Cooling Engineering Support Principal

The Cooling Principal is responsible for level 2 engineering support, and to be the technical expert on site 1) Advanced Troubleshooting & Escalations Serve as the final/near-final technical escalation point for PAC/DX/CRAC/CRAH, InRow/InRoom, chillers, pumps, and hydronics, hybrid/economizer systems, MDC cooling, Cool Array modular solutions, and high-density air/liquid cooling. Perform deep-dive diagnostics: refrigeration cycle, SOO (Sequence of Operation), controller logic, firmware anomalies, PID tuning, multi‑unit interaction, VFD/EC fan faults, BMS/communication (Modbus/BACnet/SNMP), airflow/thermal imbalance, humidity system issues, electrical/PCB. Execute remote and on‑site support; validate operating parameters; perform safe emergency interventions where required. 2) Commissioning, Recommissioning & Optimization Lead start-up and commissioning for the full APC–Uniflair portfolio (single and multi-module). Optimize parameters and control sequences; validate SOO and stability in...
