Company Description

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 essential to innovation and creativity for continued success of the Laboratory’s mission.

Job Description

We have an opening for a Research Scientist to conduct operations and research in the areas of low temperature physics and condensed hydrogen. You will actively participate in the research and development and advanced process development in areas such as solid hydrogen crystal growth for Inertial Confinement Fusion applications, and various characterization methods and be an integral member of an interdisciplinary team in the LLNL Targets group support. Targets are intricate assemblies of numerous finely manufactured components and are comprised of the essential elements of experiments on high energy density (HED) plasma generating systems such as the National Ignition Facility (NIF).  Consequently, they raise many interesting challenges whose resolution requires a combination of materials physics and engineering as well as metrology science with a strong sense of real-world implementation of reliable new processes. This position is in the NIF Optics and Materials Group of the Materials Science Division.

In this role you will 

  • Design and conduct advanced cryogenic experiments with condensed hydrogens and other critical Targets related tasks that drive the program forward.
  • Develop optical, X-ray, or other non-contact characterization methods.
  • Develop software scripts to perform these experiments and test specific image processing and feature detection algorithms.
  • Collaborate in the design, modeling, and analysis of laboratory experiments and develop experimental apparatus, advanced measurement instrumentation, and procedures as required.
  • Collaborate with scientists in multidisciplinary team environment to accomplish research goals.
  • Document research and 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.


  • Ability to secure and maintain a U.S. DOE Q-level security clearance, which requires U.S. citizenship.
  • PhD in Physics, Chemical Engineering, Mechanical Engineering, Materials Science or a related field, or the equivalent combination of education and relevant experience.
  • Significant experience with cryogenic experiments and/or vacuum hardware.
  • Advanced programming experience in C, C++ or languages (such as Matlab, Python).
  • Familiarity with optics and X-ray phase contrast and related techniques and image analysis principles.
  • Ability as an innovative experimentalist with experience in experimental design, techniques, and execution, and willingness to work on a variety of projects and learn new techniques.
  • Advanced verbal and written communication skills as reflected in effective presentations at seminars, meetings and/or teaching lectures, writing reports, publications, and proposals.

Qualifications We Desire

  • Experience working in the fields of crystal growth techniques, surface science, or related fields.
  • Significant experience in nucleation and crystal growth science.
