Senior Engineer, Magnet Technology

Position 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—which supports next-generation technologies in robotics, automation, aerospace, transportation, defense, and energy systems.

MP Materials is seeking a hands-on Senior Engineer to join the Magnet Technology group to support development technologies for advanced manufacturing of high-performance rare earth permanent magnets. This role involves hands-on experimental development—including techniques such as strip casting, powder processing, pressing, and sintering—as well as designing custom experimental setups, running pilot-scale campaigns, and performing materials characterization. You will also provide technical leadership to junior engineers and technicians, drive cross-functional collaboration with production teams, and set technical directions for future process improvements. This is a rare opportunity to play a key role in returning an essential manufacturing capability to the USA.

Key Responsibilities

• Lead experimental projects, overseeing project planning, execution, and delivery of scalable new materials and processes for rare-earth permanent magnets.
• Design and conduct experiments to optimize new materials and processes for rare-earth permanent magnets.
• Leverage materials characterization techniques including SEM, XRD, and particle size analysis to suggest actionable process improvements.
• Collaborate with production teams to scale processes from pilot to full manufacturing operations.
• Mentor technicians and engineers, providing technical guidance in metallurgical materials and fostering a culture of continuous learning.
• Generate technical reports and SOPs, document findings, and build team knowledge of current and future magnet prototyping.
• Work closely with EHS to ensure world-class health and safety and full compliance with environmental regulations.
• Perform other duties as assigned.

Required Qualifications

• Master’s or Ph.D. in Materials Science & Engineering, Metallurgy, Mechanical Engineering, or a related field.
• 5+ years of experience in manufacturing or R&D with a proven track record in process development across metals, ceramics, or related systems.
• Strong knowledge and hands-on experience with process development in casting, powder metallurgy, pressing, or sintering.
• Proficiency in materials characterization techniques such as XRD, SEM, and particle size analysis.
• Demonstrated ability to design and execute experiments, analyze data, and draw actionable conclusions.
• Excellent written and verbal communication skills.

Preferred Qualifications

• Experience with manufacturing rare earth materials and permanent magnets.
• Strong troubleshooting skills with manufacturing equipment and process control.
• Experience in leading technical development projects, with the ability to prioritize and manage multiple concurrent projects.
• Proficiency in analyzing experimental data using tools such as Python, MATLAB, or statistical software.
• Enthusiastic lifelong learner, eager to apply existing skills and experiences to new challenges.
