What Your Job Will Be Like:

The Hydrogen and Materials Science Department (8367) is seeking a postdoctoral appointee to collaborate with a diverse community of researchers in the Hydrogen Effects on Materials Laboratory (HEML). The HEML team develops comprehensive understanding of fatigue, fracture and failure of structural materials. Our research emphasizes experimental studies of the interactions of gas-phase hydrogen and hydrogen isotopes with structural metals and welds, using unique, custom facilities for performing experiments in high pressure gaseous environments. The research is performed in large teams that include daily interactions with microscopists, surface scientists and computational scientists, all operating at multiple length scales. Our research activities have high-visibility both nationally and internationally, thus successful candidates need strong presentation and writing skills.

Due to the nature of the work, the selected candidate must be able to work onsite at the Sandia, Livermore location.

Qualifications We Require:

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

·Experience with fatigue and/or fracture of metals and metal alloys

·A record of first-author or co-authored scientific publications

Qualifications We Desire:

·Experience with servo-hydraulic mechanical test frames for tensile, fracture, and fatigue testing

·Documented experience with microstructural characterization of structural metals 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

·Ability to work with and leverage expertise in a diverse group of scientists and engineers

·Excellent communication skills

About Our Team:

The Hydrogen and Materials Science Department provides expertise to both Sandia and the Nation to advance the infrastructure necessary to promote the use of hydrogen and its isotopes in areas relevant to Sandia's energy and nuclear deterrence missions. Research spans fundamental science to engineered materials in nationally recognized experimental facilities for hydrogen science. Focus areas include: fundamental understanding of material structure and behavior with respect to compatibility and aging in gaseous environments, gas behavior for risk analysis, surface-gas phase interactions, science-basis to inform hydrogen safety codes and standards, advanced water splitting materials for hydrogen production, and solid-state and liquid storage for light duty vehicles and stationary applications. This expertise is applied to hydrogen end-use (e.g. air, marine, rail) application feasibility and performance assessments with industry partners.

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.

Security Clearance:

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.

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.

NNSA Requirements for MedPEDs:

If you have a Medical Portable Electronic Device (MedPED), such as a pacemaker, defibrillator, drug-releasing pump, hearing aids, or diagnostic equipment and other equipment for measuring, monitoring, and recording body functions such as heartbeat and brain waves, if employed by Sandia National Laboratories you may be required to comply with NNSA security requirements for MedPEDs.

If you have a MedPED and you are selected for an on-site interview at Sandia National Laboratories, there may be additional steps necessary to ensure compliance with NNSA security requirements prior to the interview date.

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.
