About the Role

We are looking for a Senior Backend Engineer with 8–10 years of strong hands-on experience in Node.js to design, build, and scale high-performance backend systems. The ideal candidate should have strong expertise in API development, databases, distributed systems, microservices, and production-level system design.

This is a hands-on engineering role for someone who can take ownership of backend architecture, solve complex technical problems, and build reliable systems at scale.

Key Responsibilities

• Design and develop scalable backend services and REST APIs using Node.js.
• Build high-performance applications using Express.js/NestJS and TypeScript.
• Design database schemas and optimize queries across MongoDB and PostgreSQL/MySQL.
• Work with Redis for caching, concurrency, and performance optimization.
• Design and implement microservices and event-driven architectures.
• Work with Kafka/RabbitMQ for asynchronous processing and inter-service communication.
• Build real-time systems using WebSockets/Socket.io where required.
• Handle authentication, authorization, RBAC, API security, and data protection.
• Identify and resolve performance bottlenecks, memory issues, and production-level challenges.
• Design systems capable of handling high concurrency and large data volumes.
• Take ownership of backend architecture, technical decisions, development, testing, and production support.
• Collaborate with frontend, QA, DevOps, and product teams to deliver reliable solutions.
• Conduct code reviews and mentor junior/mid-level developers.
• Contribute to technical documentation, coding standards, and engineering best practices.

Required Skills & Experience

• 8–10 years of professional backend/software development experience.
• 6+ years of strong hands-on experience with Node.js.
• Strong proficiency in JavaScript/TypeScript.
• Strong experience with Express.js and/or NestJS.
• Excellent understanding of REST API design and backend architecture.
• Strong hands-on experience with MongoDB and/or PostgreSQL.
• Good knowledge of Redis, database indexing, query optimization, and transactions.
• Practical experience with Kafka, RabbitMQ, or similar messaging systems.
• Strong understanding of microservices, event-driven architecture, asynchronous processing, and concurrency.
• Experience with Docker and cloud environments such as AWS.
• Strong understanding of authentication, authorization, JWT, RBAC, and API security.
• Good understanding of Git, CI/CD, testing, debugging, and production deployments.
• Strong problem-solving and system-design skills.

Good to Have

• Experience building high-concurrency or real-time applications.
• Experience with WebSockets/Socket.io.
• Experience with AWS services, Kubernetes, or other container orchestration platforms.
• Experience with payment systems, financial platforms, CRM, or other transaction-heavy applications.
• Experience mentoring engineers and leading backend technical initiatives.

What We’re Looking For

Someone who is not just an API developer, but a strong backend engineer who understands how systems behave in production — scalability, concurrency, database performance, fault tolerance, security, and maintainability.

If you enjoy solving complex backend problems and taking ownership of systems end-to-end, we’d like to hear from you.
