Senior React Native Developer information

What does a senior React Native developer do?

A Senior React Native Developer is responsible for designing, building, and maintaining mobile applications using the React Native framework. They lead the development process, mentor junior developers, and ensure code quality through best practices and code reviews. Additionally, they collaborate with designers and backend engineers to deliver seamless, high-performance apps for both iOS and Android platforms. Their expertise allows them to solve complex problems, optimize app performance, and stay updated with the latest mobile development trends.

What are the key skills and qualifications needed to thrive as a senior React Native developer, and why are they important?

To thrive as a Senior React Native Developer, you need advanced proficiency in JavaScript, React Native, mobile app architecture, and a solid understanding of iOS and Android development, typically supported by a degree in computer science or related experience. Expertise with tools like Redux, TypeScript, RESTful APIs, and familiarity with CI/CD systems or relevant certifications is highly valued. Strong problem-solving, leadership, and communication skills help you collaborate effectively and mentor junior developers. These skills ensure robust, high-quality mobile applications and smooth project delivery in dynamic development environments.

What are some common challenges a senior React Native developer faces when integrating native modules into a cross-platform app?

Senior React Native Developers often encounter challenges when bridging native modules, such as ensuring seamless communication between JavaScript and platform-specific code (iOS/Android). Debugging and maintaining consistency across both platforms can be complex, especially when dealing with device-specific functionalities or third-party libraries. Collaboration with native developers is frequently required to address these issues, and strong documentation skills are essential for maintaining scalable, maintainable code. Staying up-to-date with React Native updates and community best practices can help mitigate integration issues.

What is the difference between Senior React Native Developer vs React Native Developer?

AspectSenior React Native DeveloperReact Native Developer
Required Experience5+ years, leadership skills1-3 years, entry to mid-level
CertificationsOptional, but preferredNot typically required
Work EnvironmentLeading projects, mentoringDeveloping features, coding
ResponsibilitiesArchitecting apps, team coordinationImplementing UI, fixing bugs

The main difference between a Senior React Native Developer and a React Native Developer lies in experience, responsibilities, and leadership. Senior developers often lead projects and mentor others, while React Native Developers focus on coding and feature implementation. Both roles require strong knowledge of React Native, but senior roles demand more experience and strategic input.

Role

We are looking for a Full Stack Developer who can build production software across the front end and back end.

This needs to be an AI-native developer. We are not looking for someone who has merely tried ChatGPT, Copilot, or Claude. You should have fundamentally changed how you develop software using agentic tools such as Claude Code, Cursor, or equivalent tools. The candidate must be strong with React and Redux on the front end and Java with Spring Boot on the back end. You should also be productive with either Node.js or Python.

Technology profile

Front end

Strong production experience with:

  • React
  • Redux
  • Responsive web applications
  • Component-based interface design
  • Complex state and workflow management
  • API integration
  • Automated front-end testing

React and Redux depth is particularly important. The candidate should understand how to keep state, components, and user workflows maintainable as an application grows.

Back end

Strong production experience with:

  • Java
  • Spring Boot
  • REST APIs
  • Service and business-logic design
  • Relational databases
  • Authentication and authorization
  • Integration and automated testing
  • Production troubleshooting

You should also be productive with at least one of:

  • Node.js
  • Python

Java and Spring Boot remain the primary back-end requirement. Node.js or Python expands the candidate's ability to build supporting services, automation, developer tooling, tests, and integrations.

AI-native engineering

This is a must-have, not a nice-to-have.

The candidate should use AI throughout the entire software-development lifecycle, including:

  • Turning requirements into specifications
  • Exploring and understanding existing codebases
  • Evaluating architecture and implementation options
  • Writing and refactoring code
  • Reviewing code and pull requests
  • Creating automated tests
  • Performing QA
  • Reproducing and debugging defects
  • Writing technical documentation
  • Preparing and validating releases

Your AI toolbox should extend beyond autocomplete inside an IDE. You should be comfortable using agentic command-line tools, repository-level instructions, automated browser and test tooling, and other development capabilities outside the traditional IDE.

You should understand how to:

  • Break substantial work into bounded assignments for subagents
  • Run independent investigations or implementation tasks in parallel
  • Give each agent the right context and constraints
  • Manage dependencies between agents
  • Reconcile multiple outputs into one coherent implementation
  • Identify conflicting assumptions or missing integration points
  • Manage the context window deliberately
  • Summarize long-running work without losing important decisions
  • Recognize when context has become stale or overloaded
  • Validate AI-produced work before it reaches production

The candidate remains accountable for everything that AI produces. AI mastery does not replace technical judgment.

What you would own

  • Front-end implementation: Build clear, responsive React and Redux interfaces for complex operational workflows.
  • Back-end implementation: Build APIs, integrations, and business logic using Java and Spring Boot.
  • AI-native execution: Use agents throughout specification, implementation, review, testing, debugging, and documentation.
  • Automated quality: Create meaningful unit, integration, API, and front-end tests.
  • Production readiness: Consider failure handling, observability, security, performance, and maintainability before release.
  • End-to-end delivery: Stay responsible for the capability after the initial code is written, including integration, release, production verification, and defect resolution.

Must-have experience

The ideal candidate has:

  • 7+ years of professional software-development experience
  • Mastery of an agentic development tool such as Claude Code or Cursor
  • Practical experience using AI for specifications, coding, reviews, QA, automated testing, debugging, and documentation
  • Experience orchestrating subagents or parallel AI workflows
  • A strong understanding of context-window management
  • The technical judgment to verify, correct, and take ownership of AI-generated work
  • Strong production experience with React and Redux
  • Strong production experience with Java and Spring Boot
  • Professional experience with either Node.js or Python
  • Experience building and operating customer-facing web applications
  • Experience with APIs, databases, integrations, and automated testing

Strong preference

  • Deep front-end experience with complex operational interfaces
  • Redux Toolkit or Redux-Saga experience
  • Material UI, DevExpress, or similar component-framework experience
  • B2B SaaS or recurring-revenue product experience
  • Cloud-native application experience
  • Experience with distributed services or event-driven workflows
  • Experience with automated browser, API, integration, and contract testing
  • Production observability and incident-response experience
  • Experience in logistics, security, IoT, video, computer vision, or workflow automation
  • Created reusable AI instructions, agent workflows, development guardrails, or evaluation methods


This role will require the candidate to complete background checks (includes but not limited to: references, educational verification, criminal check, credit check - where applicable). Certain roles may also require testing.
