About us

Alloy Enterprises is transforming how aluminum parts are made. Aluminum will be part of the electrification journey of everything that moves, and flexible, on-demand, and cost-competitive fabrication will be essential to this transition. Automotive, aerospace, and industrial equipment need to be lighter, and fabrication methods need to keep pace with the speed of innovative new designs. Our novel, scalable, full-stack additive manufacturing process disrupts the multi-year lead time, process limitations, and high up-front cost of aluminum casting.

“Alloy Enterprises is fundamentally transforming aluminum manufacturing for transportation, much like Carnegie Steel did for the railroad 100 years ago. Now is the time for us to bring scalable additive aluminum manufacturing to mass production and accelerate our society’s ability to electrify everything that moves.” - Alison Forsyth, CEO

Founded in early 2020, the company has raised $38M and is generating revenue with our pilot manufacturing facility. For the first time, on-demand fabrication meets the cost and scale of casting in an exploding $102B market – largely driven by electrification. We are now building out our team and production fab facilities to meet customer demand. If you are a sleeve-rolling builder who sets their bar high and enjoys thinking out loud in a collaborative and inclusive working environment, we’d love to hear from you.

We are looking for a Material Process Engineering co-op to help to develop and standardize processes for a novel feedstock material. Strong communication, flexibility, and the desire to “wear many hats'' will all be essential skills for any successful applicant. You will be expected to teach yourself new skills and apply them to complete your tasks and projects, but you will receive guidance and mentorship along the way.
