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.

Nice To Haves

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

Responsibilities

Perform moderately complex to complex metallography, fractography, and materials characterization, including sample sectioning, mounting, grinding, and polishing, macro- and micro-hardness testing, optical microscopy, and scanning electron microscopy (SEM), including Electron Backscatter Diffraction (EBSD) and Energy-dispersive X-ray spectroscopy (EDS), Wavelength Dispersive X-ray Spectroscopy (WDS) as needed
Independently develop methods for preparing and analyzing one-of-a-kind samples, including hazardous and radioactive materials.
Conduct failure analysis activities, coordinate inputs from other characterization capabilities (as applicable), and communicate results to customers.
Maintain sample traceability from receipt through archiving, and prepare well-written data sheets, summaries, and reports.
Contribute to development and operation of sample preparation and characterization capabilities, including performing measurements and troubleshooting equipment, maintaining instruments and coordinating with vendors as needed, writing safety documentation and supporting safe work practices, and supporting equipment upgrades and process improvements
