MP Materials (NYSE: MP) is rebuilding American industrial capability for a new era of autonomy, robotics, and electrification. We are the only U.S. company with a fully integrated rare earth supply chain—from mining and refining to advanced metal and magnet manufacturing. Our products include both the critical materials used to make permanent magnets and the finished magnets themselves—enabling next-generation technologies in robotics, automation, aerospace, transportation, defense, and energy systems.

These materials are the foundation of physical AI—the convergence of computation, movement, and control.

We are seeking a hands‑on Senior Technician to support the Magnet Technology group in developing advanced manufacturing technologies for high‑performance rare earth permanent magnets. The Senior Technician will take a lead role in executing experimental trials, operating and maintaining pilot plant equipment, preparing and testing materials, and training and guiding junior technicians.
