Thermal-Fluids Simulation Engineer

About the role

Alloy Enterprises enables customers to overcome cooling performance limits in high-power computing, semiconductor fabrication, cellular networks, photonics, power electronics, and other digital infrastructure with novel, complex metal components that dramatically improve heat dissipation. Alloy’s patented Stack Forging™ process produces single-piece, leak-tight parts with complex micro-geometries, delivering 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.

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

Responsibilities are subject to change based on shifting business needs.

Qualifications

• Bachelor’s 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 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, providing thermal performance estimates within a few days to accelerate customer-facing projects
• Familiarity with design engineering work and an understanding of the engineering design process
