Process Engineer, Machining

MP Materials (NYSE: MP) is on a mission to restore the full rare earth supply chain to the United States of America. From electric cars to wind turbines and drones, rare earth magnets are essential to the low carbon, electrified technologies that power modern life. We hire ambitious, mission-driven people motivated to solve problems and affect change. Our values are grounded in teamwork, resiliency, and integrity, with an enduring commitment to our employees, community, and the environment. In the coming years, MP Materials will grow from a core materials and chemical processing company into a large industrial manufacturer. Our employees will lead this exciting transformation and grow professionally with us.

This job description outlines the key responsibilities and qualifications expected of a Process Engineer specializing in the machining of carbides and ceramics. The role requires a combination of technical expertise, problem-solving skills, and collaborative abilities to drive the development and optimization of machining processes for these challenging materials. The ideal candidate will have hands-on experience in machining metal/ceramic cutting and grinding operations. The Process Engineer must be comfortable with failure analysis, continuous improvements, equipment fault diagnosis, and process development.

The new facility will contain a broad range of chemical, mechanical, and thermal processes, including electrowinning, strip casting, powder production, pressing & sintering, machining, and assembly. Because of the broad range of processes in use, it is important that the Process Engineer be able to engage with a broad range of technical specialists and gain a working understanding of the physical processes, key control metrics, and potential hazards involved. The key aspect of this role is to provide technical coordination and support to the part machining operation to meet customer requirements.

Essential Duties:

• Develop and optimize machining processes for magnetic materials, including sawing, slicing, and grinding.
• Design and implement tooling solutions optimized for materials, considering factors such as tool wear, material removal rates, and surface finish requirements.
• Collaborate with design and manufacturing teams to provide input on material selection, component geometry, and machining feasibility during product development stages.
• Conduct feasibility studies and process simulations to evaluate the manufacturability of new designs and identify potential challenges or opportunities for improvement.
• Define machining parameters, tooling specifications, and quality standards to ensure consistent production performance and adherence to customer requirements.
• Implement process monitoring and control systems to maintain optimal machining conditions, minimize scrap rates, and maximize throughput.
• Troubleshoot machining issues, root cause analysis, and implement corrective actions to resolve production disruptions and improve process robustness.
• Provide technical support and training to production personnel on machining techniques, equipment operation, and safety procedures.

Qualifications:

• Bachelor’s degree in Mechanical Engineering, Materials Science, or a related field. Advanced degree preferred.
  Minimum of 5 years of experience in process engineering roles focused on machining, preferably with a specialization in carbides and ceramics.
• Strong knowledge of machining principles, cutting tool materials, and machining parameters relevant to carbide and ceramic materials.
• Proficiency in CAD/CAM software for toolpath generation and machining simulation (e.g., SolidWorks, AutoCAD, Mastercam).
• Experience with CNC machining centers, grinding machines, and other precision machining equipment.
• Familiarity with statistical analysis tools and methodologies for process optimization (e.g., Six Sigma, Design of Experiments).
• Excellent problem-solving skills and the ability to analyze complex technical issues and develop practical solutions.
• Effective communication skills and the ability to collaborate cross-functionally with engineering, manufacturing, and quality teams.
• Strong commitment to safety, quality, and continuous improvement initiatives.
