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 openings for computational physicists to pursue challenges relevant to national security in the development of multi-physics simulation codes. You will collaborate as part of an interdisciplinary code development team in advancing the state of the art in large-scale multi-physics simulation. The national security mission involves developing simulation capabilities for Stockpile Stewardship, nuclear counter-terrorism, conventional weapons, and high energy density physics experiments. The code development focus is on models and algorithms for use in high-performance computing on the latest large-scale parallel computing platforms. This position is in the Design Physics Division within the Weapons and Complex Integration (WCI) Directorate.

 

This position will be filled at either the SES.2 or SES.3 level depending on your qualifications. Additional job responsibilities (outlined below) will be assigned if you are selected at the higher level.

 
Essential Duties
- Develop, release, and maintain models and algorithms using advanced simulation tools to support the physics capabilities based on requirements from a diverse user community.

- Provide technical support, informal training, and guidance to code users in the application of simulation tools developed.

- Participate in the development of simulation tools as part of a multi-disciplinary team.

- Present and disseminate research results at scientific conferences and in peer-reviewed publications, in both open and classified environments, internal and external to LLNL. Responsibilities may also include interacting with external stakeholders, both at NNSA and across the broader interagency, via offsite assignments.

- Perform other duties as assigned.
In Addition at the SES.3 Level
-Develop, assess and provide in depth analysis of the physics capabilities in support of nuclear weapons simulations using advanced simulation tools to solve complex problems that may not be well defined.

- Collaborate as a technical expert on multidisciplinary team.

- Set specific technical strategies to achieve program goals.

 
Qualifications

- PhD in physics, mathematics, engineering, or related field or the equivalent combination of education and related experience.

- Demonstrated technical mastery in one or more science disciplines, such as shock hydrodynamics, fluid mechanics, material behavior, particle transport, radiation transport, plasma physics or chemical processes.

- Experience converting theory into models, implementing models, and evaluating algorithms and methods for their fitness for a particular task, as well as developing new numerical algorithms.

- Experience developing and supporting multi-dimensional numerical simulation.

- Demonstrated creativity and innovation in approaching challenging technical problems.

- Experience with programming in Python, FORTRAN, C and/or C++ on high-performance and/or heterogenous computer systems.

- Experience working independently and in a multi-disciplinary team-research environment, demonstrating self-motivation and initiative in addressing challenging problems.

- Demonstrated verbal and written communication and presentation skills necessary to author technical and scientific reports, publications, invited papers, and to deliver scientific presentations.

In Addition at the SES.3 Level

- Advanced knowledge of physics, mathematics, aerospace or nuclear engineering or a related field.

- Significant experience leading or mentoring as part of a multidisciplinary team.

- Demonstrated record of delivering top-quality research in relevant areas of physics and engineering.

Pre-Placement Medical Exam:  A job related pre-placement medical examination may be required.

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 listing has multiple openings; these are Career Indefinite positions.  Lab employees and external candidates may be considered for these positions.
