MP Materials Corp.•Fort Worth, TX

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 a hands-on, experienced Senior Instrumentation Engineer to join the team designing and building a state-of-the-art greenfield facility for rare earth metals, alloys, and magnets. This is a high-impact technical leadership role in shaping the instrumentation strategy for one of the most important advanced manufacturing facilities being developed in the U.S. The ideal candidate is a subject matter expert (SME) in industrial instrumentation who can lead technical design, standardization, vendor engagement, and project execution. You’ll guide and mentor engineers, help set instrumentation philosophy across the site, and directly influence critical process, electrical, and automation design decisions. Your work will improve safety, efficiency, cost effectiveness, and environmental performance across the facility.
