Department Description:

The Multi-Physics Modeling and Simulation Department at Sandia National Laboratories, California, conducts a wide range of computational simulations, including linear-elastic static; large-deformation, nonlinear structural dynamics; hydrodynamics; and solid mechanics. To complete these simulations, the department uses a variety of state-of-the-art analytical tools. Typical departmental programs include the following: detailed structural and thermal analyses of weapon systems; analysis-based design guidance for weapon components; the development of forging and welding modeling capabilities; pressure vessel analyses, including aging and failure; hydrodynamics modeling and simulations; and failure model development and implementation (metals and composites). In addition, a current major departmental focus is the development of science-based failure models and mesh-convergent numerical methodologies.

Security Clearance:

Position requires a Department of Energy (DOE) Q-level security clearance.

Sandia is required by DOE to conduct a pre-employment drug test and background review that includes checks of personal references, credit, law enforcement records, and employment/education verifications. Applicants for employment must be able to obtain and maintain a DOE Q-level security clearance, which requires U.S. citizenship. If you hold more than one citizenship (i.e., of the U.S. and another country), your ability to obtain a security clearance may be impacted.

Applicants offered employment with Sandia are subject to a federal background investigation to meet the requirements for access to classified information or matter if the duties of the position require a DOE security clearance. Substance abuse or illegal drug use, falsification of information, criminal activity, serious misconduct or other indicators of untrustworthiness can cause a clearance to be denied or terminated by DOE, resulting in the inability to perform the duties assigned and subsequent termination of employment.

EEO Statement:

All qualified applicants will receive consideration for employment without regard to race, color, religion, sex, sexual orientation, gender identity, national origin, disability, or veteran status.
