Supervisor, Prototyping

Company Overview:

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 hire ambitious, mission-driven people who want to tackle complex challenges and shape the future of strategic industries. Our culture is rooted in teamwork, resiliency, and integrity, with a deep commitment to operational excellence and national purpose. MP is rapidly evolving from a materials producer into a leading U.S. manufacturer—and our people are driving that transformation.

We are seeking a hands-on Supervisor to support the Magnet Technology group in developing advanced manufacturing technologies for high-performance rare earth permanent magnets. The Supervisor will be responsible for leading a team of technicians that will transform raw materials into finished rare earth magnets at a pilot-scale operation. The Supervisor will plan and manage resources across the end-to-end magnet making processes to meet the pilot plant production schedule.

This is a rare opportunity to play a key role in returning an essential manufacturing capability to the USA.
