Senior Engineer, Applications Engineering

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.

The Senior Applications Engineer will have a technical background and will understand how customers use the unique properties of rare earth permanent magnets across a variety of end use applications. They will be familiar with the broad range of chemical, thermal, and mechanical, and thermal processes used to produce magnets, magnet assemblies, and electric motors. They will be experienced at working with customers in the design and quoting process.

They will also have experience building the underlying tools and systems to support these processes. In addition to responding to requests from current and prospective customers, the successful candidate will play a critical role in identifying current and future product value by synthesizing customer needs and market trends. This is an opportunity to be a part of building our team, our factory, and our culture as the Magnetics team helps to define the future of American manufacturing.
