Join us and make YOUR mark on the World!

Come join Lawrence Livermore National Laboratory (LLNL) where we apply science and technology to make the world a safer place; now one of 2020 Best Places to Work by Glassdoor!

The Material Sciences Division (MSD) in the Physical and Life Sciences (PLS) Directorate has an opening for a Postdoctoral Researcher to perform scientific research in a National Laboratory setting. You will engage with a multi-disciplinary team developing advanced numerical and physical approaches to studying reacting flows in conditions of extreme temperatures and pressures.  You will apply techniques of machine learning, on-demand multiscale simulation, and numerical analysis to developing large scale scientific code applications that run efficiently on heterogeneous computer architectures.  A variety of applicant backgrounds are encouraged to apply including those with significant experience in one or more of the following areas: Chemistry, computer science, chemical engineering, mechanical engineering, and physics. This position is in the Macroscopic Modeling team within the Reaction Dynamics Group.

Essential Duties 
- Conduct fundamental research while developing state advanced numerical approaches to efficiently simulate chemical processes and high explosive detonations on heterogeneous computer architectures.
- Develop fundamental reaction mechanisms for high explosive shock initiation based on sub-scale simulations and experiments.
- Contribute to and actively participate in the conception, design, and execution of research to address defined problems.
- Pursue independent, complementary research interests and interact with a broad spectrum of scientists internally and externally to the Laboratory.
- Collaborate with scientists in a multidisciplinary team environment to accomplish research goals.
- Document research; write and publish papers in peer-reviewed journals, and present results within the DOE community, at working group meetings, and at conferences.
- Perform other duties as assigned.

- Recent PhD in physics, chemistry, computer science, materials science, engineering or related fields.
- Experience in developing advanced numerical simulation techniques for heterogeneous architectures.
- Experience in conceiving and implementing numerical methods in a high-level language (e.g., Fortran, C++, other).
- Experience either using computational modeling tools or programming languages to interpret experimental datasets.
- Proficient verbal and written communication skills as reflected in well-written published papers and effective presentations at seminars, meetings and/or teaching lectures.
- Initiative and interpersonal skills with desire and ability to work in a collaborative, multidisciplinary team environment.
Desired Qualifications
- Experience in using scripting languages (e.g., Perl, Python, other) for automation and analysis. 
- Experience in algorithmic development within a large software suite. 
- Knowledge of shock wave physics. Experience in implementing chemical reaction mechanisms into hydrodynamic simulations.

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.

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.  Q-level 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.

Note:   This is a 2 year Postdoctoral appointment with the possibility of extension to a maximum of 1 year.  Eligible candidates are those who have been awarded a PhD at time of hire date.
