Job Description

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 solves significant issues for our nation's security? We are seeing a Postdoctoral Researcher (Postdoctoral Appointee) to work with our team to develop physics-based models and novel computational methods for the simulation of complex multiphase flows with phase change. On any given day, you may be called on to: + Direct the implementation of new sub-models in a Sandia research code and in commercial multi-physics software, analyze the results and work closely with experimentalists to validate these models. + Deploy and carry out simulations on the Labs' super-computers (due to the massively parallel requirements imposed by the problem scale). + Explore the feasibility of multiphase simulations on novel computer architectures.

+ Ph.D., conferred within 5 years prior to employment, in aerospace, mechanical, material science, computer science, applied mathematics, or a closely related field + Knowledge of multiphase flow (liquid-gas systems) and turbulence; + Familiarity with numerical methods used in computational fluid dynamics; + Working knowledge of programming languages (in particular, Fortran and C++); + Experience with reading and interpreting third-party computer code.

+ Expertise in numerical techniques for heat transfer and phase change modeling. + Previous experience in parallel computing.

Department Description:

Sandia/California's Thermal/Fluid Science and Engineering Department is a multidisciplinary group of engineers and researchers who specialize in fluid mechanics and heat and mass transfer. The work mix in the group includes developing theory and models, performing scientific and high-performance computing, and executing applied engineering analysis for a range of experiments and mechanical designs. The group plays two primary roles in science-based engineering at Sandia: (1) developing new computational methods, capabilities and tools to describe fluid mechanics and heat transfer; (2) performing computational analysis to predict the design performance of engineered systems in defense, energy, and industry applications. Recent activities within the group include heat transfer modeling, porous media reacting flow modeling, multi-phase flow modeling, battery modeling, hydrogen storage and safety technology, fluid dynamics modeling, combustion and heat transfer modeling, turbulent heat transfer simulation, and applied uncertainty quantification to all of these application areas.

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.

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.
