About the Role

We are seeking an experienced React Developer with strong expertise in building high-quality, scalable, and fault-tolerant web applications. The ideal candidate will have deep knowledge of React architecture, modern JavaScript/TypeScript, and best practices for clean, maintainable code. You will be responsible for developing modular, reusable micro-components and ensuring the stability of the application even when individual components encounter failures.

Key Responsibilities

• Design and develop responsive, performant, and secure React applications.
• Write clean, readable, and maintainable code following modern development practices (SOLID, DRY, KISS).
• Architect and implement micro-component structures to ensure that a single component failure does not affect the overall system.
• Integrate efficiently with RESTful and GraphQL APIs, ensuring optimized data flow and error handling.
• Implement robust error boundaries and fallback mechanisms for UI resilience.
• Ensure high standards of code quality, testing, and documentation.
• Collaborate closely with backend, DevOps, and design teams to ensure smooth integration and performance optimization.
• Participate in code reviews, mentoring, and continuous improvement initiatives.
• Proactively identify and resolve technical issues, performance bottlenecks, and UX problems.

Required Qualifications:

• 4+ years of professional experience with React.js and related technologies.
• Strong proficiency in JavaScript (ES6+) and TypeScript.
• Deep understanding of React lifecycle, hooks, context API, and state management libraries (Redux, Recoil, Zustand, etc.).
• Experience in building fault-tolerant UIs using React Error Boundaries and fallback strategies.
• Hands-on experience integrating with RESTful or GraphQL APIs and handling async operations gracefully.
• Solid grasp of frontend architecture, component isolation, and micro frontends.
• Knowledge of unit testing (Jest, React Testing Library) and CI/CD pipelines.
• Experience with performance optimization and security best practices.
• Excellent problem-solving skills, attention to detail, and a mindset for writing efficient, production-grade code.

Nice to Have

• Experience with Next.js or React Native.
• Understanding of containerized deployments (Docker, Kubernetes).
• Familiarity with design systems.

Soft Skills

• Strong communication and collaboration abilities.
• Passion for continuous learning and innovation.
• Ability to work independently and take ownership of projects.
• Strong sense of responsibility for system reliability and user experience.
