Job description
Job Summary We are looking for a skilled and experienced Node.js and MongoDB Developer with a minimum of 3 to 5 years of hands-on experience in developing server-side applications. The ideal candidate should have expertise in building scalable, high-performance backend systems, be proficient in JavaScript/TypeScript, and have a solid understanding of RESTful APIs, microservices architecture, and databases. Key Responsibilities • Develop and maintain high-performance, scalable backend services using Node.js. • Design and implement RESTful APIs and microservices. • Work with MongoDB to design and optimise database schemas, queries, and performance. • Apply strong Data Structures and Algorithms knowledge to solve complex challenges in system design and performance optimization. • Architect and implement solutions using serverless technologies like AWS Lambda, Azure Functions, or Google Cloud Functions. • Handle complex error handling and debugging to ensure a seamless user experience and uptime. • Implement caching solutions to improve performance using technologies like Redis or Memcached. • Implement email and SMS functionalities using third-party services like SendGrid, Twilio, etc. • Collaborate with front-end developers to ensure seamless integration with backend services. • Participate in code reviews, ensure adherence to coding standards, and share best practices with the team. • Debug and resolve production issues and implement long-term fixes. • Stay updated with the latest industry trends and integrate new technologies and techniques into existing systems. • Contribute to the CI/CD pipeline and improve the development process. Requirements • 3 to 5 years of experience in backend development with Node.js. • Strong knowledge of MongoDB: data modelling, indexing, aggregation, and performance optimization. • Expertise in Data Structures and Algorithms (DSA) with a proven ability to implement and optimise for performance and scalability. • Experience with building and consuming RESTful APIs. • Familiarity with microservices architecture and distributed systems. • Experience with serverless architecture and building solutions using services like AWS Lambda, Azure Functions, or Google Cloud Functions. • Knowledge of asynchronous programming and event-driven architecture in Node.js and handling multiple communication protocols (HTTP, WebSockets, MQTT, etc.). • Experience with sending email and SMS notifications using services like SendGrid, Twilio, or similar. • Familiarity with error handling techniques, debugging tools, and best practices for ensuring high uptime. • Expertise in caching technologies like Redis, Memcached, and strategies for improving system performance. • Familiarity with unit testing frameworks such as Mocha, Jest, or Chai, with the ability to write comprehensive test cases for backend code. • Experience with version control systems like Git. • Understanding of NoSQL principles and practices. • Proficiency in working with Docker, Kubernetes, or other containerization tools is a plus. • Familiarity with AWS, Azure, or other cloud platforms is a plus. • Good understanding of security best practices (encryption, authorization, and authentication). • Strong problem-solving skills, with a focus on optimising algorithms and data handling. • Ability to work independently or as part of a team. Skills: node.js,aws,mongodb
