Implement and optimize industrial communication protocols (Modbus, MQTT, Ethernet/IP)

Build real-time data pipelines for telemetry and sensor data ingestion on-premise

Develop device provisioning, management, and over-the-air (OTA) update capabilities

Create and maintain local IoT platform components with no cloud dependency

Write clean, testable, and well-documented code following best practices

Collaborate with firmware, hardware, and QA teams to ensure seamless system integration

Optimize system performance, reliability, and scalability within local infrastructure

Implement security best practices for device-to-server communication on isolated networks

Participate in code reviews and contribute to architectural decisions
