As a Senior React Developer, you will play a crucial role in developing and maintaining a React library, building scalable design systems, and collaborating with cross-functional teams to ensure a seamless and cohesive user experience across our applications. You will be responsible for creating reusable components, optimizing performance, and ensuring consistency across the front-end architecture. If you're passionate about building robust and scalable front-end applications and design systems, this is the perfect opportunity for you!

• Develop and maintain React libraries: Create reusable, modular, and well-documented React components and libraries for use across different projects.
• Build scalable design systems: Lead the design and implementation of a scalable, flexible React-based design system that ensures consistency, reusability, and ease of maintenance across multiple applications.
• Component Architecture: Design and implement UI components that are reusable, performant, and accessible, ensuring a high-quality user experience.
• Collaboration: Work closely with product managers, designers, and other engineers to understand product requirements and translate them into functional, efficient, and visually appealing user interfaces.
• Code Quality and Best Practices: Advocate for and implement coding standards and best practices for React development, including performance optimization, state management, and testing.
• Mentorship: Mentor junior and mid-level developers on React best practices, component architecture, and scaling design systems. Conduct code reviews and provide constructive feedback.
• Performance Optimization: Analyze and optimize React applications for performance bottlenecks, memory leaks, and slow rendering times.
• Continuous Improvement: Stay up to date with the latest React advancements, libraries, and tools, and implement best practices and new technologies where applicable.
• Documentation: Ensure that all components and libraries are properly documented, both for internal use and for any external developers using the library.

• Proven experience as a React Developer with 4+ years of hands-on experience in developing React-based applications.
• Experience in building reusable React components and libraries that can be shared across multiple projects.
• Deep understanding of React design patterns such as component-based architecture, hooks, and state management (e.g., Redux, Context API).
• Extensive experience with CSS and design systems: Familiarity with CSS-in-JS (e.g., styledcomponents), SCSS, and working knowledge of design system tools (e.g., Storybook).
• Experience in building and maintaining scalable, enterprise-level design systems: You should have a track record of implementing design systems that scale effectively across teams and projects.
• Strong proficiency in JavaScript (ES6+) and TypeScript.
• Experience with testing frameworks (e.g., Jest, React Testing Library, Cypress) and a strong focus on unit, integration, and UI testing.
• Experience with performance optimization: Skilled in techniques for improving React app performance, including lazy loading, memorization, code splitting, and tree shaking.
• Version control systems: Proficient in Git and related tools for source code management and collaboration.
• Strong problem-solving skills, ability to identify, diagnose, and solve complex technical challenges.
• Excellent communication skills: Ability to explain complex technical concepts to non-technical stakeholders and collaborate effectively within cross-functional teams
