- Sandia National Laboratories
- Location: Livermore, CA
- Job Number: 7065117 (Ref #: 671452)
- Posting Date: Mar 5, 2020
Job DescriptionThis 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. : We are seeking a Postdoctoral Appointee to work under the guidance of Dr. Habib Najm at Sandia National Laboratories (SNL) in Livermore, California. We are looking for creative problem solvers with fundamental knowledge in uncertainty quantification (UQ), and experience in scientific computing, evidenced by publication and codes. The project at hand involves the development and use of advanced UQ methods and software for global sensitivity analysis, surrogate construction, and forward/inverse UQ in high dimensional systems, targeting coupled multi-physics computational codes for cluster dynamics and fusion plasma modeling. Planned UQ developments include the use of low rank sparse tensor methods, basis adaptation, and multilevel-multifidelity methods, in a practical setting employing large-scale scientific codes. The work will involve extensive interaction with a large and diverse project team, and hands-on use of existing suites of large-scale simulation codes on high-end computational platforms.
+ PhD in the physical sciences, applied mathematics, or engineering + Knowledge and expertise in uncertainty quantification + Knowledge and expertise in computational science and software development
+ Knowledge of multilevel multifidelity and low rank tensor methods + Knowledge and expertise in C++ and Python + Experience in performing collaborative research. + Excellent interpersonal and communication skills.
The Plasma & Reacting Flow Science department at Sandia primarily works on projects funded by the U.S. Department of Energy Office of Science to address needs surrounding both high temperature and low temperature plasma phenomena, combusting flows, reacting gas-solid interfaces, uncertainty quantification (UQ), and related topics such as scientific machine learning. We operate state-of-the-art experimental laboratories, conduct work at the DIII-D tokamak reactor, and utilize both local computer clusters and the DOE Leadership Class supercomputers to conduct massively parallel simulations.

This position does not currently require a Department of Energy (DOE) security clearance. Sandia will conduct a pre-employment drug test and background review that includes checks of personal references, credit, law enforcement records, and employment/education verifications. Furthermore, employees in New Mexico need to pass a U.S. Air Force background screen for access to Kirtland Air Force Base. Substance abuse or illegal drug use, falsification of information, criminal activity, serious misconduct or other indicators of untrustworthiness can cause access to be denied or terminated, resulting in the inability to perform the duties assigned and subsequent termination of employment. If hired without a clearance and it subsequently becomes necessary to obtain and maintain one for the position, or you bid on positions that require a clearance, a pre-processing background review may be conducted prior to a required federal background investigation. Applicants for a DOE security clearance need to be U.S. citizens. 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. Members of the workforce (MOWs) hired at Sandia who require uncleared access for greater than 179 days during their employment, are required to go through the Uncleared Personal Identity Verification (UPIV) process. Access includes physical and/or cyber (logical) access, as well as remote access to any NNSA information technology (IT) systems. UPIV requirements are not applicable to individuals who require a DOE personnel security clearance for the performance of their SNL employment or to foreign nationals. The UPIV process will include the completion of a USAccess Enrollment, SF-85 (Questionnaire for Non-Sensitive Positions) and OF-306 (Declaration of for Federal Employment). An unfavorable UPIV determination will result in immediate retrieval of the SNL issued badge, removal of cyber (logical) access and/or removal from SNL subcontract. All MOWs may appeal the unfavorable UPIV determination to DOE/NNSA immediately. If the appeal is unsuccessful, the MOW may try to go through the UPIV process one year after the decision date.
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.
