At Johnson Controls, we don’t work around those limits—we eliminate them. Powered by our breakthrough Stack Forging™ process, we engineer high-performance thermal components and integrated cooling loop solutions designed for direct deployment into AI, HPC, and other demanding environments. The result: a best-in-class thermal management platform built for the systems that push performance to the edge—and beyond. In this role, you won’t just model performance—you’ll help redefine what’s possible. Leveraging both first-principles analysis and advanced computational tools, you’ll predict and push the limits of JCI’s cutting-edge thermal management technologies.You’ll collaborate closely with Solutions Engineers and Thermal Design Engineers to solve complex, high-stakes challenges and optimize designs that meet—and exceed—demanding customer requirements. Along the way, you’ll play a key role in shaping our simulation best practices, influenci
