The Post\-Doctoral Appointee Program is designed to recruit outstanding Ph\.D\. applicants to assist a line organization in meeting its mission objectives and to provide a professional technical work environment for the employee\. The Ph\.D\. must have been conferred within one to five years prior to employment\. These assignments are for a one\-year period, with the option at managements discretion to serve no more than five additional one\-year assignments\.



We are seeking a mechanical engineer or materials scientist who has recently earned their Ph\.D\. to collaborate with staff on experimental evaluation of property\-microstructure relationships of additive manufactured \(AM\) metals\. The candidate will contribute to materials processing, microstructural characterization, and mechanical property evaluation of additively manufactured metals\. The individual will be expected to collect, analyze and interpret data from the manufacturing process, state\-of\-the\-art microscopy, and mechanical testing\.



On any given day, the candidate may be called on to:



+ Run experiments involving additive manufacturing of metals

+ Perform microstructural assessment and characterization

+ Use principles of both physical and mechanical metallurgy to develop understanding of the materials

+ Design and develop experimental platforms and test plans to study specific aspects of microstructural evolution during processing and post manufacture

+ 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:



+ A PhD in mechanical engineering or materials science, or a related field

+ A record of first\-author or co\-authored scientific publications in peer\-reviewed journals and presentations at scientific conferences

+ Documented experience with AM processes and familiarity with procedures for defining process parameters and fabricating quality material

+ Documented experience with microstructural characterization of AM austenitic stainless steels using conventional and advanced microstructural techniques including scanning \(transmission\) electron microscopy, and electron backscattered diffraction

+ Experience with operation of servohydraulic mechanical test frames for tensile, fracture, and fatigue testing, demonstrated through publication of such measurements

+ The candidate must be a U\.S\. citizen capable of obtaining a Department of Energy security clearance



Desired:



+ Strong understanding of physical and mechanical metallurgy and knowledge of thermomechanical processing of austenitic stainless steel alloys

+ Familiarity with hydrogen systems and the effects of hydrogen on the behavior of austenitic stainless steels

+ 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

+ Experience with computer programming for automated large dataset analaysis such as in Matlab, Python, or equivalent



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 Sandias 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 Departments work covers a broad range of areas, including analyzing hydrogens 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\.

\*These benefits vary by job classification\.



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\.
