Find The RightJob.

We are looking for a MERN Stack Developer with 2+ years of real-world experience who thinks beyond CRUD APIs and UI screens. This role is for someone who understands how full-stack systems are designed , cares about scalability, performance, security, and clean architecture , and takes ownership of features end-to-end .

We value ownership, speed, clean code, and smart problem-solving . If you enjoy building products from scratch, thinking in systems, and shipping meaningful features—not just “finishing tasks”—this role is for you.

🧠 Key Responsibilities

  • Design, develop, and maintain full-stack applications using MongoDB, Express, React, and Node.js
  • Build scalable and maintainable backend APIs with proper validation, error handling, and security
  • Develop clean, reusable, and performant React components
  • Design database schemas and optimize queries for performance and scalability
  • Translate product and business requirements into solid technical solutions
  • Design frontend and backend architecture that can scale as the product grows
  • Handle authentication, authorization, roles, and permissions
  • Work with async operations, background jobs, and API integrations
  • Manage application state properly (React state, context, or state libraries)
  • Handle edge cases: loading, failure states, retries, and fallbacks
  • Write clean, readable, and well-structured JavaScript / TypeScript code
  • Follow and continuously improve coding standards and best practices
  • Debug production issues using logs, reasoning, and root-cause analysis
  • Review PRs, give constructive feedback, and contribute to team learning
  • Work with designers to deliver good UX, not just “working UI”
  • Collaborate closely with QA, design, and product teams
  • Think ahead—identify technical debt, performance bottlenecks, and improvement areas
  • Use AI tools responsibly to speed up development, debugging, and learning (with understanding)

✅ Qualifications Must Have

  • 2+ years of hands-on experience with the MERN stack
  • Strong knowledge of JavaScript and TypeScript, including OOP concepts
  • Solid experience with Node.js & Express
  • Hands-on experience with MongoDB, schema design, indexing, and aggregation
  • Experience building and consuming REST APIs
  • Strong understanding of async/await, promises, event loop
  • Knowledge of HTML, CSS, responsive design (Tailwind / Bootstrap preferred)
  • Experience with React hooks, component lifecycle, and state management
  • Use React performance optimizations such as: React.memo useCallback, useMemo
  • Implement code splitting and lazy loading using dynamic imports
  • Work on or understand micro-frontend architecture and module federation
  • Experience handling authentication (JWT, sessions, OAuth)
  • Familiarity with Git, code reviews, and basic CI/CD concepts
  • Exposure to real production issues (performance, bugs, scaling, failures, debugging)

Good to Have (Big Plus)

  • Knowledge of Next.js or server-side rendering concepts
  • Experience with Redis, queues (kafka, rabbitmq), or background jobs
  • Experience with Docker, cloud deployments, or Nginx
  • Understanding of performance tuning and lazy loading
  • Experience working in a startup or fast-paced environment

Who Should Not Apply

Please Do Not Apply If

  • You only focus on “closing tickets” without questioning why something is being built
  • You lack strong JavaScript fundamentals (arrays, objects, async/await, promises, event loop)
  • You mostly copy-paste code without understanding it
  • You never think about edge cases, failures, retries, or resilience
  • You depend heavily on others for architecture or technical direction
  • You avoid responsibility and say things like:
  • “Frontend issue”
  • “Backend issue”
  • “It was already like this”
  • “QA didn’t catch it”
  • You are not comfortable explaining your code, decisions, or design choices
  • You expect exact step-by-step instructions for every task
  • You are not interested in learning and improving as a full-stack engineer

👉 This role is not for task executors .

We want problem solvers, thinkers and owners .

Skills:- MERN Stack, React.js, NodeJS (Node.js), Express, MongoDB, HTML/CSS, Javascript, Data Structures, Debugging, API and RESTful APIs
