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 Postdoctoral Researcher in the field of computational plasma physics to advance simulation capabilities for pulsed power drivers.  The position involves application of high-fidelity kinetic models to understand microscale plasma dynamics in pulsed power experiments and to enable breakthroughs in predictive modeling. Importantly, the position involves development of parallel high-order accurate numerical algorithms that leverage exascale-class computing platforms to facilitate high performance simulations of experimental conditions.  This position is in National Security Engineering Division (NSED) within the Engineering Directorate.

In this role you will 

  • Research and develop algorithms for solving high-fidelity plasma physics models so as to exploit exascale-class computer architectures and enable investigations of power flow physics in pulsed power drivers.
  • Research, apply, evaluate, and test parallel programming models and C++ libraries that facilitate memory management and enable numerical solvers to run efficiently on heterogeneous exascale computing architectures.
  • Work with domain experts to apply simulation capabilities to advance scientific understanding of power flow physics.
  • Document key research findings through publications in peer-reviewed journals and conference presentations.
  • Coordinate with internal and external scientists to maximize impact and relevance of R&D.
  • Perform other duties as assigned.

Qualifications

  • Ability to secure and maintain a U.S. DOE Q-level security clearance which requires U.S. citizenship.
  • Ph.D. in Scientific Computing, Computational Physics, Applied Mathematics, or a related computational science and engineering discipline.
  • Experience with programming in C/C++.
  • Experience with high-performance computing, parallel programming, and GPU programming.
  • Familiarity with numerical methods for solving partial differential equations.
  • Demonstrated ability to conduct original and independent research through a proven track record of scientific accomplishments.
  • Advanced written and verbal communication skills necessary to interact with a multidisciplinary research team, author technical and scientific reports and papers, and deliver technical presentations.

Qualifications We Desire

  • Experience in the fields of pulsed power and/or plasma physics.

Security Clearance

LLNL is a Department of Energy (DOE) and National Nuclear Security Administration (NNSA) Laboratory.  Some positions will require a DOE L or Q clearance (please reference Security Clearance requirement above).  If you are selected and a clearance is required, 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.  For additional information please see DOE Order 472.2.

Pre-Employment Drug Test

External applicant(s) selected for this position will be required to pass a post-offer, pre-employment drug test. This includes testing for use of marijuana as Federal Law applies to us as a Federal Contractor.
