MERN Stack Developer

Location: Surat, Gujarat (No WFH )

Job Summary:

We are looking for a Full Stack Developer (MERN) with hands-on experience in building highly scalable, performance-driven applications. The ideal candidate should have a deep understanding of both front-end and back-end development, microservices, and database optimization for large-scale systems. You will be responsible for designing, developing, and maintaining applications that can handle high concurrency (1,000+ active users) while ensuring performance, reliability, and scalability.

This role involves working closely with cross-functional teams — including product managers, designers, and DevOps engineers — to deliver cutting-edge, enterprise-grade solutions.

Roles & Responsibilities:

- Design and develop scalable and distributed web applications using the MERN stack (MongoDB, Express.js, React/Next.js, Node.js).
- Build and optimize RESTful APIs for high-performance, concurrent environments.
- Architect and manage MongoDB databases, ensuring high availability, effective query performance, and scalability.
- Implement queueing systems (e.g., BullMQ, RabbitMQ, Kafka, or Redis Queues) for background jobs and asynchronous processing.
- Optimize server and client performance to support real-time data updates and high concurrent user loads.
- Collaborate with DevOps to improve deployment pipelines, containerization (Docker), and cloud scalability.
- Conduct thorough testing, profiling, and debugging to identify performance bottlenecks and optimize both code and infrastructure.




- Participate in code reviews, architecture discussions, and sprint planning to ensure technical excellence and scalability across all layers.

Qualification / Requirements:

- Bachelor’s degree in Computer Science, Engineering, or related field (or equivalent experience).
- 1 + years of hands-on experience in full-stack development using the MERN stack.
- Proven experience working on applications supporting 1,000+ concurrent users or large-scale distributed systems.
- Strong expertise in:
- Node.js (asynchronous programming, clustering, performance optimization)
- Next.js & React.js (SSR, CSR, and dynamic rendering)
- MongoDB (aggregation pipelines, indexing, schema design for scalability)
- Practical experience with message queues (BullMQ, RabbitMQ, Kafka, or Redis Streams).
- Familiarity with caching mechanisms (Redis, Memcached) to optimize performance.
- Experience with Docker and microservices-based architectures is a plus.
- Good understanding of API design, authentication mechanisms (JWT, OAuth), and security best practices.
- Experience working in Agile environments and using Git-based version control.

Nice to Have:

- Exposure to serverless computing (AWS Lambda).
- Experience with monitoring tools (New Relic, Datadog, ELK Stack).
- Knowledge of CI/CD pipelines and automated deployment workflows.
- Experience in real-time communication (WebSockets, Socket.io).

Skills:- MongoDB, React.js, NextJs (Next.js), NodeJS (Node.js), RESTful APIs, RabbitMQ and Redis
