About this role
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.
COMPENSATION & BENEFITS
- Competitive compensation.
- Comprehensive medical, dental and vision insurance.
- Company-provided lunch daily.
- J1 Visa sponsorship available if needed.

About this listing
Published on Ashby under the board identifier Solcoa, which is the name the employer’s own job board carries. RoleSprint has not verified the company’s registered or trading name, so it is shown exactly as published rather than tidied up.
RoleSprint is not the employer and not a recruiter. Applications are made on the employer’s own site and never reach us; what RoleSprint does is help you decide whether a role is worth your time and prepare for it if it is.
Published 5 July 2026, last checked 3 days ago. A posting stops being advertised here 90 days after the employer published it, and one the employer takes down is marked closed rather than quietly removed.
