Must Have: Cooling systems experience, strong mechanical skills, and a critical systems background; CDU experience highly preferred

We are seeking an experienced Data Center Critical Mechanical Specialist to lead mechanical systems management in our data center facilities. This role is pivotal in ensuring the continuous, efficient, and safe operation of all mechanical systems, including Cooling Distribution Units (CDUs), air-cooled chillers, pumps, VFDs, cooling towers, Packaged Rooftop Units (RTUs), air handling units (AHUs), and fan walls. The ideal candidate will demonstrate deep expertise in mechanical systems — particularly CDU maintenance and operation — advanced troubleshooting skills, and a strong understanding of how to optimize the performance of critical mechanical infrastructure.

• Provide guidance and oversight of the operation and maintenance of all mechanical systems critical to the data center's functioning, including direct experience with CDU maintenance, calibration, and performance optimization.
• Ensure all mechanical systems run efficiently, minimizing downtime and meeting environmental and operational standards.
• Develop best practices and procedures for routine inspection, cleaning, troubleshooting, and preventive maintenance of CDUs to ensure consistent cooling distribution and system reliability.
• Manage and optimize cooling strategies for all data center infrastructure to maintain optimal temperature and humidity levels, ensuring uptime and system efficiency.
• Oversee monitoring of cooling infrastructure and performance, implementing improvements as necessary to meet capacity and environmental standards.
• Act as subject matter expert in diagnosing and resolving mechanical issues impacting data center operations, including HVAC malfunctions, cooling failures, and air quality problems.
• Assist in performing root cause analysis on mechanical failures and lead efforts to correct and mitigate future issues.
• Assist in the development and execution of a comprehensive preventive maintenance program for all mechanical systems to avoid unplanned outages or failures.
• Develop and implement predictive maintenance tools to monitor system health and schedule repairs or upgrades before failures occur.
• Ensure mechanical systems meet all regulatory, safety, and environmental standards including ASHRAE guidelines, local building codes, and OSHA requirements.
• Conduct regular audits and inspections of mechanical equipment to ensure safety and compliance with all regulations and company policies.
• Maintain detailed records of mechanical system performance, inspections, maintenance, repairs, and upgrades.
• Offer technical expertise and guidance in troubleshooting, system design, and operation of mechanical systems to site personnel as needed.

• Bachelor's degree in Mechanical Engineering, Facilities Management, or a related field preferred; equivalent military, trade school, or extensive hands-on experience will be considered.
• 7 years of experience in the maintenance and operation of critical mechanical systems, with a focus on data centers or mission-critical facilities, including hands-on CDU maintenance and repair.
• Demonstrated expertise in troubleshooting and resolving complex mechanical issues in high-availability environments.
• Strong understanding of energy management and efficiency practices for mechanical systems, with emphasis on CDU optimization in mission-critical environments.
• Ability to lead projects, troubleshoot complex issues, and implement long-term solutions to mechanical challenges.
• Familiarity with monitoring systems, predictive maintenance tools, building automation systems (BAS), and CDU diagnostic software.
• Ability to work in a high-pressure, mission-critical environment while maintaining focus and effectiveness under stress.
• EPA 608 Universal Certification a plus.
