What Your Job Will Be Like: We are seeking a postdoctoral researcher to join our department! You can make an impact to a project involving software development for parallel direct numerical simulation and hybrid direct numerical simulation and large-eddy simulation of turbulent reacting flows coupled with fuel spray, soot formation and oxidation, and thermal radiation over nontrivial geometry on exascale computing platforms. Your work will also involve integrating reduced order surrogate models in the simulation software and performing demonstration runs. You will be working as part of a multi-disciplinary team both within Sandia and with external collaborators. Research success is expected to result in impactful publications in major scientific journals and widespread recognition within the international scientific research community, as well as relevant contributions to the long-term energy and environmental and high performance computing mission objectives of the U.S. Department of Energy. Qualifications We Require: + PhD in engineering, computational sciences, physical sciences, or mathematics + Expertise in high-performance scientific computing + Expertise in high-fidelity simulation of chemically reacting flows Qualifications We Desire: + Expertise in numerical methods for adaptive mesh refinement (AMR) + Experience in programming on graphics processing units (GPUs) + Experience in spray, soot, and radiation modeling + Excellent written and verbal communication skills About Our Team: 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. We also perform numerical research supported by the DOE Vehicle Technology office to improve the understanding of advanced combustion engines.

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. EEO: 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. Position Information: 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.
