What you'll do

• Lead reliability initiatives for critical mechanical systems including chilled water infrastructure, CRAH/CRAC systems, and cooling towers.
• Review commissioning and startup quality to ensure mechanical systems are delivered in a supportable condition.
• Design and improve maintenance strategies to reduce downtime and optimize lifecycle costs.
• Lead root cause analysis and develop corrective actions for major or recurring mechanical failures.
• Analyze maintenance data and operating trends to identify systemic issues and prioritize improvements.
• Develop risk mitigation plans for cooling system vulnerabilities, latent failure points, and obsolescence.
• Provide senior technical support during critical mechanical events and abnormal operating conditions.
• Evaluate construction submittals and design changes from a reliability and maintainability perspective.

What we're looking for

• 6 to 10+ years of experience in critical cooling, HVAC, mechanical reliability, commissioning, or uptime-critical infrastructure environments.
• Bachelor’s degree in Mechanical Engineering or a related field is preferred.
• Deep familiarity with cooling system arrangements, component failures, automation interfaces, and large system effects.
• Experience leading root cause analyses (RCAs), maintenance optimization, and technical support in live mechanical plant environments.
• Ability to analyze maintenance data, operating trends, and failure patterns to identify systemic issues.
• Strong systems thinking and technical judgment for mechanical infrastructure.
• ASHRAE credentials, HVAC certifications, or other reliability certifications like CMRP or CRE are a plus.
• Must be able to read, write, and speak English.
