Cooling Engineering Support Principal

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).
