Javascript Developer Node.js

As a backend developer at our company, you will be responsible for building and maintaining RESTful and GraphQL APIs with clear contracts, versioning, and comprehensive documentation using technologies like OpenAPI/Swagger. You will work on implementing secure, efficient, and reusable API patterns with proper error handling, input validation, and rate limiting. Integration with databases (SQL & NoSQL), message brokers (Kafka, RabbitMQ), and third-party services will be a key aspect of your role. Collaboration with frontend teams, product managers, and DevOps engineers is essential to deliver end-to-end features. Optimizing application performance, scalability, and reliability through profiling, caching, and asynchronous processing will also be part of your responsibilities. Writing unit, integration, and end-to-end tests using frameworks like Jest, Supertest, and Mocha is crucial. Participation in code reviews, CI/CD pipeline improvements, and infrastructure automation using tools like Docker, Kubernetes, AWS/GCP is expected. Staying up-to-date with emerging trends in the Node.js ecosystem and advocating for best practices is encouraged.

Key Responsibilities:

• Build and maintain RESTful and GraphQL APIs with clear contracts, versioning, and comprehensive documentation (OpenAPI/Swagger).
• Implement secure, efficient, and reusable API patterns with proper error handling, input validation, and rate limiting.
• Integrate with databases (SQL & NoSQL), message brokers (Kafka, RabbitMQ), and third-party services (payment gateways, identity providers, etc.).
• Collaborate with frontend teams, product managers, and DevOps engineers to deliver end-to-end features.
• Optimize application performance, scalability, and reliability through profiling, caching, and asynchronous processing.
• Write unit, integration, and end-to-end tests using frameworks like Jest, Supertest, and Mocha.
• Participate in code reviews, CI/CD pipeline improvements, and infrastructure automation (Docker, Kubernetes, AWS/GCP).

Qualifications Required:

• 5+ years of hands-on experience in Node.js backend development.
• Proven experience in API design and development REST, GraphQL, OpenAPI/Swagger.
• Deep understanding of asynchronous programming, event-driven architecture, and non-blocking I/O.
• Experience with Express.js, NestJS, or similar frameworks.
• Familiarity with database technologies: PostgreSQL, MongoDB, DynamoDB, or similar.
• Experience with message queues (e.g., Kafka, RabbitMQ) and event-driven systems.
• Proficiency in Git, Jenkins, Docker, and cloud platforms (AWS, GCP, Azure).
• Strong problem-solving skills and ability to work independently in a remote or distributed team.
• Excellent communication skills and a collaborative mindset.

Good to Have (Preferred):

• Hands-on experience with AWS (EC2, Lambda, S3, API Gateway, CloudWatch, IAM, CloudFormation, etc.).
• Proficiency in Python for scripting, automation, data processing, or backend integration.
• Experience with serverless architectures (AWS Lambda, Azure Functions).
• Knowledge of microservices architecture, service discovery, and distributed tracing.
• Exposure to CI/CD pipelines, infrastructure-as-code (Terraform, Ansible), and monitoring tools (Prometheus, Grafana, ELK).
• Contributions to open-source projects or technical blogs.
• Experience working with authentication/authorization systems (OAuth2, JWT, Okta, AWS Cognito).
