MERN Developer

As a MERN Developer, you will be a full-time, on-site member of our Delhi NCR team, owning the design, implementation and maintenance of our core server-side systems. You’ll work in a fast-paced, growth-stage startup environment—with blurred lines between Dev, Ops and Product—to build scalable, secure and high-performance APIs that power both web and mobile clients.

Key Responsibilities

Architecture & Development

• Design, develop, and maintain backend applications using Node.js, Express.js, and MongoDB.
• Build and document RESTful/GraphQL APIs for web (React) and mobile (Flutter) clients.
• Follow clean-code and OOP principles in all backend implementations.

Database & Performance

• Model and optimize MongoDB schemas and manage migrations.
• Perform query optimization and debugging for performance tuning.
• Implement caching, job queues, and conduct load testing as needed.

Cloud Infrastructure

• Deploy, monitor, and maintain backend services on cloud platforms (AWS, Heroku, Vercel).
• Define Infrastructure-as-Code with Docker or serverless tools.

AI/ML & Real-Time Features

• Build real-time chat/notification services using Socket.IO or WebSockets.
• Collaborate with data teams to integrate AI/ML models via inference APIs.
• Integrate third-party APIs, payment gateways, or webhooks.

Quality & Security

• Enforce web-security best practices (OWASP, input validation, encryption)
• Set up and maintain CI/CD pipelines, perform unit/integration tests (Jest, Mocha, etc.).
• Maintain version control workflows using Git.

Collaboration & Mentorship

• Work closely with frontend (React) and mobile (Flutter) teams for API contract design.
• Participate in code reviews, documentation, and knowledge-sharing sessions.
• Mentor junior engineers and drive code reviews, documentation and knowledge sharing

MUST have qualification

• 4+ years of backend experience with the MERN stack (Node.js, Express.js, MongoDB, React exposure desirable).
• Bachelor’s degree in Computer Science, Software Engineering or a related field
• Proficiency in JavaScript (ES6+), OOP, asynchronous programming, and API construction.
• Hands-on experience with MongoDB and schema design.
• Proven track record building and securing RESTful or GraphQL APIs
• Hands-on AWS experience (EC2, RDS, S3, Lambda) and IaC (Terraform/CloudFormation)
• Solid understanding of web security best practices (OWASP Top 10, HTTPS, CSRF/XSS mitigation)
• Experience with version control workflows (Git) and setting up CI/CD
• Demonstrated ability to thrive in a growth-stage startup environment

Preferred Skills

• Real-time frameworks: Node.js/Express.js with Socket.IO or Pusher.
• Containerization (Docker) and orchestration (Kubernetes)
• Exposure to AWS, Vercel, Heroku, or similar platforms for cloud deployment
• Experience with integrating third-party APIs.
• NoSQL databases (MongoDB, DynamoDB)
• Serverless architectures (AWS Lambda, API Gateway)
• AI/ML model deployment and inference pipelines
• Prior work in electronics, logistics, or customer service support domains.
