Research Engineer

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 - Competitive base salary - Comprehensive health, dental, and vision insurance - Company-provided lunch daily - Visa sponsorship available if needed
