Join us and make YOUR mark on the World!
Are you interested in joining some of the brightest talent in the world to strengthen the United States’ security? Come join Lawrence Livermore National Laboratory (LLNL) where our employees apply their expertise to create solutions for BIG ideas that make our world a better place.
We are committed to a diverse and equitable workforce with an inclusive culture that values and celebrates the diversity of our people, talents, ideas, experiences, and perspectives. This is important for continued success of the Laboratory’s mission.
We have an opening for a Postdoctoral Researcher in metal additive manufacturing (AM) with an emphasis on the development and understanding of AM process optimization, alloy design, and compositional grading in AM components. Critical aspects of the work will include the use of metal AM equipment and advanced electron microscopy techniques to characterize the components. You will actively participate with and be an integral member of an interdisciplinary team working on advanced manufacturing science, particularly in the context of understanding the response of additively manufactured components to accelerate qualification of AM components. This position is in the Metallurgy and Advanced Microscopy group of the Materials Science Division.
- Provide knowledge of topics, including laser-matter interaction science, alloy design and alloying effects, fundamental metallurgy such as solidification and phase transformations, and thermomechanical response in metal AM components.
- Perform characterization of metal AM components with mechanical testing (tensile, compressive, and dynamic) and microscopy, including optical, SEM, EBSD, and EDS.
- Design and perform complex experiments; collect and analyze resulting multimodal datasets.
- Collaborate with scientists in a multidisciplinary, cross-functional team environment to accomplish research goals.
- Pursue independent but complementary research interests and interact with a broad spectrum of scientists internally and externally to the Laboratory.
- Document research, publish papers in high-impact peer-reviewed scientific journals, and present results within the DOE community and at conferences.
- Maintain and establish laboratory protocols, including adherence to safety and security protocols.
- Perform other duties as assigned.
- Ph.D. in Material Science, Physics, Chemistry, Mechanical Engineering, Chemical Engineering, or related field.
- Broad experience with materials characterization techniques, including scanning/transmission electron microscopy (SEM, TEM) techniques (backscatter imaging, electron backscatter diffraction (EBSD), energy dispersive spectroscopy (EDS), in situ testing and analysis.
- Experience with mechanical testing.
- Experience preparing samples for metallographic characterization, including sectioning, cutting, grinding, mechanical polishing, and electrochemical etching or polishing.
- Experience analyzing defects and microstructures in additively manufactured metals.
- Ability as an innovative experimentalist with a broad range of experience in experimental design, techniques, and execution.
- Initiative and interpersonal skills necessary to interact with a diverse set of scientists, engineers, and other technical and administrative staff, with the ability to work independently as well as in multidisciplinary research teams.
- Proficient written and verbal communication skills with demonstrated capabilities in delivering presentations and preparing written reports.
Qualifications We Desire
- Experience with metals processing, including the operation of metal additive manufacturing equipment.
- Experience in computer programming for data analysis (e.g., Python, Matlab).
All your information will be kept confidential according to EEO guidelines.
This is a Postdoctoral appointment with the possibility of extension to a maximum of three years, open to those who have been awarded a PhD at time of hire date.
