About the Role
Solcoa is building the next generation of American metalmaking, starting with rare earths. The Staff Mechanical Engineer will own the mechanical and thermal design of high-temperature reactors, focusing on simplification, manufacturability, assembly, and maintenance.
Responsibilities
- Own the mechanical and thermal design of Solcoa’s modular high-temperature reactors, from concept through operating hardware.
- Translate process requirements into integrated designs for reactor vessels, crucibles, seals, and metal-handling mechanisms.
- Use first-principles calculations, simulation, and instrumented testing to validate heat transfer, thermal expansion, structural loads, and component life under repeated thermal cycling.
- Resolve heating, cooling, vacuum-integrity, and material-compatibility problems with the thermal and research teams.
- Radically simplify reactor assemblies, reduce part count, and standardize components for repeatable manufacturing.
- Own CAD models, fabrication drawings, tolerances, BOM, and equipment specifications.
- Work directly with fabricators and suppliers to reduce lead time and make reactors easier to assemble, service, and repair.
- Drive hands-on assembly, troubleshooting, and cold and hot testing of pilot and next-generation reactors.
- Define acceptance criteria, lead mechanical factory acceptance testing, and support installation and commissioning at Solcoa One.
- Lead a team of mechanical engineers, organize the mechanical design process, and conduct design reviews.
- Interface with fabrication, operations, and process teams to create mechanical design requirements and make key systematic design decisions.
Requirements
- Proficiency in CAD (Fusion).
- Hands-on experience with metal machining and shop tools.
- Experience with high-temperature systems and/or vacuum hardware.
- Detail-orientation and precise technical execution.
- Comfort working independently in a fast-paced, build-measure-learn environment.
- Availability to start soon.

About the Company
- 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.
