Mechanical EngineerAlameda, California

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
