Ideal candidates are local to the New Freedom, Pennsylvania site or willing to travel frequently to work alongside design engineering teams and test labs. Domestic and international travel of up to 15% is required.

Requirements

Bachelor's degree in Mechanical Engineering, Electrical Engineering, or a related engineering discipline, or equivalent relevant technical experience.
At least 7 years of experience with commercial HVAC/R equipment, preferably large-tonnage applied equipment or water-cooled centrifugal chillers.
Demonstrated ability to troubleshoot and resolve complex system-level technical problems.
Strong understanding of the refrigeration cycle and its application to water-cooled centrifugal chillers.
Experience interpreting chiller operating data, trends, control information, performance data, and field observations to identify root cause.
Ability to develop technical test plans and use engineering data to validate solutions and product changes.
Strong written and verbal communication skills, including the ability to explain complex technical information to engineering, service, sales, and customer audiences.
Ability to travel domestically and internationally up to 15%.

Nice To Haves

Extensive hands-on experience with magnetic-bearing centrifugal chillers.
Understanding of active magnetic bearings, permanent-magnet motors, magnetic-bearing controllers, variable-speed drives, and chiller controls.
Experience troubleshooting compressor operating-map, surge, driveline, controls, vibration, electrical, or system-application issues.
Experience supporting complex field escalations and conducting formal root-cause investigations.
Experience with new-product-development processes, DFMEA and design reviews, engineering validation testing, and product launch activities.
Experience authoring technical service literature, troubleshooting procedures, training material, or technical bulletins.
Demonstrated ability to mentor engineers and service professionals and build technical capability across an organization.

Responsibilities

Serve as the subject matter expert for YORK magnetic-bearing water-cooled centrifugal chillers and provide technical leadership across the product lifecycle.
Provide advanced technical support to global Field Sales, Service, and Product Technical Support through site visits, remote troubleshooting, technical reviews, and escalation support.
Lead diagnosis and resolution of complex problems involving refrigeration, compressors, magnetic-bearing systems, motors, variable-speed drives, controls, heat exchangers, applications, and unit performance.
