Cooling performance limits high-power computing, semi-conductor fab, cell networks, photonics, power electronics, and most of our digital world. Alloy Enterprises enables customers to break through 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 45-person hardtech startup that has raised over $50M in capital and is shipping components to customers manufacturing servers, lasers, semiconductor equipment, and defense systems.
About The Role
We are looking for a hands-on Mechanical or Industrial Engineering Co-op to support our thermal test lab and product validation efforts. This role is ideal for someone who enjoys building, troubleshooting, and working directly with hardware.
