Job Description

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. : **Are you passionate about your work and dream of utilizing state-of-the-art facilities to explore solutions? Do you want to join a dynamic team that helps tackle some of the most challenging issues facing our nation’s security?** We seek to hire a postdoctoral researcher who will perform hybrid direct numerical simulation and large-eddy simulation of turbulent reacting flows relevant to gasoline and natural gas direct injection engines towards the development of predictive turbulence-chemistry interaction models for ignition, flame propagation, knock, and soot films near walls. Research success should 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. On any given day, you will: + Set up and perform DNS simulations that couple complex chemistry with fuel spray, soot formation, and thermal radiation over nontrivial geometry on exascale computing platforms using existing adaptive mesh refinement codes. + Be working as part of a simulation and modeling team both within Sandia and with external collaborators as well with experimental engineer researchers at Sandia.

Required:

You have the following: + PhD in engineering, computational sciences, physical sciences, or mathematics, with expertise in high-fidelity simulation of turbulent combustion and high-performance scientific computing.

Desired:

You also have one, or more, of the following: + Strong verbal and written communication skills are also required. + Strong background in turbulence, combustion, chemical kinetics, engine physics, numerical algorithms, and computational science.

Department Description:

Experimental and computational modeling studies of reacting flow phenomena relevant to combustion processes.

Security Clearance:

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 must 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 DOE security clearance, a pre-processing background review that includes checks of personal references, credit, law enforcement records, and employment/education verifications may be conducted prior to a required federal background investigation. Applicants for a DOE security clearance must 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.
