- Sandia National Laboratories
- Location: Livermore, CA
- Job Number: 7062536 (Ref #: 670182)
- Posting Date: Nov 27, 2019
Job DescriptionThis 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. : We are seeking a mechanical engineer, civil engineer, metallurgical engineer, materials scientist or similar who has recently earned their Ph.D.to collaborate with a diverse community of senior researchers engaged in developing a comprehensive understanding of fatigue, fracture and failure of structural materials, such as steel and aluminum alloys and their welds. This scope includes how fracture and damage processes in materials change upon exposure to environments such as hydrogen, hydrogen isotopes, sub-ambient temperature and moisture. On any given day, the candidate may be called on to: + Design and execute mechanical experiments to probe environment-deformation interactions as well as fatigue and fracture processes in complex microstructures in metal alloys + Develop experimental platforms and test plans to study specific aspects of microstructural evolution and performance during deformation, including manufacturing processes + Use principles of both physical and mechanical metallurgy to develop understanding of the materials, their microstructures and their deformation and fracture behavior + Perform microstructural assessment and characterization using electron microscopy tools, individually and in collaboration with staff + Communicate your findings to colleagues, customers and the larger scientific community through presentations, technical reports and articles suitable for publication in high-impact journals
+ A PhD in materials science, metallurgical or mechanical engineering, or a related field + Experience with fatigue and/or fracture of metals and metal alloys + Experience with servohydraulic mechanical test frames for tensile, fracture, and fatigue testing + A record of first-author or co-authored scientific publications in the above areas within peer-reviewed journals and presentations at scientific conferences
+ Documented experience with microstructural characterization of structural steels and/or aluminum alloys using conventional and advanced microscopy and microanalysis techniques + Strong understanding of physical and mechanical metallurgy and knowledge of thermomechanical processing of steels and aluminum alloys + Familiarity with the effects of hydrogen on the behavior of structural materials: ferritic and austenitic steels and aluminum alloys + Experience with light sources and neutron diffraction to evaluate residual stress and microstructure + Design of experiments (including safety planning) + Collaborative work habits– ability to efficiently leverage available expertise + Inclusive research approach - ability to work with a diverse group of scientists and engineers + Excellent communication skills
The Hydrogen and Materials Science Department provides expertise to both Sandia and the Nation on the interaction of hydrogen (and its isotopes) with all types of materials. The Department performs scientific and engineering research to develop fundamental understanding on the aging of materials in gaseous environments, including hydrogen, and applies this understanding to determine its effects on the performance and reliability of materials relevant to Sandia’s nuclear weapons and energy missions. Department staff conducts research and development primarily for two important customers: 1) Gas Transfer Systems (GTS) for the Nation's Nuclear Weapons Enterprise; and 2) the Fuel Cell Technologies Office (FCTO), part of DOE's Office of Energy Efficiency and Renewable Energy. The Department’s work covers a broad range of areas, including analyzing hydrogen’s long-term impact on materials used in fuel cell and gas transfer systems, developing solar thermochemical technology for hydrogen production, assessing the suitability of materials for hydrogen storage, advising hydrogen safety codes and standards, maintaining and enhancing nationally recognized core and enabling capabilities in hydrogen science, and initiating hydrogen storage and fuel cell market transformation strategies to bring technological advancements towards broad-based commercial availability.

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 need to 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 clearance, a pre-processing background review may be conducted prior to a required federal background investigation. Applicants for a DOE security clearance need to 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. Members of the workforce (MOWs) hired at Sandia who require uncleared access for greater than 179 days during their employment, are required to go through the Uncleared Personal Identity Verification (UPIV) process. Access includes physical and/or cyber (logical) access, as well as remote access to any NNSA information technology (IT) systems. UPIV requirements are not applicable to individuals who require a DOE personnel security clearance for the performance of their SNL employment or to foreign nationals. The UPIV process will include the completion of a USAccess Enrollment, SF-85 (Questionnaire for Non-Sensitive Positions) and OF-306 (Declaration of for Federal Employment). An unfavorable UPIV determination will result in immediate retrieval of the SNL issued badge, removal of cyber (logical) access and/or removal from SNL subcontract. All MOWs may appeal the unfavorable UPIV determination to DOE/NNSA immediately. If the appeal is unsuccessful, the MOW may try to go through the UPIV process one year after the decision date.
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.
