Principal Condition Monitoring Engineer - Power Generation - Data Center Infrastructure (on-site Nashville, TN)

This engineer combines field inspections, online monitoring, diagnostic testing, and operating-data analysis to detect deterioration, assess equipment health, and recommend timely maintenance. The role partners with operations, maintenance, electrical, mechanical, controls, reliability, and equipment manufacturers to support safe operation and prevent unplanned outages., * Develop and manage condition monitoring programs, asset criticality assessments, inspection routes, monitoring frequencies, baseline measurements, return-to-service activities by establishing baselines and identifying equipment health indicators abnormal equipment behavior for generation and utility substation assets.

• Perform vibration analysis using spectra, time waveforms, phase, envelope analysis, and operating trends to identify imbalance, misalignment, looseness, bearing defects, and other rotating-equipment faults.
• Lead condition monitoring programs for power generation and utility substation assets, establish monitoring priorities, baselines, alarm thresholds, and escalation criteria.
• Monitor gas turbines, diesel and natural-gas reciprocating generators, alternators, and auxiliary equipment using vibration analysis, thermography, lubricant analysis, ultrasound, and operating trends to identify deterioration and developing faults.
• Assess utility substation equipment, including transformers, bushings, circuit breakers, switchgear, and cables, using thermal surveys, oil and dissolved gas analysis, and applicable electrical diagnostic results.
• Interpret transformers dissolved gas analysis, oil quality, moisture, temperature, cooling-system performance, and bushing and tap-changer condition; correlate trends with loading, operating history, and laboratory findings.
• Conduct infrared thermography and ultrasound surveys; assess partial-discharge data where applicable, breaker operating times and contact resistance, insulating-medium condition, and insulation test results with electrical testing specialists.
• Establish and periodically review condition baselines, alarm thresholds, diagnostic rules, and escalation criteria using manufacturer guidance, operating context, equipment history, and applicable standards; coordinate changes through approved controls.
• Analyze alarms and abnormal trends, confirm data validity, assess fault severity and progression, and issue actionable recommendations with urgency, operating implications, inspection needs, and maintenance priorities.
• Translate findings into maintenance work orders, outage scopes, repair and replacement recommendations, and asset-life assessments; track actions to closure and confirm equipment condition after maintenance.
• Support commissioning, acceptance testing, startup and shutdown monitoring, load testing, and return-to-service activities by establishing baselines and identifying abnormal equipment behavior.
• Maintain diagnostic reports, asset health dashboards, inspection records, and computerized maintenance management system data; report defect detection, monitoring coverage, action closure, and reliability improvement, and train site personnel.

The Condition Monitoring Engineer role requires 6-10+ years of relevant experience in power plant monitoring, including gas turbines, reciprocating generators, diesel and natural-gas generation, associated alternators, and balance-of-plant systems.
