Job summary

JLL is seeking a Reliability Engineer in the Saint Louis area to lead maintenance optimization for building systems and infrastructure. You will integrate data from BAS, fault detection, and CMMS to guide repair-versus-replace decisions and deploy condition-based monitoring.

You will develop predictive maintenance strategies, perform RCA, and advance uptime while collaborating with the Engineering Services Reliability & Asset Management Center of Excellence.

Qualifications

• Bachelor's degree in Engineering (Mechanical or Electrical preferred).
• 5-10 years of experience implementing reliability-centered maintenance and condition-based monitoring methods.
• Proven experience with building automation systems and automated fault detection and diagnostics platforms.
• Extensive knowledge of mechanical, electrical, plumbing, and fire suppression systems in commercial or critical facilities.
• Demonstrated ability to use computerized maintenance management systems (CMMS) and analyze large datasets.
• Strong understanding of predictive maintenance technologies such as vibration analysis, infrared thermography, ultrasound, and oil analysis.
• Experience conducting root cause failure analysis, equipment criticality ranking, and PM/PdM optimization.
• Ability to read and interpret technical drawings, schematics, and equipment manuals.

Responsibilities

• Implement and optimize preventive and predictive maintenance programs using reliability-centered maintenance (RCM) principles and condition-based monitoring technologies.
• Analyze data from building automation systems, fault detection platforms, and CMMS to identify trends, predict failures, and improve maintenance strategies.
• Conduct root cause failure analysis on critical equipment breakdowns and develop corrective action plans that prevent recurrence.
• Rank asset criticality across the portfolio and define cost-effective proactive maintenance approaches tailored to each asset's importance.
• Perform facility condition assessments to evaluate remaining useful life of building systems and infrastructure, documenting findings for capital planning.
• Collaborate with maintenance, planning, and operations teams to ensure reliability metrics meet performance targets.
• Deploy predictive maintenance technologies including vibration analysis, thermography, ultrasound, oil analysis.
• Maintain accurate equipment records, failure histories, and maintenance plans within the CMMS.
