As a Facilities Operations Technician III – Mechanical, you will independently support the reliability, efficiency, and lifecycle performance of mission-critical mechanical and HVAC systems within hyperscale data centers. In this role, you will apply strong technical knowledge of cooling infrastructure, mechanical plant systems, controls, redundancy strategies, and operational risk to maintain uptime and long-term system performance.
Eligibility and Location Requirements
This position requires U.S. citizenship and is located onsite in Saline, Michigan. Relocation assistance may be available in accordance with Oracle's relocation policies.
Key Responsibilities
· Independently support, inspect, maintain, and troubleshoot mechanical and HVAC systems, including chilled water, DX, airside systems, CRAH/CRAC units, pumps, valves, cooling towers, heat exchangers, and related distribution systems.
· Perform advanced troubleshooting, incident investigations, alarm response, and root cause analysis for mechanical and HVAC equipment or system issues.
· Support and improve mechanical system operation, maintenance procedures, sequences of operation, P&IDs, documentation quality, and operational standards.
· Support capacity planning, retrofits, equipment change-outs, commissioning activities, acceptance testing, and operational handover requirements.
· Partner with site operations teams to improve maintainability, safe execution of work, reliability, efficiency, and lifecycle outcomes for mechanical systems.
· Coordinate with vendors, service providers, internal engineering teams, and operations stakeholders to support maintenance, repair, testing, and system improvements.
· Use BMS, controls platforms, alarms, trends, and maintenance data to evaluate system performance, identify recurring issues, and recommend corrective actions.
· Review mechanical documentation, maintenance records, drawings, P&IDs, sequences of operation, and vendor materials to support consistent execution across sites.
· Provide field guidance and informal mentoring to less experienced technicians during inspections, maintenance, troubleshooting, and vendor-supported activities.
· Promote safe execution, environmental compliance, refrigerant-handling awareness where applicable, and continuous improvement across mechanical operations.
· Experience with mission-critical, industrial, pharmaceutical, semiconductor, healthcare, data center, or large commercial mechanical systems.
· Strong ability to interpret mechanical drawings, P&IDs, sequences of operation, equipment documentation, maintenance procedures, and vendor manuals.
· Working knowledge of chilled water systems, DX cooling, airside systems, controls integration, redundancy concepts, operational risk, and mechanical system performance.
· Demonstrated ability to independently troubleshoot mechanical and HVAC systems and communicate technical findings, risks, and recommended actions.
· Technical certification, HVAC trade experience, mechanical trade experience, apprenticeship completion, military technical training, or equivalent practical experience preferred.
· Data center or high-availability facility experience preferred but not required for candidates with strong mechanical systems experience.
· Strong mechanical and HVAC troubleshooting and diagnostic capability.
· Sound operational judgment during alarms, abnormal conditions, maintenance activities, and high-risk operating scenarios.
· Strong ownership and accountability in day-to-day mechanical operations.
· Clear communication of technical issues, findings, corrective actions, and operational risks.
· Strong safety mindset and disciplined execution of procedures, lockout/tagout, and safe work practices.
· Ability to evaluate system trends, alarm history, and maintenance records to identify improvement opportunities.
· Ability to support and mentor developing technicians in mechanical system operation, troubleshooting, and documentation practices.
· Strong coordination skills when working with vendors, site operations, engineering teams, and service providers.
Preferred Skills / Certifications
· Experience with chillers, pumps, cooling towers, CRAH/CRAC units, heat exchangers, water treatment interfaces, valves, mechanical distribution systems, and airside cooling equipment.
· Familiarity with BMS, PLC/controls concepts, sequences of operation, trending, alarm management, commissioning, and vendor coordination.
· Experience supporting maintenance planning, acceptance testing, energy-efficiency projects, equipment change-outs, and operational handover.
· EPA Section 608 Technician Certification preferred for roles involving refrigerant-handling activities on stationary HVACR equipment.
