7 skills to look for while hiring React native developers

A strong React Native developer combines JavaScript expertise with mobile-specific skills, including native iOS and Android development, React Native tooling, clean coding practices, third-party integrations, performance optimization, and communication. Businesses should evaluate these skills through practical assessments or hire pre-vetted React Native developers who meet their project requirements.

React Native allows developers to build applications for Android and iOS using JavaScript or TypeScript and React's component-based approach.

However, building reliable mobile applications requires more than understanding React components. Developers must also work with native platform features, external APIs, development tools, and device-specific performance requirements.

This guide covers seven essential React Native developer skills, what each skill involves, and how to evaluate candidates before hiring.

7 Essential React Native Developer Skills

The following checklist outlines the technical and soft skills to look for in a React Native developer.

1. In-Depth JavaScript and TypeScript Knowledge

JavaScript is the foundation of React Native development. Developers must understand how to write, organize, and maintain JavaScript code for mobile applications.

Strong candidates should demonstrate knowledge of modern JavaScript concepts, including functions, objects, arrays, promises, asynchronous operations, and ES6+ syntax.

They should also understand React fundamentals such as components, props, state, hooks, and event handling.

What to look for:

• Strong JavaScript fundamentals and ES6+ syntax.
• Experience with TypeScript for type-safe application development.
• Understanding of React components, hooks, props, and state.
• Knowledge of asynchronous programming and API requests.
• Familiarity with component-based application architecture.

Basic HTML and CSS knowledge can be useful for developers working across web and mobile projects. However, React Native uses native components and a different styling model, so web styling expertise is not a substitute for mobile development experience.

How to evaluate this skill: Ask candidates to build a simple React Native component that retrieves API data, displays results, and handles loading and error states.

Review their code structure, state management, and approach to asynchronous operations.

2. Native iOS and Android Development Knowledge

React Native supports cross-platform mobile development, but developers still need to understand the differences between Android and iOS.

Mobile applications may require access to device cameras, location services, notifications, biometric authentication, or other platform-specific features.

Developers should understand how React Native interacts with native platform APIs and when native code may be required.

What to look for:

• Familiarity with Android and iOS application development.
• Understanding of Kotlin or Java for Android development.
• Knowledge of Swift or Objective-C for iOS development.
• Experience integrating native platform APIs.
• Awareness of platform-specific UI behavior and permissions.
• Understanding of Android Studio and Xcode.

Not every React Native developer needs advanced expertise in all native languages. However, candidates working on complex integrations should understand how to troubleshoot platform-specific issues.

How to evaluate this skill: Ask candidates to explain how they would integrate camera access, push notifications, or biometric authentication into a React Native application.

Evaluate whether they understand platform permissions, native dependencies, and differences between Android and iOS.

3. React Native Tools and Technologies

React Native developers work with several tools for navigation, testing, animation, monitoring, and application delivery.

The exact tools depend on the project's architecture and requirements.

However, candidates should understand the purpose of commonly used technologies and demonstrate practical experience with relevant tools.

Important React Native tools include:

Developers should also understand the React Native New Architecture, including its modern rendering and native-module systems.

Knowledge of these concepts becomes particularly important when upgrading applications or integrating native dependencies.

How to evaluate this skill: Ask candidates which tools they used in previous projects and why they selected them.

Focus on practical experience rather than expecting familiarity with every tool.

4. Writing Clean and Maintainable Code

Writing functional code is important, but maintaining that code becomes equally significant as applications grow.

React Native developers should follow consistent coding standards and organize components so other team members can understand and modify them.

Clean code helps reduce duplication, simplify debugging, and support long-term application maintenance.

What to look for:

• Readable and consistently formatted code.
• Reusable components with clear responsibilities.
• Meaningful naming conventions.
• Appropriate separation of application logic and UI.
• Familiarity with ESLint, Prettier, and team coding standards.
• Experience with Git, pull requests, and code reviews.
• Understanding of testing and error-handling practices.

Developers should also know when to simplify components or extract reusable logic into custom hooks.

How to evaluate this skill: Review a previous project or provide a short code-refactoring exercise.

Ask candidates to identify duplicated logic, improve component organization, and explain their decisions.

5. Managing Third-Party Dependencies and APIs

Most mobile applications rely on external libraries, services, and APIs.

React Native developers must understand how to integrate these dependencies while maintaining application stability and security.

For example, an application may require payment processing, authentication, analytics, maps, or push notifications.

Some integrations work directly through JavaScript packages, while others require native modules or platform-specific configuration.

What to look for:

• Experience integrating third-party React Native libraries.
• Understanding of REST APIs and JSON data handling.
• Familiarity with GraphQL when relevant.
• Knowledge of native modules and platform-specific dependencies.
• Experience managing npm or Yarn packages.
• Awareness of library compatibility, maintenance, and security.
• Ability to handle API errors, authentication, and network failures.

Candidates should understand how to evaluate a library before introducing it into an application.

This includes reviewing maintenance activity, documentation, compatibility, and the project's technical requirements.

How to evaluate this skill: Ask candidates how they would integrate an external API or native SDK.

Evaluate their approach to dependency selection, error handling, platform compatibility, and testing.

6. Performance Optimization and On-Device Debugging

React Native applications must perform reliably across devices with different hardware capabilities and operating systems.

Developers should know how to investigate slow screens, unresponsive interactions, memory issues, and application crashes.

Performance optimization requires understanding both React rendering behavior and mobile-specific constraints.

What to look for:

• Experience testing applications on physical Android and iOS devices.
• Understanding of unnecessary component re-renders.
• Ability to optimize long lists and complex screens.
• Familiarity with React Native debugging and profiling tools.
• Knowledge of memory usage and application startup performance.
• Experience investigating crashes and platform-specific issues.
• Understanding of performance implications when using animations or native modules.

Developers should measure performance problems before applying optimizations.

They should also test important user interactions on devices representative of the intended audience.

How to evaluate this skill: Present a scenario where a React Native application becomes slow while scrolling through a large product list.

Ask candidates how they would identify the cause, measure performance, and improve the experience.

7. Communication and Problem-Solving Skills

Technical expertise alone does not guarantee successful mobile development.

React Native developers frequently collaborate with designers, backend engineers, testers, and project managers.

They must communicate technical requirements clearly, respond to feedback, and resolve development challenges.

Important soft skills include:

• Clear written and verbal communication.
• Logical problem-solving.
• Collaboration with cross-functional teams.
• Ability to explain technical decisions.
• Adaptability when project requirements change.
• Time management and accountability.
• Willingness to learn new tools and development practices.

Problem-solving is especially important when developers encounter unexpected crashes, integration failures, or platform-specific behavior.

Strong candidates should be able to investigate issues systematically rather than relying on trial and error.

How to evaluate this skill: Ask candidates to describe a difficult technical problem they encountered.

Discuss how they investigated the issue, communicated with teammates, and reached a solution.
