About The Position

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.

MP Materials is seeking an Engineer to join the Magnet Technology group to support development technologies for advanced manufacturing to produce high-performance rare earth permanent magnets. In this role, the Engineer will conduct hands-on experiments to optimize the materials and processing of magnets, including casting, powder processing, pressing, sintering, recycling, and more. Responsibilities include designing custom experimental setups, running experimental campaigns on pilot-scale equipment, and materials characterization using techniques such as magnetometry, microscopy, and chemical analysis. The Engineer will work with process and product development engineers and technicians to deliver new, scalable technologies for manufacturing rare-earth permanent magnets. This is a rare opportunity to play a key role in returning an essential manufacturing capability to the USA.
