Making the Metals Powering the World. Solcoa exists to stabilize the western rare-earth metal supply chain—powering every fighter jet, EV, wind turbine, phone, and generator. We’re among the very few companies outside China producing rare-earth metals—and the only one delivering a 100% U.S. supply of both light and heavy rare earths. Our carbon-zero process converts end-of-life magnets directly into metal, accelerating energy independence and securing one of the world’s most vital resources.
We are a lean, well-funded team rapidly accelerating Western rare-earth production. We’re building a world-class team to solve this crisis.
The Role — Research Engineer
Own difficult, first-principles R&D that unlocks rare-earth metal production at scale. You will design and execute high-temperature experiments, build and operate custom rigs, extract mechanisms from data, and translate lab breakthroughs into reproducible unit operations for our demo plant. This role is deeply technical and experimental.
- Pyrometallurgical research : calcination, vacuum / steam distillation, carbothermic / metallothermic reduction, smelting, refining.
- High-temperature electrochemistry : molten-salt / molten-oxide electrolysis, cell design, anode / cathode materials, current efficiency.
- Nuclear engineering research : molten-salt chemistries, materials compatibility, graphite / refractory behavior, high-T gas-cooled systems.
- Metal processing engineering : molten metal handling / casting, powder metallurgy (atomization, pressing, sintering), heat treatment.
What You’ll Do
Run bench / pilot experiments to quantify kinetics, transport, and equilibria.Build / operate furnace systems, vacuum / inert atmospheres, retorts / crucibles.Develop and validate PFD-level experimental flows; compute mass / energy balances; establish operating envelopes.Apply thermochemical modeling (CALPHAD / Thermo-Calc / FactSage / HSC) and phase diagrams to guide conditions and materials.Characterize feed / products with ICP-MS / OES, XRD, SEM / EDS, LECO O / N / H; close element balances.Author rigorous documentation : SOPs, test plans, hazards analyses, data packages; present results with statistical confidence.Collaborate with machinists / technicians to fabricate fixtures; specify sensors, heaters, seals, and vacuum hardware.Enforce safety for molten metals, reactive powders, hot work, compressed gases, and magnetized materials.What You Bring
Required
Typically 3+ years (flexible) as a research engineer / assistant or PhD-level researcher with demonstrated research achievements (papers, patents, prototypes).Depth in at least one focus area above; strong foundation in thermodynamics, transport, reaction kinetics, and materials.Proven ability to build experimental setups, write / control test scripts, and produce decision-grade data.Hands-on with furnaces, vacuum / inert gas systems, gloveboxes, and high-T instrumentation; meticulous lab discipline.Data fluency (Python / MATLAB, spreadsheets); uncertainty analysis; clear, technical writing.Preferred
Experience with rare-earth chemistry / metallurgy (Nd, Dy, Tb), chloride / fluoride molten salts, and contamination control.Corrosion / materials compatibility at high temperature; selection of refractories and crucible / alloy systems.Basic CAD (Fusion / SolidWorks) for fixtures; simple FEA / thermal modeling; familiarity with HAZOP / MOC culture.Compensation & Benefits
