Thermal Systems Engineer

What You Will Do Johnson Controls is seeking a Thermal Data Center Systems Engineer! This is an entry-level position within the Data Center Thermal Solutions Engineering team. You will provide foundational experience in thermal system design, analysis, and testing for data center cooling applications. You will support product development efforts across the thermal chain—from server-level heat capture through ambient heat rejection—while developing expertise in heat transfer, fluid dynamics, thermodynamics, and integrated system design. This position is based onsite, minimum 3 days per week, at our Advanced Technology and Innovation Center located in New Freedom, PA. Candidates must be commuting distance to the facility or able to relocate.

How You Will Do It Assist with prototype development, testing, and validation of thermal components and subsystems

Participate in design reviews and contribute to thermal calculations and documentation

Learn and apply thermal modeling tools, CFD software, and test equipment under guidance

Develop understanding of the complete thermal chain from chip-level cooling to ambient heat rejection

Support cross-functional teams including controls, electrical, and mechanical engineering

What you will need

Required Bachelor of Science in Mechanical Engineering or a related field

Heat transfer analysis (conduction, convection, two-phase)

Thermodynamic cycle analysis

Fluid mechanics and hydraulic system design

Thermal system component sizing and selection

CAD proficiency

Engineering calculations and documentation

Preferred Entry level; internship or co-op experience preferred
