• 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).
