About this role

Making the Metals Powering the World

Solcoa exists to stabilize the western rare-earth metal supply chain—powering every fighter jet, EV, wind turbine, phone, and generator. We’re among the very few companies outside China producing rare-earth metals—and the only one delivering a 100% U.S. supply of both light and heavy rare earths. Our carbon-zero process converts end-of-life magnets directly into metal, ready to accelerate energy independence and secure one of the world’s most vital resources.

We are a lean, well-funded team rapidly accelerating Western rare-earth production. We’re building a world-class team of engineers to solve this crisis.

The Role — Mechanical Engineer

We’re looking for a hands-on mechanical engineer to design, prototype, and scale the next generation of our rare-earth reactors. You’ll own designs from concept through commissioning, working closely with machinists and researchers to turn ideas into operating systems.
