2. Firmware, Field Integration & Data Acquisition

Hands-on experience working with Enode firmware or similar data loggers. Ability to integrate sensors, Modbus-based devices, and field equipment onto Enode or in-house Modbus slave frameworks. Experience validating the end-to-end data chain: o Sensor ? Modbus/RTU/TCP ? Enode ? MQTT Broker ? Raw Data Streams ? Merlin UI. Ability to troubleshoot mismatches in data registers, communication issues, and mapping errors before handover.

3. Electrical & Power System Fundamentals

Understanding of Active Power, Reactive Power, Power Factor, Apparent Power, Voltage/Current fundamentals, etc. Awareness of grid-side concepts such as inverter behavior, V/Q/PF modes, and basic protection concepts.

4. Modbus & Industrial Communication

Strong understanding of Modbus RTU/TCP protocols. Ability to work with:
Register types: Holding, Input, Coils, Discrete.

Data types: Signed, Unsigned, Float/FP32, Swapped FP, Long/Short etc.

Multipliers, byte/word order, and scaling logic.

Familiarity with OPC-UA, MQTT, TCP/IP networking is a strong bonus.

5. Technical & Analytical Skills
