines.
  
  
• Native Module Integration: Experience with integrating and developing native modules (iOS/Swift/Objective-C or Android/Java/Kotlin) to bridge React Native with platform-specific capabilities when necessary.
  
  
• API Development & Integration: Integrate mobile applications with back-end services via RESTful APIs or GraphQL.
  
  Experience in back-end technologies, like .NET Core/C#, is a welcome bonus.
  
  
• Performance Optimization: Profile and optimize mobile application performance, including memory usage, startup time, and UI rendering speed, on both iOS and Android.
  
  
• Testing & Quality Assurance: Write and implement unit, integration, and end-to-end tests (e.g., using Jest, Enzyme, or testing-library) to ensure code quality, application stability, and reliability.
  
  
• Deployment & Maintenance: Manage the mobile application release lifecycle, including store submissions (Apple App Store and Google Play Store).
  
  Implement and maintain CI/CD pipelines for mobile builds (e.g., using Fastlane, Azure DevOps, or AWS Amplify).
  
  
• Code Reviews & Mentoring: Actively participate in code reviews, enforce coding standards, and share best practices across the team.
  
  Mentor and guide junior developers in mobile development techniques.
  
  
• Requirements Analysis & Technical Design: Collaborate with product managers, designers, and stakeholders to refine requirements, assess technical feasibility, and translate them into robust technical designs and architectural decisions.
  
  
• Problem Solving & Debugging: Troubleshoot and debug complex issues across the mobile stack, including performance bottlenecks and platform-specific bugs.
  
  
• Agile Development: Work effectively within an Agile/Scrum environment, participating in all relevant ceremonies (sprint planning, daily stand-ups, retrospectives).
  
  

Key Skills

• Extensive experience with React Native for building production-grade iOS and Android applications.
  
  
• Strong proficiency in modern JavaScript (ES6+) and TypeScript.
  
  
• Deep understanding of React and its core principles (e.g., component lifecycles, hooks, state management).
  
  
• Experience with mobile performance profiling and optimization techniques.
  
  
• Proficiency in integrating with RESTful APIs or GraphQL.
  
  
• Familiarity with native mobile development environments (Xcode, Android Studio) and the mobile CI/CD process.
  
  
• Experience with testing frameworks (e.g., Jest, React Native Testing Library).
  
  
• Strong understanding of software design patterns and best practices.
  
  
• Excellent problem-solving, analytical, and debugging skills.
  
  
• Strong communication and collaboration skills; ability to work independently and as part of a team.
  
  
• Experience with Agile development methodologies.
  
  
• (Optional): Experience with back-end technologies such as .NET Core (C#), and related tools (e.g., Entity Framework, SQL Server).
