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.

About Our Team:

Sandia/California's Thermal/Fluid Science and Engineering Department is a multidisciplinary group of engineers and researchers who specialize in fluid mechanics and heat and mass transfer. The work mix in the group includes developing theory and models, performing scientific and high-performance computing, and executing applied engineering analysis for a range of experiments and mechanical designs. The group plays two primary roles in science-based engineering at Sandia: (1) developing new computational methods, capabilities, and tools to describe fluid mechanics and heat transfer; (2) performing computational analysis to predict the design performance of engineered systems in defense, energy, and industry applications. Recent activities within the group include heat transfer modeling, porous media reacting flow modeling, multi-phase flow modeling, battery modeling, hydrogen storage and safety technology, fluid dynamics modeling, combustion and heat transfer modeling, turbulent heat transfer simulation, and applied uncertainty quantification to all of these application areas.

Sandia/California's Mechanics of Materials Department performs experimental and analytical studies to understand the mechanical behavior of materials. Our work consists of both experimental efforts covering the entire discovery-characterization-validation spectrum and the development of models to simulate material responses under various loading and environmental conditions, at scales from atomic to continuum. In addition, computational methodologies are developed to allow implementation of the material models for high performance computing simulations. A current focus of the department is in the area of predicting material failure at various length scales.

Sandia/California's Multi-Physics Modeling and Simulation Department and Modeling and Simulation of Engineering Applications Department both conduct a wide range of computational simulations, including linear-elastic static; large-deformation, nonlinear structural dynamics; hydrodynamics; and solid mechanics. To complete these simulations, the department uses a variety of state-of-the-art analytical tools. Typical departmental programs include the following: detailed structural and thermal analyses of weapon systems; analysis-based design guidance for weapon components; the development of forging and welding modeling capabilities; pressure vessel analyses, including aging and failure; hydrodynamics modeling and simulations; and failure model development and implementation (metals and composites). In addition, a current major departmental focus is the development of science-based failure models and mesh-convergent numerical methodologies.

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.
