What You Will Do Johnson Controls’ Data Center Thermal Technology Solutions group is seeking a Research and Advanced Development 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. Your primary focus will be simulating system performance and providing design and application guidance based on model results. As part of the advanced development team, you will also stay current on emerging technologies in the data center cooling space and evaluate innovations that may influence future product offerings.

The Modeling Engineer is based on-site at the Warren Johnson Engineering Lab in Glendale, WI, with a minimum requirement of three days per week on-site. Other locations that will be considered are New Freedom, PA, Boston, MA, or remote for the right person. Various relocation packages are available.

How You Will Do It

Develop numerical simulations of thermal components commonly used in data center applications.
Integrate subsystems into complete thermal solutions, coordinating 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 write white papers communicating JCI’s technical perspective on emerging technologies and system architectures.
Actively participate in industry groups such as ASHRAE and the Open Compute Project.

What You Will Need Required

Bachelor's, Master’s or PhD in Mechanical Engineering or a related field.
7+ 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).
Demonstrated ability to execute cross-functional projects.

Preferred

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.
Familiarity with data center cooling architectures (direct liquid cooling, rear-door heat exchangers, CDUs).
Expertise in one or more thermal domains (CDUs, chillers, dry coolers, cold‑plate systems).
Broad cross-domain knowledge spanning thermal, controls, and electrical systems - generalists with strong multidomain capability.

SALARY RANGE: $100,000 - $140,000 (Salary to be determined by the education, experience, knowledge, skills, and abilities of the applicant, internal equity, and alignment with market data.) This role offers a competitive Bonus plan that will take into account individual, group, and corporate performance. This position includes a competitive benefits package. The posted salary range reflects the target compensation for this role. However, we recognize that exceptional candidates may bring unique skills and experiences that exceed the typical profile. If you believe your background warrants consideration beyond the stated range, we encourage you to apply. To support an efficient and fair hiring process, we may use technology assisted tools, including artificial intelligence (AI), to help identify and evaluate candidates. All hiring decisions are ultimately made by human reviewers. For details, please visit the About Us tab on the Johnson Controls Careers site at https://jobs.johnsoncontrols.com/about-us
