• Create and deliver advanced training, technical guidance, and documentation for users and staff in specialized metallurgical methods and best practices.

• Ability to obtain and maintain a U.S. DOE Q-level security clearance, which requires U.S. citizenship.
• Bachelors in materials science, materials engineering, engineering technology, engineering science, mechanical engineering, chemical engineering, chemistry, physics, or equivalent combination of education and related experience.
• Significant metallurgical lab experience or related functions, (e.g.- metallography experience in aerospace, defense, or medical implant industry)
• Demonstrated broad understanding of materials science and sample preparation concepts, including polishing techniques, optical microscopy, hardness testing, and grain size measurements.
• Broad experience preparing metallographic specimens, including working with chemicals and etchants (chemical and/or electro-etching).
• Experience with optical microscopy techniques.
• Experience using computers to collect, analyze, and document scientific results, including proficiency with Microsoft Office (Word, Excel, PowerPoint).
• Demonstrated ability to work independently and as part of a team.
• Expert verbal and written communication skills to interact effectively with scientists, engineers, and other staff in a collaborative R&D environment.
• Significant experience in materials characterization, including theoretical understanding of methods and tool limitations.
• Demonstrated advanced knowledge of materials science concepts such as phase transformations, dislocations, alloying, crystal structure, and grain boundaries.
• Training fellow staff members in advanced metallography skills and concepts.

In addition, at the SES.4 level

• Experience with hardness testing beyond microhardness (for example Rockwell), tensile testing, weld/braze analysis, thermal spray analysis, heat treating.
• Experience with instrument maintenance and designing/fabricating simple fixtures.
• Significant experience operating and applying SEM techniques, including hands-on SEM operations.
• Demonstrated knowledge of quality control practices and day-to-day operations in a certified laboratory, including familiarity with applicable laboratory standards (for example, ISO/IEC 17025).
• Significant experience with additional preparation and characterization tools such as: X-ray diffraction (XRD), transmission electron microscopy (TEM), focused ion beam (FIB) (as applicable), electropolishing, ion milling, vacuum coating, and white-light interferometry, density measurements
