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 need to be able to obtain and maintain a DOE L-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 the DOE, resulting in the inability to perform the duties assigned and subsequent termination of employment.
All qualified applicants will receive consideration for employment without regard to race, color, religion, sex, sexual orientation, gender identity, national origin, age, disability, or veteran status and any other protected class under state or federal law. : This postdoctoral position is a temporary position for up to one year, which may be renewed at Sandia's discretion up to five additional years. The PhD must have been conferred within five years prior to employment. Individuals in postdoctoral positions may bid on regular Sandia positions as internal candidates, and in some cases may be converted to regular career positions during their term if warranted by ongoing operational needs, continuing availability of funds, and satisfactory job performance.
The Diagnostic Science and Engineering Department (01512) develops and applies diagnostics for engineering sciences applications. We develop the expertise needed to adapt measurement techniques to challenging environments and understand the additional uncertainty which may be introduced. For model validation, we work in tandem with modelers to design optimum experiments. We assist data users in interpreting and understanding experimental results. Finally, we apply our expertise to understand the limitations of any diagnostic and the experimental uncertainty of the resulting data. The department is engaged in experimental activities in fluid mechanics, multiphase and reactive flows, rheology, shock science, and the thermal, chemical and mechanical characterization of materials, including polymeric and energetic materials. Our efforts are focused on (1) development and application of advanced diagnostics, (2) conduct of fundamental experiments to unravel unresolved phenomenology and to characterize material properties and material response, (3) design and performance of validation experiments supporting the Center's code development efforts, and (4) experimental support for weapon qualification/certification. The department has responsibility for the operation of thermal/fluids laboratories, pilot-scale multiphase flow test-beds, full-field measurement of material response and material characterization, and rheological characterization facilities. Recent post-doctoral researchers in our group have gone on to faculty positions at research universities and staff positions at national laboratories. Our primary mission supports U.S. Department of Energy Defense Programs, as well as projects funded through the U.S. Department of Defense, NASA, and industry.
