Cooling performance limits high-power computing, semiconductor fab, cell networks, photonics, power electronics, and most of our digital world. JCI enables customers to overcome these constraints with novel, complex metal components that dramatically improve heat dissipation in high-performance systems. JCI’s patented Stack Forging™ process enables complex micro-geometries, resulting in single-piece, leak-tight parts that deliver superior cooling performance, lower pressure drops, and exceptional reliability.

This role generally requires 4 days onsite per week.

What you’ll do:

As a Simulation Engineer you will use hand calculations and computational tools to predict the performance of JCI's industry-leading thermal management components. You will work closely with JCI’s Solutions Engineers and Thermal Design Engineers on optimizing designs to meet challenging customer requirements. You will have the opportunity to help develop our simulation best practices and learn from our current simulation experts.

This role generally requires 4 days onsite per week.

Responsibilities:

**Responsibilities are subject to change based on shifting business needs

• Do 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

Qualifications:

• Bachelors in Mechanical Engineering, Aerospace Engineering, or other relevant field

• 2–5 years of industry experience

• Experience with Siemens Sim Center or similar (required)

• 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
