# Research Engineer - Company: [Solcoa]() - Location: Alameda, California - Team: Engineering - Employment type: Full Time - Salary: $120K – $175K - Posted: September 2, 2025 ## Job description ## 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 ## Apply [Apply on Solcoa]() Canonical job page:
