We are seeking a Postdoctoral Appointee to support research and development efforts related to compressible flow phenomena. On any given day, you may be called on to: + Research, develop, and apply models of compressible flow phenomena with primary application to aerodynamic characterization of transonic through hypersonic flight vehicles + You will develop and apply methodologies in data-driven turbulence modeling + You will contribute to the development of future, high fidelity, state-of-the-art analysis capabilities for describing the turbulent flowfield over flight vehicle surfaces under a broad range of Mach and Reynolds numbers
+ You have a PhD, conferred within 5 years prior to employment, in the aerospace engineering, mechanical engineering, or a related field (with concentration in fluid dynamics) + You have experience with turbulence modeling (LES, RANS, Hybrid RANS-LES models) for compressible turbulent flows + You bring development experience in CFD for compressible high Reynolds number turbulent flows + Your background includes experience with computational approaches (finite element, finite difference, and finite volume methods) for CFD simulations + You have good communication skills as evidenced by a history of publication of results in peer-reviewed journals and external presentations at appropriate scientific conferences + Ability to obtain and maintain a DoE Q clearance
+ Experience with code development + Experience in numerical simulation of coupled fluid/thermal or fluid/structure interactions + Experience in machine learning methodologies for turbulence model development + Experience with using advanced scientific software (CFD, FEA, etc.) on massively parallel computing clusters + Experience with parallel programming for scientific software applications + Experience with Matlab, scripting languages, and grid generation software + Experience with code and solution verification, validation, and uncertainty quantification + Experience working with a diverse team
The Aerosciences Department offers challenging and important work relating to national security in R&D and technology applications in aerodynamics, aerothermodynamics, compressible fluid mechanics, and flight dynamics. Our primary mission supports U.S. Department of Energy Defense Programs, and aerosciences projects funded through the U.S. Department of Defense, DARPA, NASA, and industry. Our projects span the Mach number range from subsonic through hypersonic and involve systems ranging from aircraft released ordinance to reentry systems and rocket systems. Technical activities include experimental, analytical, and computational efforts plus support of flight test activities, both pre-flight/post-flight analyses and field test operations. The Aerosciences Department maintains a strong balance of research and development activities and works synergistically with other organizations at Sandia to meet current and future customer needs.

Position requires a Department of Energy (DOE) Q-level security clearance. 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 must be able to obtain and maintain a DOE Q-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 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, disability, or veteran status.
