React JS Developer

Job Title: Senior ReactJS Developer (Frontend & Scalable Systems)

Role Overview

We are looking for an exceptional ReactJS Developer (3 to 8 years of exp.) with a deep understanding of JavaScript and modern web architectures. You won't just be building UI components; you will be responsible for architecting scalable frontend systems, managing complex states, and ensuring seamless integration with sophisticated backend services. The ideal candidate has a "full-stack mindset" and understands how data flows from the database to the end user.

Key Responsibilities

• Frontend Architecture: Design and implement highly scalable, modular, and reusable UI components using ReactJS.
• State Management: Lead the strategy for complex state management (using Redux, Recoil, or React Context) to ensure high performance in data-heavy applications.
• API Integration: Architect the data-fetching layer to interact with RESTful and/or GraphQL APIs, ensuring efficient caching and error handling.
• Performance Optimization: Diagnose and resolve rendering bottlenecks and optimize application load times for a seamless user experience.
• Full-Stack Collaboration: Partner with backend engineers to define API contracts and understand system constraints to build end-to-end features.
• Code Quality: Enforce high standards through unit testing (Jest/RTL), integration tests (Cypress/Playwright), and rigorous code reviews.

Technical Requirements

• JavaScript Mastery: Expert-level knowledge of ES6+, TypeScript, and functional programming patterns.
• React Ecosystem: Proficiency in React (Hooks, Suspense, Lazy Loading) and modern build tools (Vite, Webpack, or Next.js).
• Styling & UX: Deep experience with CSS-in-JS (Styled Components/Emotion) or utility-first frameworks like Tailwind CSS.
• Backend Awareness: Strong understanding of backend technologies (Node.js, Python, or Java) and how they interact with the frontend.
• API Knowledge: Expertise in handling asynchronous requests, WebSockets for real-time data, and authentication protocols (OAuth, JWT).
• Tools: Proficiency with Git, CI/CD pipelines, and cloud-based deployment (AWS/Vercel/Firebase).

Preferred Qualifications

• Experience building Micro-frontends or managing large Monorepos.
• Familiarity with Server-Side Rendering (SSR) and Static Site Generation (SSG) via Next.js.
• A strong portfolio of building applications that handle massive traffic or large-scale data visualization.
