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 geoscientist to support the development and application of algorithms for predicting the compaction, strength and fracture of heterogeneous materials (both natural and man-made). You will routinely interact with professional colleagues, mid-level management and sponsors across and outside of the Laboratory. This position is in the Atmospheric, Earth and Energy Division.


Essential Duties

- Independently develop continuum constitutive models describing the complex response of porous and/or heterogeneous materials.
- Investigate mechanisms of failure and comminution of brittle heterogeneous materials including comminution/fracture.
- Develop/perform complex experiments at state-of-the-art facilities to compliment constitutive and mechanics models targeting strength and failure of brittle heterogeneous materials.
- Exert significant influence on technical objectives related to development of the several codes at the lab including: geodyn material library, ALE3D, GEOS, routinely interacting with mid-level management and internal and external sponsors.
- Publish research results in technical reports and peer-reviewed journals and present technical results at scientific conferences.
- Construct mesoscale simulations on HPC platforms from statistically significant topology or data and reduce results for comparison with experiments.
- Perform other duties as assigned.


Qualifications

- PhD in computational mechanics or closely related field, or the equivalent combination of education and related experience.
- Significant experience developing software for parallel unix/linux platforms within a rigorous version control system.
- Advanced knowledge of Finite Element (FE) methods.
- Advanced verbal and written communication skills necessary to create reports, publications and proposals, and to provide technical information and advice to management and other stakeholders, as well as interpersonal skills necessary to work in a diverse, multidisciplinary research team.
- Demonstrated ability to work independently on complex technical tasks, exert significant influence on technical objectives, provide in-depth analyses, and develop unique technical solutions.


Desired Qualifications

- Familiarity with the structure of the open source LLNL GEOS code framework.
- Experience working on problems related to shock compression of condensed matter.

 

Pre-Employment Drug Test:  External applicant(s) selected for this position will be required to pass a post-offer, pre-employment drug test.
 

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.
