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 multi-unit or hybrid configurations.


* Support CFD reviews/simulations and thermals; ensure containment alignment and airflow management.

3) RCA, Quality & Continuous Improvement


* Conduct/participate in RCA investigations; define CAPA; track effectiveness to closure.


* Analyze field data and trends to identify systemic issues; drive design/firmware changes with engineering/factories.


* Contribute to reliability improvements, de-risking known failure modes and eliminating repeat incidents.

4) Technical Content, Tools & Knowledge Enablement


* Author and maintain troubleshooting guides, technical bulletins, SOO/best practices, and service playbooks for Field/L1teams and Partners.


* Deliver targeted training (classroom/virtual/field), tech talks, and workshops (e.g., PID tuning, refrigeration diagnostics, airflow/containment).


* Ensure content is accurate, discoverable, and up to date in service tools and knowledge repositories.

5) Cross-Functional & Factory Collaboration


* Partner with Engineering, R&D, Product Engineering, Global Technical Teams, and OEM factories to resolve product issues, validate firmware fixes, align field behavior to factory specifications, and support new technology introductions.


* Participate in design reviews, capacity planning inputs, and customer-facing RCA presentations for hyperscale/enterprise/colo/VIP accounts.

6) Governance, Safety & Compliance


* Enforce safety standards, lockout/tagout, refrigerant handling best practices; ensure compliance with company policies and industry standards (e.g., ASHRAE thermal guidelines, EN 378, EPA 608 or local equivalent, F-Gas/MoEFCC or local).


* Maintain rigorous documentation (service reports, commissioning records, asset baselines, parameter sets).
