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.
