• Experience with Firebase, push notifications, and app deployment on iOS & Android.
• Familiarity with native mobile development (Kotlin/Java or Swift/Obj-C) is a plus.
• Proficient in Git and Agile methodologies with excellent problem-solving skills.

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
