Rah Jobs (NOW HIRING)

Location: Glendale, KY
Employment Type: Full-Time
Work Arrangement: Onsite
Compensation: Up to $120,000/year

We are seeking a highly skilled Senior Mechanical Engineer with strong experience in industrial HVAC systems, thermal management, and environmental control. This role will serve as a technical subject matter expert for critical HVAC assets supporting advanced manufacturing environments, including dry rooms and clean rooms.

The ideal candidate will have hands-on experience with desiccant dehumidification, air handling systems, low-dew-point environments, HVAC optimization, commissioning, troubleshooting, and system performance analysis. This position will work closely with engineering, manufacturing, quality, maintenance, and external contractors to ensure reliable and energy-efficient environmental control.

• Serve as the engineering SME for industrial HVAC and environmental-control systems, including Desiccant Dehumidification Units (DHU), Recirculating Air Handlers (RAH), and Air Handling Units (AHU).
• Optimize HVAC systems for reliability, energy efficiency, humidity control, temperature stability, and overall process performance.
• Troubleshoot complex issues involving airflow, pressure cascading, humidity fluctuations, thermal loads, and environmental stability.
• Perform thermodynamic and psychrometric calculations to evaluate heating/cooling loads, moisture removal capacity, system performance, and future capacity requirements.
• Lead root cause analysis (RCA), Design of Experiments (DOE), and continuous improvement initiatives related to environmental control.
• Support HVAC retrofits, capacity expansions, equipment upgrades, and system improvement projects from design review through installation and commissioning.
• Coordinate and manage third-party contractors and HVAC vendors during engineering, installation, testing, balancing, and commissioning activities.
• Analyze HVAC and environmental performance data and collaborate with Quality and Process Engineering teams to monitor Cpk/Ppk and process capability.
• Develop predictive and preventive maintenance strategies to improve HVAC reliability and prevent environmental drift.
• Develop and maintain SOPs, preventative maintenance procedures, checklists, and critical spare-parts strategies.
• Support critical HVAC components and utilities, including desiccant systems, chilled water, steam, compressed air, valves, filtration systems, and related controls.
• Partner with cross-functional and global engineering/operations teams to resolve technical issues and implement sustainable improvements.

• Bachelor's degree or higher in Mechanical Engineering or a closely related engineering discipline.
• 5+ years of industrial HVAC engineering experience.
• Strong knowledge of industrial HVAC systems, thermodynamics, and psychrometrics.
• Experience with desiccant dehumidification and low-dew-point/low-humidity environments.
• Experience with large-scale AHU/RAH systems, airflow configuration, VFDs, filtration systems, and PID controls.
• Familiarity with industrial utility systems such as chilled water, steam, and compressed air.
• Experience with BMS, SCADA, or industrial HVAC control systems.
• Experience troubleshooting HVAC systems and performing RCA, DOE, and performance optimization.
• Experience supporting HVAC projects, contractors, commissioning, testing, and balancing (TAB).
• Proficiency with engineering and data-analysis tools such as AutoCAD/Revit, Excel, Minitab, or comparable software.
• Strong communication, project management, and cross-functional collaboration skills.

• Experience in EV battery/lithium-ion battery manufacturing.
• Experience in semiconductor, pharmaceutical, clean-room, dry-room, or other highly controlled manufacturing environments.
• Experience operating or optimizing environments requiring ultra-low humidity or very low dew points.
• Knowledge of HEPA/ULPA filtration and pressure cascade systems.
• Experience with HVAC load calculation and simulation software.
• Experience monitoring and improving environmental Cpk/Ppk performance.
• Experience managing HVAC contractors and vendors in large-scale manufacturing or construction environments.

• Regular, predictable onsite attendance is an essential function of the position.
• Ability to move throughout office, manufacturing, and construction environments, including walking, standing, bending, kneeling, and climbing stairs or ladders.
• Ability to lift and carry materials weighing approximately 25–50 pounds, with occasional heavier lifting as required, with or without reasonable accommodation.
• Ability to work in office, industrial, manufacturing, and construction environments.
• Willingness to travel to other company or project sites as business needs require.
• Reasonable accommodations may be provided to enable individuals with disabilities to perform essential job functions in accordance with applicable law.

This is an opportunity to play a key engineering role in a high-tech advanced manufacturing environment, taking ownership of critical HVAC and environmental-control systems while contributing to operational reliability, energy efficiency, and future manufacturing growth.
