Join us and make YOUR mark on the World!

Lawrence Livermore National Laboratory (LLNL) has turned bold ideas into world-changing impact advancing science and technology to strengthen U.S. security and promote global stability.

Our mission spans four critical national security areas nuclear deterrence, threat preparedness, energy security, and multi-domain defense empowering teams to take on the toughest challenges of today and tomorrow. With a culture built on innovation and operational excellence, LLNL is a place where your expertise can make a real impact.

We have multiple openings for postdoctoral researchers in our Advanced Manufacturing and Materials Processing Section. You will collaborate with a team of engineers and scientists who design and test microarchitected metamaterials and formulate related feed stocks. Specifically, you will develop design tools, additive manufacturing techniques, two-photon lithography fabrication methods, and/or microscale analysis methods for lattices with microscale features. These positions are within the Materials Engineering Division (MED) of the Engineering Directorate.

This position requires full-time on-site presence due to the nature of the work.

You will:

• Conduct research and development in one or more of the following areas: architected materials, additive and advanced manufacturing, and microscale materials testing. Design, implement, and analyze techniques in one or more of these areas.
• Organize, analyze, and present research data.
• Contribute to and actively participate in the conception, design, and execution of research to address defined problems.
• Pursue independent, yet complementary, research interests and interact with a broad spectrum of scientists both within and outside the Laboratory.
• Collaborate with others in a multidisciplinary team environment to accomplish research goals.
• Publish research results in peer-reviewed scientific or technical journals and present results at external conferences, seminars, and/or technical meetings.
• Perform other duties as assigned.

• PhD in mechanical engineering, chemical engineering, polymer engineering, materials science, or a related field.
• Experience in one or more of the following areas: metamaterial design, additive manufacturing/3D printing, feedstock formulation and characterization, finite element analysis, and materials testing.
• Demonstrated ability to serve as an innovative experimentalist with broad experience in experimental design, techniques, and execution.
• Ability to develop independent research projects, as demonstrated through peer-reviewed publications.
• Proficient verbal and written communication skills, with the ability to collaborate effectively in a team environment and present and explain technical information.
• Initiative, interpersonal skills, and the ability to work in a collaborative, multidisciplinary team environment.

Desired Qualifications

• Experience with analytical and computational modeling and simulation, as well as data analysis.
• Experience with materials characterization and mechanical testing, such as tensile and compression testing, three-point bending, rheometry, FTIR, DMA, DSC, and SEM/TEM.
• Experience with programming languages such as LabVIEW, MATLAB, Python, and C/C++.
