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 Computational Scientist to perform research and development of advanced methods for multi-scale, multi-physics simulation codes in support of the Laboratory’s national security mission. You will work independently as a technical expert on a code development team, focusing on models and algorithms for use in high-performance computing on the latest large-scale parallel computing platforms in advancing the state of the art in large-scale multi-physics simulation; the scope of work involves many parallel tasks requiring prioritization. This position is in the Computation Directorate within the Center for Applied Scientific Computing (CASC) Division.
 
Essential Duties
-Propose, implement and analyze numerical algorithms to support multi-scale, multi-physics simulation capabilities based on requirements from a diverse user community.
- Design and implement simulation tools as part of a multi-disciplinary team.
- Solve abstract complex problems/ideas creating highly complex and dynamic algorithms/software modules.
- Provide solutions that require in-depth analysis of multiple factors and the creative use of established methods.
- Provide informal training, and guidance/support to code users in the application of simulation tools developed.
- Establish and conduct independent research projects and collaborate with a broad spectrum of scientists internally and externally to accomplish research goals.
- Present and disseminate research results at scientific conferences and in peer-reviewed publications, in both open and classified environments, internal and external to LLNL.
- Perform other duties as assigned.
 
Qualifications
- Ph.D. in applied mathematics, computational physics or engineering, or a related field or the equivalent combination of education and related experience.
- Subject matter expertise in one or more computational science disciplines, such as shock hydrodynamics, fluid mechanics, material behavior, particle transport, radiation transport, plasma physics or chemical processes.
- Substantial experience developing and performing analysis of numerical algorithms and conducting independent research.
- Highly advanced experience in applying numerical methods within a scientific application.
- Substantial experience programming in C/C++ in a Linux environment, using high-performance numerical software packages, and developing algorithms for massively-parallel computer architectures.
- Expert analytical, problem-solving, and decision-making skills to develop creative solutions to complex problems.
-Ability to work independently while effectively managing concurrent technical tasks with competing priorities.
- Expert verbal and written communication and interpersonal skills necessary to effectively collaborate with internal and external teams to present and explain technical information and advise senior management; as well as diplomatic communication skills for interactions with sponsors/customers, and multi-lab teams.
 

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 Career Indefinite position. Lab employees and external candidates may be considered for this position.
