Making the Metals Powering the World

Solcoa is building the next generation of American metalmaking, starting with rare earths — the metals of power and motion. We've developed a new chemistry that converts rare earth oxides into high-purity metals — the materials inside every EV, fighter jet, wind turbine, and data center — cleaner, cheaper, and faster than any conventional process. Now we're scaling it to thousands of tonnes of annual production.

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.

What You’ll Do

Architect, model, and draw reactor subsystems (thermal, vacuum, materials handling) in CAD (Fusion).

Specify components, tolerances, and materials for high-temperature, corrosive, and vacuum environments.

Build and iterate prototypes; run experiments; analyze data to drive design decisions.

Author procedures, test plans, and safety/operating documentation.

Collaborate with fabrication partners; support continuous improvement.

What You Bring

Required

Proficiency in CAD (Fusion)

Hands-on experience with metal machining and shop tools

Experience with high-temperature systems and/or vacuum hardware

Detail-orientation and precise technical execution

Comfort working independently in a fast-paced, build-measure-learn environment

Availability to start soon

Preferred

Coursework or experience in chemistry or physics (thermo, materials, reaction engineering, or similar)

Compensation & Benefits

Competitive base salary

Generous stock options

Comprehensive health, dental, and vision insurance

Company-provided lunch daily.

Visa sponsorship available if needed
