What is a thermal fluid simulation engineer?

A Thermal Fluid Simulation Engineer is a specialized engineer who uses computational tools and modeling techniques to analyze and predict the behavior of fluids and heat transfer in various systems. These engineers work on projects involving heating, cooling, and fluid flow, often in industries like automotive, aerospace, energy, or manufacturing. Their work helps optimize designs for efficiency, safety, and performance by simulating real-world thermal and fluid dynamics before prototypes are built. They typically use software like ANSYS Fluent or COMSOL Multiphysics and collaborate closely with other engineering teams.

What are the key skills and qualifications needed to thrive as a thermal fluid simulation engineer?

To thrive as a Thermal Fluid Simulation Engineer, you need a solid background in mechanical or chemical engineering, thermodynamics, and fluid mechanics, typically supported by a relevant engineering degree. Proficiency with simulation tools such as ANSYS Fluent, COMSOL Multiphysics, or MATLAB, as well as experience in computational fluid dynamics (CFD), is essential. Strong analytical thinking, problem-solving, and effective communication skills help you interpret data and present findings clearly to multidisciplinary teams. These skills and qualifications are crucial for accurately modeling complex thermal-fluid systems and delivering reliable solutions in engineering projects.

What are some common challenges faced by thermal fluid simulation engineers when validating simulation results with real-world data?

Thermal Fluid Simulation Engineers often encounter challenges when correlating simulation data with real-world results due to factors such as incomplete material properties, uncertainties in boundary conditions, and complexities in physical phenomena like turbulence or phase changes. Accurately modeling these factors requires close collaboration with experimental engineers and access to high-quality experimental data. To address these challenges, engineers frequently calibrate models, apply sensitivity analyses, and iteratively refine their simulations to improve agreement with test results, ensuring reliable and actionable insights for design or process optimization.

Job description

Cooling performance limits high-power computing, semiconductor fab, cell networks, photonics, power electronics, and most of our digital world. Alloy Enterprises enables customers to overcome these constraints with novel, complex metal components that dramatically improve heat dissipation in high-performance systems. Alloy'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. Founded in 2020, Alloy is a 50-person hardtech startup that has raised over $40M in capital and is shipping components to customers manufacturing AI servers, lasers, semiconductor equipment, and defense systems.
This role generally requires 4 days onsite per week.
What you'll do:
As a Thermal-Fluids Simulation Engineer you will use hand calculations and computational tools to predict the performance of Alloy's industry-leading thermal management components. You will work closely with Alloy'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+ years of industry experience
  • Experience with Siemens SimCenter (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, 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

*Pay Range: $85,000-105,000 annually dependent on experience, qualifications, and education level
