Materials Scientist

Vulcan Elements is manufacturing American rare-earth permanent magnets for a secure, resilient future. With a focus on national security and economic resiliency, we serve critical industries such as defense, aerospace, and automotive powering a high-technology future. Vulcan Elements is building a team of ambitious professionals committed to Mission Focus, Technical Excellence and Transparency. 

As the Senior Material Scientist you will own the science connecting the metallic coatings that protect them from corrosion and the characterization work that proves it. This is an R&D role based at our Research Triangle Park lab, working in direct support of our Benson, NC manufacturing facility: you'll develop and qualify processes in the lab and on pilot-scale equipment, interface with external suppliers then hand off specifications the Benson production team runs at scale. You'll own key external coating supplier relationships. This is a hands-on, individual-contributor role with real influence over how a brand-new production facility is built and qualified. 

Responsibilities

• Develop, qualify, and optimize protective metallic, passivation, or polymer coatings (e.g., electroplated Ni, Zn, or Al-based systems, PVD/sputtered layers) for sintered NdFeB magnets to meet corrosion, adhesion, and thermal-performance specifications. 
• Design and run coating process experiments and correlate process variables to coating quality, adhesion strength, and salt-spray/humidity performance. 
• Perform materials characterization and failure analysis using SEM/EDS, XRD, optical microscopy, coating-thickness and adhesion testing, and accelerated corrosion testing (e.g., ASTM B117 salt spray) across both R&D and production samples. 
• Manage relationships with external coating suppliers and toll processors: qualify new vendors, audit their processes and quality systems, and coordinate outsourced coating runs to support production timelines and second-source strategy. 
• Partner with the powder metallurgy and process engineering teams to understand how upstream variables shape the finish and microstructure that coating performance and magnetic properties depend on. 
• Lead root-cause investigations for coating defects, corrosion failures, and quality escapes, and drive corrective and preventive actions through to closure, whether the issue originates in-house or at a supplier. 
• Author and maintain rigorous, operator-ready process documentation, test protocols, and supplier specifications that support scale-up and quality systems. 
• Present experimental results, process recommendations, and risk assessments to cross-functional partners and leadership. 
• Provide technical mentorship to junior engineers and lab technicians on coatings and materials-testing best practices.
