• Select appropriate edge, cloud, and data technologies based on use cases.

Device & Edge Development

• Develop and integrate IoT device software and edge applications.
• Work with industrial protocols such as Modbus, OPC-UA, CAN, BLE, Zigbee.
• Implement offline-first and store-and-forward mechanisms at the edge.
• Perform device provisioning, configuration, and firmware updates (OTA).

Cloud & Backend Development

• Build scalable IoT backends using Azure IoT Hub / AWS IoT Core / GCP IoT.
• Design and develop APIs (REST, WebSockets) for device and application integration.
• Implement data processing pipelines (real-time and batch).
• Integrate IoT data with MES, ERP, CMMS, and analytics platforms.

Data Management & Analytics

• Structure and manage high-volume time-series data.
• Integrate sensor data into dashboards and visualization tools.
• Support AI/ML use cases such as predictive maintenance, quality monitoring.

Security & Compliance

• Implement device identity, authentication, and authorization.
• Ensure data security through encryption (at rest and in transit).
• Follow best practices for IoT security, patching, and compliance.

DevOps & Operations

• Deploy and manage IoT services using Docker, Kubernetes, CI/CD pipelines.
• Monitor system health, device connectivity, and performance metrics.
• Troubleshoot production issues across device, network, and cloud layers.

Collaboration & Documentation

• Work closely with hardware, firmware, cloud, and UI teams.
• Prepare technical design documents, architecture diagrams, and SOPs.
• Mentor junior engineers and contribute to best practices.
