Full Stack Developer (MERN Stack)

Full Stack Developer will play a key role in building and enhancing a scalable, use-case-agnostic IoT cloud platform that integrates data from diverse devices and external systems. This role involves development across the entire application stack—from Node.js-based backend services and APIs to React-based front-end interfaces—ensuring seamless data flow, intuitive user experiences, and reliable platform operations.

The developer will work closely with cross-functional teams to deliver high-quality, maintainable code, leveraging Azure cloud services and modern engineering practices. As part of an AI-native team, the developer is expected to actively use AI tools for accelerated development, problem solving, documentation, and continuous learning. A passion for experimentation, adaptability, and skill growth is essential to thrive in this role.

Code Quality, Review & Collaboration

• Participate in peer code reviews with focus on maintainability, performance, and secure coding.
• Contribute to evolving coding guidelines, reusable libraries, and platform-wide shared components.
• Maintain clear API documentation (Swagger/OpenAPI), inline comments, and READMEs.
• Collaborate cross-functionally with QA, DevOps, Data, and Device Integration teams.

Testing & Validation

• Write unit, integration, and end-to-end tests using standardized testing frameworks.
• Validate UI behavior, performance, accessibility, and data consistency across services.
• Debug issues using logs, monitoring dashboards, and cloud troubleshooting tools.
• Ensure graceful error handling, fail-safes, retries, and robustness under varying IoT data patterns.

Deployment, CI/CD & Release Management

• Configure and maintain CI/CD pipelines for automated build, test, and deployment processes.
• Work with containerization/orchestration (Docker/K8s) where applicable.
• Follow clean Git workflows and version control best practices.
• Validate changes in non-production environments prior to rollout.

Application Monitoring & Continuous Improvement

• Monitor application health, logs, telemetry, and performance metrics.
• Troubleshoot production bugs and perform root-cause analysis (RCA).
• Reduce technical debt by refactoring and updating outdated implementations and libraries.
• Optimize API and UI performance based on real customer usage.

Continuous Learning & Team Enablement

• Stay updated with emerging cloud, IoT, JavaScript/TypeScript, and full-stack development trends.
• Participate in knowledge-sharing, internal workshops, and platform improvement initiatives.
