Lead Node.js Developer

Key Responsibilities :

1. Architecture and System Design :

- Scalable Design : Design and implement robust, high-performance, and scalable backend services using best practices in software architecture.

- Pattern Implementation : Apply modern architectural patterns such as Domain-Driven Design (DDD), Clean Architecture, and

- Event-Driven Systems to ensure code maintainability, testability, and flexibility.

- Code Quality : Drive technical excellence and efficiency by writing clean, well-tested, and well-documented code, participating actively in code reviews.

2. API Development and Integration :

- GraphQL Expertise : Design, develop, and integrate GraphQL APIs to provide flexible and efficient data access for client applications.

- Real-time Communication : Implement and manage WebSockets for establishing and maintaining efficient real-time data communication capabilities within the application.

- REST/Microservices : Work with traditional RESTful APIs and contribute to the design of the microservices ecosystem.

- Dependency Management : Maintain and manage project dependencies and packages using standard tools like NPM and Yarn.

3. Performance and Observability :

- Monitoring Implementation : Implement and configure monitoring solutions to track system health, performance metrics, and

logs.

- Optimization : Utilize observability tools like Prometheus, Grafana, or the ELK stack (Elasticsearch, Logstash, Kibana) to monitor, analyze, and optimize backend performance and identify bottlenecks.

- Troubleshooting : Diagnose and resolve complex performance, scalability, and stability issues in production environments.

4. Cross-Functional Collaboration and Frontend Support :

- Frontend Liaison : Collaborate seamlessly with frontend engineering teams to define API contracts and data structures.

- Templating : Utilize server-side templating engines such as EJS or Handlebars for server-rendered views or micro-frontends when required.

- Basic Frontend Understanding : Leverage a basic understanding of front-end technologies such as HTML, CSS, and modern

JavaScript frameworks to facilitate effective integration and troubleshooting across the stack.

Required Technical Skills and Experience :

- Experience : 4 to 8 years of professional experience in backend software development (preferably using Node.js/JavaScript/TypeScript).

- Architecture : Hands-on experience applying and defending complex architectural patterns such as Domain-Driven Design (DDD) and Clean Architecture.

- API Technologies : Proven expertise in designing, building, and integrating production-grade GraphQL APIs.

- Real-Time : Practical experience implementing and managing WebSockets for real-time application features.

- Observability : Experience configuring and using industry-standard observability tools, specifically Prometheus, Grafana, or the ELK stack for monitoring and optimization.

- Server-side Rendering : Familiarity with server-side templating engines like EJS or Handlebars.

- Tooling : Comfort and proficiency with JavaScript package managers such as NPM and Yarn.

Qualifications : Bachelor's or Master's degree in Computer Science, Engineering, or a related technical field, or equivalent practical experience.
