We have an opening for a materials scientist with experience in metallography and/or fractography. You will perform a full range of moderate to complex research in the area of metallography, sample preparation, microscopy, and materials characterization for a wide variety of projects at LLNL, including working with hazardous materials, e.g., radioactive materials, beryllium and lead. This position is in the Metallurgy and Advanced Microscopy Group in the Materials Science Division (MSD).

This position will be filled at either level based on knowledge and related experience as assessed by the hiring team. Additional job responsibilities (outlined below) will be assigned if hired at the higher level.

In this role you will

  • Conduct moderately complex to complex work in metallography, fractography, and materials characterization, including sample preparation, macro- and micro-hardness testing, optical microscopy, and scanning electron microscopy (including electron backscatter diffraction and energy/wavelength dispersive spectroscopy) for a variety of principal investigators at LLNL.
  • Contribute to the development and operation of metallography, sample preparation, and materials capabilities, including performing measurements, maintaining instruments, writing safety documentation, and upgrading equipment.
  • Independently develop moderately complex to complex methods for preparing and analyzing one-of-a-kind samples, including hazardous materials, beryllium, and radioactive materials.
  • Prepare written analyses, verbal briefings, and other products that capture and communicate research results.
  • Present research findings to sponsors and customers.
  • Contribute to and actively participate in the development of tools and techniques to achieve a high throughput of samples in the materials characterization laboratories.
  • Perform other duties as assigned.

Additional job responsibilities at the SES.3 Level

  • Conduct advanced development of sample preparation techniques using state-of-the-art automated equipment.
  • Serve as the primary technical contact on specific projects for LLNL customers.
  • Assist LLNL staff in planning and coordinating sample preparation and characterization across laboratories within the materials characterization center of MSD.

  • BS/BA in materials science, materials engineering, engineering technology, engineering science, mechanical engineering, chemical engineering, chemistry, or physics; or equivalent combination of education and extensive related experience. (AS/AA degree with experience is acceptable at the SES.2 level.)
  • Broad understanding of basic materials science and sample preparation concepts and skills, including sample polishing techniques, optical microscopy, scanning electron microscopy, macro- and micro hardness testing and grain size measurements.
  • Broad experience with preparation of metallographic specimens, including working with chemicals and etchants.
  • Experience with optical microscopy techniques.
  • Experience with Microsoft Office software, including Word, Excel, and PowerPoint.
  • Experience operating computers to collect, analyze, and document scientific results.
  • Ability to work independently, as well as a member of a team.
  • Proficient verbal and written communication skills necessary to interact with a diverse set of scientists, engineers, and other technical and administrative staff within a collaborative research and development environment.

Additional qualifications at the SES.3 level

  • Significant experience in advanced electron microscopy techniques.
  • Significant experience in materials characterization, including a theoretical understanding of techniques and limitations of the tools.
  • Advanced knowledge in advanced materials science concepts, including phase transformations, dislocations, alloying, crystal structure, and grain boundaries.

Qualifications We Desire

  • Experience with scanning electron microscopy techniques, including expertise in operating an SEM.
  • Experience in other materials preparation and characterization tools, such as x-ray diffraction, transmission electron microcopy, hardness testing, electropolishing, ion milling, vacuum coating, white-light interferometry, and density measurements.
  • Experience with instrument maintenance and design and fabrication of simple fixtures.
