Los Alamos National Laboratory Continuum Solid Mechanics Computational Scientist 4 (Scientist 4) in Los Alamos, New Mexico


Job Title Continuum Solid Mechanics Computational Scientist 4 (Scientist 4)

Location Los Alamos, NM, US

Organization Name Methods And Algorithms (XCP-4)

What You Will Do

The Methods and Algorithms Group (XCP-4) of the Computational Physics Division at Los Alamos National Laboratory is seeking outstanding candidates for positions at the Scientist 4 level in the area of continuum solid mechanics modeling. The successful candidates are expected to provide direction and vision, lead in a team environment, look for new opportunities to expand this research area in the group, implement, test and verify their models and algorithms in large production software and publish their research in leading scientific journals.

XCP-4 is a group of about 20 scientists with various technical backgrounds doing cutting edge research in advanced computational methods and algorithms for multi-physics applications in support of national and global security. Specifically, we develop state-of-the art numerical methods for shock hydrodynamics and multiphase flow in both Eulerian and Lagrangian frameworks, as well as advanced physics-based computational models in a variety of areas, including high explosives, turbulent reactive flow, and continuum solid mechanics. Our staff provide expertise in these areas through multidisciplinary interactions on teams seeking to provide solutions for large multi-physics codes. Our work supports a variety of Laboratory missions, including stockpile stewardship, nonproliferation, threat reduction, and energy and environmental sciences.

What You Need

Minimum Job Requirements:

  • Expertise in continuum-level modeling of polycrystalline materials under dynamic (shock) loading, including strength and damage/cavitation behavior, the mechanics of brittle fracture and/or porous or granular materials as well as the behavior of multiphase and/or composite materials, and high-order numerical methods and algorithms associated with these areas, especially with respect to Lagrangian and/or Eulerian frameworks

  • Experience with phase transition (solid-solid and solid-liquid) kinetics models in the context of continuum-level solid mechanics modeling

  • Understanding of hypo- and hyper-elastic/plastic solid state models

  • Experience in developing accurate and robust numerical methods for multiphysics simulation software at the continuum scale using finite- volume and/or finite element methods in a programming language such as Fortran, C/C++, and/or Python

  • Experience with theoretical model development

  • Experience in Verification and Validation techniques

  • Proven leadership experience (such as principal investigator) in the broad area of modeling and simulation

  • Demonstrated experience developing innovative scientific solutions by integrating technical knowledge across disciplines and/or people for complex multi-physics problems

  • Sustained scientific accomplishments and national recognition as demonstrated through awards and publication record in the field of theoretical and computational physics for shock detonation, reactive flow and/or high explosives.

  • Demonstrated ability to communicate effectively both written and orally, interpersonal and to large audiences

  • 10+ years of relevant R&D experience

  • Ability to obtain a Q Clearance, which usually requires US Citizenship

Desired Skills:

  • Experience with atomic-level/microscopic physics leading to material behavior, such as crystal plasticity, and creation of sub-grid models or other techniques of mapping these types of models up to the continuum level

  • Experience with LANL X-Division Codes

  • Experience with large-scale projects to solve national technology challenges

  • Familiarity with the NNSA National Laboratories’ mission and research environment, in particular LANL ASC and global security programs

  • Knowledge of nuclear weapon physics

  • Experience in developing and running large, parallel codes in a high- performance, Unix computing environment for many-core architectures

  • Active DOE Q Clearance

Education: Master's degree in Physics, Materials Science, Engineering, Applied Mathematics, or related field; PhD in Physics, Materials Science, Engineering, Applied Mathematics, or related field preferred. Postdoctoral research experience is preferred.
