• Prepare technical recommendations including corrective actions, required parts, estimated labor, urgency, and supporting evidence.
• Support the commercial cycle by clarifying scope, joining customer discussions, and handing work over to operations.
• Onboard newly connected chillers, ensuring asset data, alarm setup, communication status, and monitoring readiness.
• Identify offline or poorly communicating chillers, coordinate remote troubleshooting, and arrange field interventions.
• Share weekly and monthly updates on critical alarms, aging actions, site visits, opportunities, offline assets, and recurring issues.

• Strong practical knowledge of chiller refrigeration cycles, compressors, evaporators, condensers, cooling‑water systems, pumps, valves, sensors, safeties, controls, and common failure modes.
• Ability to interpret chiller alarms, operating data, trends, controller information, service reports, wiring diagrams, and technical manuals.
• Experience diagnosing site issues, defining corrective scopes, identifying required parts, and supporting repair quotations.
