Remote Senior Data Center Thermal Modeling Engineer

Alloy Enterprises; York (York County); Hybrid; USD 110,000 - 140,000; Full time

Job summary

Johnson Controls is seeking a Senior Modeling Engineer for its Data Center Thermal Technology Solutions group. You will develop numerical models to simulate end-to-end performance of data center cooling systems and provide design guidance based on results.

Based in Glendale, WI or York, PA, or remote for the right candidate, you will integrate subsystems, predict chip-to-ambient performance, and present findings across departments.

Qualifications

• Master’s or PhD in Mechanical Engineering or related field.
• 3+ years of industry experience with thermal products or systems.
• Strong 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).
• Cross-domain knowledge spanning thermal, controls, and electrical systems.
• Proficiency with Microsoft 365/Excel, including basic macros/VBA for data analysis and reporting.
• Demonstrated ability to execute cross‑functional projects.

Responsibilities

• Develop numerical simulations of thermal components used in data center applications.
• Integrate subsystems into complete thermal solutions across cooling loops, controls, and heat rejection equipment.
• Use simulation tools to predict chip‑to‑ambient performance of data center cooling systems.
• Apply system‑level performance models to provide technical guidance to customers.
• Present project status, technical findings, and strategic recommendations across departments.
• Deliver presentations and/or white papers communicating Johnson Controls’ technical perspective on emerging technologies and system architectures.
• Actively participate in industry groups such as ASHRAE and the Open Compute Project.
