Node.js Developer

As a Node.js Developer, you will be responsible for building scalable, high-performance server-side applications. You will work closely with frontend developers, DevOps teams, and other stakeholders to design, develop, and maintain backend services, APIs, and microservices. Your role will involve optimizing application performance, ensuring security, and integrating databases and cloud services to deliver robust web and mobile applications.

Key Responsibilities:

  • Develop, maintain, and optimize server-side applications using Node.js.
  • Design and implement RESTful and GraphQL APIs for seamless frontend-backend communication.
  • Ensure code quality, scalability, and maintainability.
  • Work with SQL (PostgreSQL, MySQL) and NoSQL (MongoDB, Redis) databases.
  • Optimize queries and ensure data consistency across services.

Microservices & Cloud Deployment:

  • Develop and deploy microservices architecture using Docker and Kubernetes.
  • Integrate cloud services such as AWS, GCP, or Azure for storage, authentication, and serverless computing.

Security & Performance Optimization:

  • Implement authentication and authorization using JWT, OAuth, or Passport.js.
  • Ensure security best practices (e.g., input validation, data encryption, XSS/CSRF protection).
  • Optimize application performance, caching, and load balancing.

Collaboration & Version Control:

  • Work closely with frontend developers (React, Angular, Vue) to integrate APIs.
  • Use Git and CI/CD pipelines for version control and automated deployments.
  • Participate in code reviews and agile development processes (Scrum/Kanban).

Requirements:

  • Proven experience as a Node.js Developer with backend development expertise.
  • Hands-on experience with Express.js, Nest.js, or Koa.js frameworks.
  • Experience with databases (SQL & NoSQL) and ORM tools like Sequelize or Mongoose.
  • Familiarity with Docker, Kubernetes, and cloud platforms (AWS, GCP, Azure).
  • Strong knowledge of API security, authentication mechanisms, and performance tuning.

Preferred Qualifications:

  • Bachelor's degree in Computer Science, Engineering, or a related field.
  • Experience with serverless frameworks (AWS Lambda, Firebase Functions).
  • Knowledge of WebSockets, GraphQL, or message queues (RabbitMQ, Kafka).
  • Familiarity with TDD (Jest, Mocha, Chai) and CI/CD pipelines.
