Thermal-Fluids Simulation Engineer

Alloy Enterprises • Burlington, MA

140d • $85,000 - $105,000 • Hybrid

About The Position

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.

Requirements

• 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
• Applicants must be authorized to work for any employer in the U.S. We are unable to sponsor or take over sponsorship of an employment Visa, including H-1B, H-1C, H-2A, H-2B, H-3, F-1 or OPT at this time.

Responsibilities

• 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
