You will work on mission-critical projects, ensuring seamless user experiences and robust backend services while adhering to best practices in software engineering.

Key Responsibilities

1. Zoho CRM Development and Customization

- Design, configure, and enhance Zoho CRM modules, fields, layouts, and automation workflows
- Build and manage custom functions, blueprints, and macros using Deluge scripting.
- Integrate Zoho CRM with third-party applications and internal systems using REST APIs and webhooks.

2. Zoho Creator Application Development

- Design and develop robust, scalable custom applications on the Zoho Creator platform.
- Implement business logic through advanced Deluge scripting.
- Develop intuitive forms, reports, and dashboards while ensuring data accuracy and performance.

3. Server-Side Development & Maintenance:

- Design, develop, and maintain scalable server-side network components using Node.js, including Express.js or Koa.js frameworks for building RESTful APIs and micro services architectures.
- Implement asynchronous programming patterns, event-driven architectures, and middleware for handling complex business logic, ensuring high concurrency and fault tolerance.

4. Database Optimization & Integration:

- Ensure optimal performance of central databases (e.g., MongoDB, PostgreSQL, or MySQL) through indexing, query optimization, and schema design.
- Manage data migration, replication, and sharding strategies to handle large-scale data volumes while maintaining responsiveness to front-end requests.

5. Front-End Integration & Collaboration:

- Collaborate closely with front-end developers to integrate UI elements built with React.js,



utilizing state management libraries like Redux or Context API, and component-based architectures for reusable UI patterns.
- Optimize client-server interactions using GraphQL or REST APIs, implementing caching mechanisms (e.g., Redis) to reduce latency.

6. High-Performance Application Development:

- Write testable, reusable, and efficient code following SOLID principles, with comprehensive unit/integration testing using frameworks like Jest, Mocha, or Enzyme.
- Implement performance profiling and optimization techniques, such as code splitting, lazy loading, and memory leak detection.

7. API Development & Security:

- Build secure and efficient RESTful APIs, incorporating rate limiting, input validation, and error handling to prevent common vulnerabilities (e.g., OWASP Top 10).
- Familiarity with advanced Node.js features like cron jobs (using node-cron), event listeners (EventEmitter), and circuit breakers (e.g., using Hystrix patterns) for resilient systems.

8. Security & Data Protection:

- Implement robust security protocols, including encryption (e.g., AES for data at rest), HTTPS enforcement, and compliance with standards like GDPR or PCI-DSS.
- Design data protection measures and storage solutions, such as cloud object storage (S3) and backup strategies with versioning.

9. Testing, Troubleshooting & Support:

- Run diagnostic tests, debug defects using tools like Node Inspector or Chrome DevTools, and provide technical support for production issues.
- Monitor application health with logging frameworks (e.g., Winston, ELK Stack) and performance metrics (e.g., New Relic or Prometheus).

10. Documentation & Reporting:

- Document Node.js processes, including API endpoints, database schemas (using ER diagrams), and system architectures.
- Prepare detailed reports on system performance, code reviews, and post-mortem analyses for incidents.

11. Process Improvements & Technology Adoption:

- Recommend and implement enhancements to development processes, such as CI/CD pipelines (e.g., Jenkins, GitHub Actions) and containerization (Docker/Kubernetes).
- Stay abreast of advancements in Node.js (e.g., ESM modules, async/await),



React.js (e.g., Hooks, Server-Side Rendering), and database technologies (e.g., NoSQL vs. SQL trade-offs).

12. Platform Collaboration & Deployment:

- Collaborate on Node.js-supported platforms, integrating with third-party services (e.g., payment gateways, email APIs).
- Manage deployments on hosting environments like Zoho Catalyst, AWS (EC2, Lambda, ECS), ensuring auto-scaling, load balancing, and zero-downtime releases.

13. Code Management & Version Control:

- Maintain backups, version control, and code repositories using GitHub, including branching strategies (Git Flow), pull requests, and code reviews.
- Implement hooks for automated testing and deployment integration.

Working Hours & Schedule

- Working Hours: 9:30 AM to 6:30 PM IST.
- Working Days: Monday to Friday (full day); Second and Fourth Saturdays (half day).
- In cases of critical deliveries or deadlines, weekends may be required, with compensatory offs provided.
