Mechanical Engineer

Solcoa Industries is an American rare earth metals producer headquartered in Alameda, California.

We convert rare-earth oxides and magnet manufacturing scrap into the high-purity metals and alloys at the foundation of electrification, automation, and defense — the materials inside every fighter jet, EV, wind turbine, and phone.

For decades, the West has depended on China to produce these materials. Solcoa is rebuilding that supply chain at home: we're one of the very few producers outside China, and the only one developing new chemistries and a proprietary process to produce these metals at lower cost than conventional routes — without the harmful emissions.

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.

• 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.

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)

• Competitive base salary'

• Generous stock options

• Comprehensive health, dental, and vision insurance

• Company-provided lunch daily.

• Visa sponsorship available if needed
