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 2019 Best Places to Work by Glassdoor!

We have an opening for a Computational Scientist to perform research and development of advanced finite element methods for multi-physics simulation codes based on partial differential equations (PDEs) in support of the Laboratory’s national security mission.

You will work independently as a technical expert on a code development team to advance the state of the art in large-scale multi-physics simulation for use in high-performance computing on the latest large-scale parallel computing platforms.

This position is in the Computing Directorate within the Center for Applied Scientific Computing (CASC) Division.
 
Essential Duties
- Propose, implement, and analyze complex models and numerical algorithms for PDEs to support multi-physics simulation capabilities based on requirements from a diverse user community.
- Design and implement advanced finite element methods and software tools as a technical expert on a multi-disciplinary team.
- Solve abstract problems/ideas creating complex and dynamic algorithms/software modules.
- Provide solutions to complex problems that require in-depth analysis of multiple factors and the creative use of established methods; prioritize many complex parallel tasks.
- 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.
- Significant experience in advanced finite element discretization, including experience with vector finite elements.
- Advanced knowledge of methods used to develop and perform numerical algorithms and conduct independent research.
- Significant experience in applying numerical methods within a scientific application.
- Significant experience programming in C/C++ in a Linux environment, using high-performance numerical software packages, and developing algorithms for massively parallel computer architectures.
- Advanced 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.
- Advanced verbal and written communication skills necessary to collaborate effectively in a team environment, author technical and scientific reports and publications, deliver scientific presentations, and provide advice to management.

 

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.
