Postdoctoral Appointee in Modeling and Simulation of Thermal Protection Systems for Hypersonic Reentry Vehicles

Albuquerque, NM 87102


Posting Duration:



This posting will be open for application submissions for a minimum of seven (7) calendar days, including the ‘posting date’. Sandia reserves the right to extend the posting date at any time.



Salary Range:







*Salary range is estimated, and actual salary will be determined after consideration of the selected candidate's experience and qualifications, and application of any approved geographic salary differential.



What Your Job Will Be Like:





You could be the postdoctoral appointee we are seeking to partner with a dedicated team performing modeling and simulation research for the development of thermal protection systems (TPS) for hypersonic reentry vehicles. We are developing mesoscale and macroscale models that couple multiple physics across length scales to predict the performance and degradation of composite heat shield materials in hypersonic flight environments. You will develop and implement these models on Sandia’s extensive high-performance computing assets using innovative multi-physics simulation codes. We also desire to combine high-fidelity simulation with experimental data and machine learning techniques to develop the best integrated solution for our national security. You will demonstrate proficiencies and interest in research spanning multiple fields, including heat transport, multi-material mechanical deformation, composite materials, microscale/mesoscale modeling, chemistry, and fluid dynamics.



On any given day, you may be called on to:





+ Develop mathematical models for coupled fluid, thermal, chemical, radiative, and mechanical physics in composite materials or in component systems at the meso- and/or macro-scales



+ Perform large-scale computational analyses to answer scientific and engineering questions supporting hypersonic heat shield material development



+ Combine physics simulations with experimental data and machine learning techniques to deliver solutions to national security problems



+ Work efficiently and independently under the supervision of a senior Sandia technical staff member



+ Interact within a dynamic team of experimental and computational scientists and engineers to develop this mission critical TPS technology



+ Publish work in peer-reviewed scientific publications and in internal technical reports



+ Present work to team members, customers, and the larger scientific community





Join our team and achieve your goals while making a difference!





Qualifications We Require:





+ You have, or are pursuing a Ph.D. in Chemical Engineering, Mechanical Engineering, Materials Science/Engineering, Chemistry, Physics, or other related engineering or natural science field and will have completed your Ph.D. prior to starting at Sandia



+ Experience in computational modeling and simulation with coupling of various physical domains such as thermal, mechanical, chemical, and/or fluid physics



+ Experience with high-level programming or scripting languages, such as Python or C+

+ + Ability to acquire and maintain a DOE Q security clearance





Qualifications We Desire:



Ideally, your background could also include:





+ Experience with the Linux operating system



+ Experience in composite materials modeling



+ Experience in material science, materials processing, or materials manufacture including familiarity with composite, porous, or complex materials



+ Experience in bringing together materials processing, modeling, and experimental methods to improve material properties



+ Experience developing gas-surface interaction or surface chemistry models



+ Experience with advanced simulation techniques (FEM/FEA, CFD, etc.) on massively parallel computing clusters



+ Python development experience



+ Experience with object-oriented programming in C++ within an existing, large code base



+ Experience with version control systems (e.g. Git, CVS, etc.)



+ Proven track record of publications and innovation, as evidenced by peer-reviewed journals and external presentations at scientific conferences

Security Clearance:







Position requires a Department of Energy (DOE) L security clearance to start, or equivalent active security clearance with another U.S. government agency (e.g., DOD).



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 need to be able to maintain a DOE L-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.



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.
