Science and Technology on a Mission!

For more than 60 years, the Lawrence Livermore National Laboratory (LLNL) has applied science and technology to make the world a safer place.

We have an opening for a postdoctoral researcher to conduct research in nuclear nonproliferation, threat detection, and analysis.  You will participate in the development of new detection systems and algorithms, and also implementing these new technologies in actively deployed systems. This position is in the Nuclear Security Physics group of the Nuclear and Chemical Sciences Division.

Essential Duties
– Participate in the development, design, implementation, fabrication, evaluation, and analysis of new algorithms and instrumentation for the detection, classification, identification, localization and tracking of nuclear materials or objects of concern.
– Work with partners outside LLNL to deploy and test algorithms on next-generation radiation detection systems.
– Document and publish research results in peer-reviewed scientific or technical
journals and present results at external conferences seminars and/or technical meetings.
– Pursue independent (but complementary) research interests and interact with a broad spectrum of scientists internally and externally.
– Perform other duties as assigned.

– Recent PhD in physics, nuclear engineering or related field.
– Experience in some of the following fields: nuclear physics, astrophysics, high energy physics, nuclear engineering, radiation transport and measurement modeling, gamma-ray spectroscopy, nuclear instrumentation, statistics, signal processing, electrical engineering, computer science, and machine learning.
– Ability to perform independent research in experimental or theoretical science or engineering.
– Experience with computer programming.
– Ability to find innovative solutions to scientific and technical problems.
– Documented publication record in peer-reviewed literature with experience presenting research results to a large audience.
– Proficient verbal and written communications skills necessary to author technical and scientific reports and publications, and deliver scientific presentations.
– Initiative and interpersonal skills with desire and ability to work in a collaborative, multidisciplinary team environment.

Desired Qualifications
– Experience in Monte Carlo and/or deterministic radiation transport codes (e.g. MCNP, GEANT etc.).
– Experience in MATLAB, Python, Java, C++, and/or SQL databases.
– Experience in Gamma-ray and/or neutron imaging systems.

Pre-Employment Drug Test:  External applicant(s) selected for this position will be required to pass a post-offer, pre-employment drug test.
Security Clearance:  This position requires a Department of Energy (DOE) Q-level clearance.

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.  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.


Note:   This is a two-year Postdoctoral appointment with the possibility of extension to a maximum of three years.  Eligible candidates are recent PhDs within five years of the month of the degree award at time of hire date.
