Test Technician


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


The Test Technician is responsible for the controlled assembly and verification of liquid cooling hardware, including cooling plates and fully integrated cooling loops. This role supports production by ensuring assemblies are built in accordance with released work instructions and validated through standardized test methods for leakage, flow performance, pressure drop, and thermal behavior. This work supports both low-volume development efforts and higher-volume production programs.


Work is performed within an ISO 9001-compliant and ITAR-controlled manufacturing environment.


This role requires 5 days onsite per week.
