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 looking for individuals that demonstrate an understanding of working in partnership with team peers, who engage, advocate, and contribute to building an inclusive culture, and provide expertise to solve challenging problems.

Job Description

We have an opening for our prestigious and distinguished Dr. Harold Brown Postdoctoral Fellowship in the Weapons and Complex Integration (WCI) Directorate.  Named after the Laboratory’s renowned physicist Dr. Harold Brown, this fellowship recognizes individuals whose research aligns with the Laboratory’s national security mission. Dr. Brown was a nuclear deterrence pioneer and a former Lawrence Livermore National Laboratory director, as well as Secretary of Defense under President Jimmy Carter. An intellectual giant who led development of technologies that modernized nuclear deterrence and played integral roles during the most dramatic moments of the Cold War, Dr. Brown’s life was indelibly intertwined with national security. This prestigious postdoctoral position will allow you to take your skills to the next level and apply them to solving the nation’s most pressing science and engineering challenges. The purpose of this fellowship is to pursue groundbreaking science and to stimulate ideas for cross fertilization. Harold Brown Fellows will participate in creative and independent research in an aspect of science and engineering relevant to the competencies at LLNL. Harold Brown Fellows participate in experimental, computational, and/or theoretical work, and will have access to LLNL's extensive computing facilities, talent pool, specialized laboratory facilities and field equipment.

We invite PhD graduates from a variety of STEM fields (including, but not limited to, the various physics disciplines, engineering, experimental science, computational sciences, planetary science, chemistry, or material science) to apply for this distinguished Harold Brown Postdoctoral Fellowship.  We will work with successful candidates to tailor a postdoctoral project and select a mentor to support each individual’s development.  This opportunity is intended for individuals who have finished their PhD and wish to further develop their skills, knowledge, and/or abilities to better position themselves for a future staff position within the Design Physics Division or elsewhere in LLNL.

We select the highest qualified candidates based on demonstrated research aptitude and then customize the project assignment to fit their abilities and interests as well as our needs. Recent projects have involved the physics of inertial confinement fusion, turbulence and fluid instabilities, atomistic and continuum models of transport, planetary defense, diagnostic development, computational solid and fluid dynamics, chemical physics, particle and radiation transport algorithm development, and uncertainty quantification. This position is in the Design Physics Division (DPD) within the WCI Directorate.

Security Clearance

LLNL is a Department of Energy (DOE) and National Nuclear Security Administration (NNSA) Laboratory.  Most positions will require a DOE L or Q clearance (please reference Security Clearance requirement).  If you are selected, we will initiate a Federal background investigation to determine if you meet eligibility requirements for access to classified information or matter. In addition, all L or Q cleared employees are subject to random drug testing.  An L or Q clearance requires U.S. citizenship.  If you hold multiple citizenships (U.S. and another country), you may be required to renounce your non-U.S. citizenship before a DOE L or Q clearance will be processed/granted.  For additional information please see DOE Order 472.2.
