Jobs in York, PA

About the role

Johnson Controls’ Data Center Thermal Technology Solutions group is seeking a Senior Modeling Engineer. As a member of the modeling team, you will develop and apply numerical models to simulate the end-to-end performance of data center cooling systems. You will play a key role on cross-functional teams responsible for creating comprehensive thermal solutions for data center applications.

What you'll bring

• Master’s or PhD in Mechanical Engineering or a related field.
• 3+ years of industry experience with thermal products or systems.
• Strong theoretical foundation in thermodynamics, heat transfer, and fluid mechanics.
• Experience with HVAC system design, refrigerant cycles, and component selection.
• Proficiency with numerical simulation tools for building and thermal applications (e.g., Modelica, MATLAB/Simulink, EES, EnergyPlus).
• Broad cross-domain knowledge spanning thermal, controls, and electrical systems—generalists with strong multidomain capability are highly valued.
• Proficiency with Microsoft 365/Excel, including basic macros/VBA for data analysis and reporting.
• Demonstrated ability to execute cross-functional projects.
• Python scripting and environment management (package installation, virtual environments, basic automation).
• Fundamentals of controls engineering (feedback loops, PID tuning, system response).
• Basic understanding of electrical systems (motor sizing, VFDs, power distribution).
• Experience with refrigeration system design and refrigerant properties.
