The department has solved materials problems in Nuclear Deterrence (ND) applications ranging from routine material compatibility concerns to manufacturing scale issues. In addition to ND, the department also has a strong record of applying its resources to develop solutions for many challenges including hardening drill bits, lubricating satellite mechanisms, coating hypersonic rails, and developing new applications for 3D printed materials.To address these and other challenges, the department is also heavily active in developing novel and emerging processing and characterization techniques. Current activities include the development of high-throughput and in-situ methods for mechanically testing additively-manufactured (AM) metals, digital image correlation, failure and deformation under complex loading, ductile and brittle fracture mechanisms, and 3D characterization of microstructure and components with destructive serial sectioning and X-ray computed tomography. The department members collaborate heavily across organizations within Sandia in New Mexico and California and manage several multi-million-dollar programs which currently include the Brittle Material Assurance Prediction Program (BritMAPP) and Materials Margins Assurance (MMA). The department's technologists, postdocs, and staff have also been awarded several patents and intellectual property provisions. Our team is committed to nurturing a culture compatible with a broad group of people and perspectives in accordance with the changing makeup of the workforce. In support of this vision, our center actively recruits applicants from diverse groups of backgrounds and fosters an inclusive community. 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:

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. 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 Limited Term Employee (LTE) position is a temporary position for one year term, which may be renewed at Sandia's discretion up to a maximum of seven years. Individuals in LTE 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.
