Position Overview:

MP Materials is seeking a hands-on senior process engineer to be an integral part of the team building and operating a new metal, alloy, and magnet-making facility in Fort Worth, Texas. The senior process engineer specializes in the surface finishing of components such as pre-treatment (i.e. cleaning, pickling) and coating (i.e. passivation, plating, epoxy coating etc.), wire slicing, grinding and chamfering. The role requires a combination of technical expertise, problem-solving skills, and collaborative abilities to drive the development and optimization of cleaning/coating process as well as wire slicing/grinding and chamfering operations. The ideal candidate will have hands-on experience in surface finishing/coating/plating/painting operations as we as some exposure to machining processes. The process engineer must be comfortable with failure analysis, continuous improvements, equipment fault diagnosis, and process development.

Position Responsibilities:

• Develop, optimize, and maintain coating process for Neodymium magnets.
• Implement process monitoring and control systems to maintain optimal coating conditions, maximize conformity, yield and throughput.
• Work with grinding/slicing engineers to hit throughput and process optimization goals.
• Collaborate with different teams and external vendors to operate, optimize and maintain coating and wastewater processing units.
• Troubleshoot equipment and process issues, root cause analysis, and implement corrective actions to resolve production disruptions and improve process robustness.
• Lead technical support and training to production personnels on coating techniques, equipment operation, and safety procedures.
  Lead process improvements, failure analysis, defect reduction, root cause analysis, and fault diagnostics.
• Define coating parameters, machine and bath specifications, and quality standards to ensure consistent production performance and adherence to customer requirements.
• Mentor and coach entry level engineers and technicians.
• Manage process improvement projects from concept to implementation, including scope, costing, justification, and verification.
• Other duties as assigned.

Basic Qualifications:

• Bachelor's degree in chemical engineering, chemistry, materials science and relevant field.
• 5-10 years of experience in process engineering roles focused on surface finishing, such as coating, plating, slicing and grinding.
• Experience of implementing statistical process control (SPC) for industrial manufacturing.
• Strong knowledge of surface finishing principles, chemistry and process engineering of coating/plating and industrial coating technologies.
• Experience of handling acidic, and alkaline baths and wastewater units for industrial coating/plating/paint technologies.
• Proficient with statistical analysis tools and methodologies for process optimization (e.g., Six Sigma, Design of Experiments, Root). Six sigma green belt would be preferred.
• 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.
