Senior Thermal Simulation Engineer (onsite)
About The Position
Thermal limits are the hidden bottleneck holding back the world’s most advanced technologies—AI infrastructure, semiconductor equipment, power electronics, and mission-critical defense systems. 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, influencing how we scale excellence, and continuing to learn alongside some of the industry’s top simulation talent.
Requirements
- Bachelors in Mechanical Engineering, Aerospace Engineering, or other relevant field
- Experience with CFD simulation software
- 7+ years of experience in thermal-fluid simulation and analysis, including but not limited to comfort with selecting turbulence closures, running mesh refinement studies, estimating model error, and extracting dimensionless correlation coefficients from simulations
- Experience with a wide range of reference literature on calculating thermal and fluid behavior of components
- Ability to deliver results in a quickly evolving environment, delivering estimates for thermal performance of a design within a few days to accelerate customer-facing projects
- Familiarity with design engineering work, specifically, an understanding of what an engineering design process looks like and how their work informs that process
Responsibilities
- Hand calculations, select appropriate correlation coefficients, and build simple scaling models
- Perform coupled thermo-fluid simulations using CFD software to predict pressure drop and thermal performance
- Provide guidance and input on customer development projects
- Develop and improve best practices around simulation
Benefits
- competitive Bonus plan that will take into account individual, group, and corporate performance
- competitive benefits package
