Metallurgical Engineering Intern

Alameda, CaliforniaFull-timePosted Jul 5, 2026

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 Join our process team and help convert rare-earth oxides into high-purity metals. You’ll support reactor operations, run experiments and characterize feed materials and products, working with metallurgists, chemists and technicians to move from lab-scale experiments to repeatable production.

WHAT YOU’LL DO

Assist with high-temperature and high-vacuum reactor operations.
Help characterize feed materials and products using ICP-OES, SEM-EDS, LECO O/N.
Run furnace cycles, collect process data, and summarize results to inform design iterations.
Maintain organized logs of process parameters, equipment conditions, and sample tracking.
Support equipment maintenance: vacuum systems, induction coils, thermocouples, and gas handling.
Contribute to safety-first culture and continuous improvement on the facility floor. WHAT YOU BRING REQUIRED
Pursuing a BS/MS in Metallurgical Engineering, Materials Science, or related field.
Exposure to pyrometallurgy, electrometallurgy, or high-temperature processing (coursework or labs).
Hands-on experience from labs, foundry work, internships, or personal projects (furnaces, casting, heat treatment).
Detail-oriented, disciplined documentation, and reliable follow-through.
Comfortable in a fast-paced, hardware-centric environment and willing to get your hands dirty.
On-site availability; able to start soon. PREFERRED
Experience with vacuum or inert-atmosphere furnace operation.
Familiarity with rare-earth metallurgy, molten salt electrolysis, or reactive metal processing.
Basic thermodynamic analysis skills (Ellingham diagrams, phase diagrams, FactSage/HSC a plus).
Welding or basic machining experience (mill/lathe).
Python/MATLAB for data analysis.
