Posted: April 13, 2019

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. : We are seeking a mechanical engineer or materials scientist who has recently earned their Ph.D. to collaborate with a dynamic community of senior researchers engaged in developing a comprehensive understanding of hydrogen-assisted fracture in austenitic stainless steels, aluminum alloys and their welds for integration into advanced computational tools to predict aging in hydrogen and hydrogen isotope environments. On any given day, you may be called on to: + Design and execute mechanical experiments to probe hydrogen-deformation interactions 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 manufacturing + Contribute to fracture studies in extreme environmental conditions (such as high-pressure hydrogen and subambient temperature), individually and collaboration with staff + Use principles of both physical and mechanical metallurgy to develop understanding of the materials, their microstructures and fracture performance + 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

Required:
You have the following: + A PhD in materials science, 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 + Ability to obtain and maintain a Department of Energy Q-level security clearance

Desired:
+ Documented experience with microstructural characterization of structural steels and/or aluminum alloys using conventional and advanced microstructural techniques including scanning (transmission) electron microscopy, and electron backscattered diffraction + Deep understanding of physical and mechanical metallurgy and knowledge of thermomechanical processing of austenitic stainless steel alloys and aluminum alloys + Familiarity with hydrogen systems and the effects of hydrogen on the behavior of austenitic stainless steels and aluminum alloys + Experience with light sources and neutron diffraction to evaluate residual stresses and microstructural characterization + Design of experiments (including safety planning) + Demonstrated innovation – from planning to delivery of results + Collaborative work habits – ability to efficiently leverage available expertise + Inclusive research approach - ability to work with a diverse group of scientists and engineers + Good communication skills

Department Description:

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.

Security Clearance:

Position requires a Department of Energy (DOE) granted Q-level security clearance. Sandia is required by DOE directive to conduct a pre-employment drug testing, and a pre-employment background review that includes personal reference checks, law enforcement record and credit checks, and employment and education verifications. Applicants for employment must be able to obtain and maintain a DOE Q-level security clearance, which requires U.S. citizenship. 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, rendering the inability to perform the duties assigned and resulting in termination of employment.
