Postdoctoral Appointee

Sandia National Laboratories

Albuquerque, NM

Job posting number: #7069934 (Ref:673296)

Posted: September 16, 2020

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 influencing the future of organic materials and optimizing their performance? Join a diverse team that solves significant issues for our nation’s security! We are seeking a Postdoctoral Appointeeto join our team conducting research related to coupled physics in complex, multiphase fluid flow. You should have a strong background in solving coupled multi-physics problems especially multiphase fluid dynamics, and transport. Knowledge in the areas of electromagnetics, thermal and species transport, or complex rheology would be beneficial. Under the guidance of members of the technical staff, you will develop advanced computational models for numerical simulation of coupled problems involving free surface flows and complex rheology. On any given day, you may be called on to: + Develop, implement and improve numerical computational models for simulating coupled physics problems. These may include Maxwell’s equations coupled to thermal transport for passive cooling films or involve fluid mechanics, energy transport, and chemical reaction processes for foam filling. + Develop and apply models to characterize extrusion flows of particle-filled polymers for direct ink write applications. Work on implementation of Elastoviscoplastic models with novel algorithms. + Conduct research to validate models, present, and publish results.

Required:
+ Ph.D. in Engineering, Computer Science, Applied Math, or related field + Experience with computational modeling of fluids and using the Linux operating system + Demonstrated record of peer-reviewed publications and presentation or work at appropriate scientific conferences + Ability to obtain and hold a DOE L security clearance

Desired:
+ Demonstrated ability to solve complex engineering problems including microscale physics + Clear, effective communication skills -- oral and written + Demonstrated ability to work effectively in large, multi-disciplinary teams. + Familiarity with standard programming languages including C, C++, and numerical analysis packages, such as Matlab + Experience using and/or writing scientific finite element codes + Experience in modeling multiphase transport, materials science, and chemical processes, particularly in the area of chemical reactions and thermodynamics + Demonstrated ability to prepare and present briefings to technical peers as well as program and line management (internal and external) + Ability to work towards a constantly changing target, with intermittent sprints and hard deadlines + Travel 2-4 times per year to participate in program meetings

Department Description:

The Fluid and Reactive Processes department is responsible for conducting research on coupled transport phenomena (mass, momentum, energy, etc.) for processes that span multiple length and time scales (nano ->meso ->macroscale) in support of internal and external customers. This research is applied tothe flow of and within disordered, multiphase or heterogeneous materials (e..g.,complex and reacting fluids, powders and particulate materials, and energetic materials) for assessing production, safety and performance of weapon components. This research is used to develop validated numerical predictive tools that we apply to DOE, DOD, and industrial customer problems. Our work spans fundamental research and development to engineering analysis of applied problems. Our basic research activities focus on developing the scientific insights and physical models that will enhance our predictive simulation capabilities. Application projects range from small modeling efforts requiring rapid and agile turnaround to high consequence applications with an emphasis on credibility of model results by exercising and advancing sound V&V/UQ practices. We work closely with experimentalists and code developers to improve the fidelity of supporting tests and to ensure needed code functionality is available.

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 need to be able to obtain and 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 the DOE, resulting in the inability to perform the duties assigned and subsequent termination of employment.
