What Your Job Will Be Like

We are seeking a R&D S&E, Mechanical Engineer to join our collaborative team environment. As an analyst on our team, you will perform solid mechanics (SM) and/or structural-dynamics (SD) research, development, modeling, and simulation to support a variety of projects (e.g. nuclear safety, design, and qualification, failure, shock and vibration, and/or thermal- mechanical response), and customers (e.g., the Departments of Defense and National Nuclear Security Administration, university collaborations, etc.). Appropriate uncertainty quantification will be used with finite element analysis and other analysis methods to predict component or system behavior under specific operating conditions. Verification and validation of modeling techniques will be used to build model credibility. A SM role will involve detailed predictions of material behavior and failure under a variety of normal and abnormal environments. A SD role requires complex simulations of structural responses to dynamic and shock environments. The analysts in our department work closely with experimental mechanics, code development, and material science organizations to provide validated results of extremely complex and challenging problems that support the design, qualification, and fielding of high consequence engineered systems for national security missions.

On any given day, you may be called on to:

• Build finite element models of components, sub-assemblies, or full systems and use these models to perform non-linear static or dynamic analyses to assess design margins, failure response, design trade studies, fatigue life, system and sub-assembly environments, or provide input to large scale testing for a variety of projects for internal (Sandia) and external customers
• Perform research, development, and simulations and share results through internal reports, journal publications, conferences, and internal design, testing, and qualification reviews
• Use engineering analysis principles and computational methods to support the design, qualification, and fielding of high consequence engineered systems for normal and abnormal environments and combinations of environments (random vibration, shock, blast, impact, crash and burn)
• Apply and develop uncertainty quantification techniques and assess model credibility through the application of verification & validation principles
• Engage with code and model development teams to develop and implement novel models and capabilities for high performance computing algorithms and environments
• Work closely with teams of code/model developers, analysts, and experimentalists to develop and implement novel models and capabilities for high performance computing algorithms and provide validated simulation results for complex and challenging R&D problems
• Collaborate and interact closely with a multi-disciplinary, geographically dispersed team, including engineers and other researchers and analysts across the laboratory at both the California and New Mexico sites

Due to the nature of the work, the selected applicant must be able to work onsite.

Applicants on this requisition may be interviewed by multiple organizations at Sandia National Laboratories.

Salary Range

$139,900 - $280,600

*Salary range is estimated, and actual salary will be determined after consideration of the selected candidate's experience and qualifications, and application of any approved geographic salary differential.

Qualifications We Require

• A Bachelor's degree in a relevant discipline and five (5) years of directly relevant experience, or an equivalent combination of directly relevant education and engineering or scientific experience that demonstrates the knowledge, skills, and ability to perform independent research and development
• Ability to obtain and maintain DOE Q-level security clearance

Qualifications We Desire

The ideal R&D S&E Mechanical Engineer candidate for Sandia National Laboratories will in addition possess the following:

  • working with experimental data and understanding typical structural dynamics testing approaches
  • calibrating models to experimental data and debugging model issues
  • CAD experience
  • running simulations on high-performance computing (HPC) systems
  • integrating AI tools into engineering workflows
• Project leadership experience and the ability to translate customer needs into executable analysis tasks
• Ability to work independently and collaborate well in a multidisciplinary team of designers and test engineers
• Active DOE Q-level or DoW TS security clearance

About Our Team

The Modeling and Simulation (modsim) of Engineering Applications Department at Sandia National Laboratories, California, conducts a wide range of computational simulations, including linear-elastic static; large-deformation, nonlinear structural dynamics; hydrodynamics; solid mechanics; Thermal Fluids; Heat Transfer; and Radiation Transport. To complete these simulations, the department uses and develops a variety of state-of-the-art analytical tools. We partner with Sandia product designers to predict and define environments for the entire design life-cycle. We assist product engineers in optimizing their designs early in a development program and to fully explore the product's performance space during final design qualification. We work closely with experimental experts at Sandia to develop validated models and optimal testing protocols. The department leads and performs modsim and analysis, across these technical disciplines, to directly support nuclear deterrence and other national security engineering applications.

Posting Duration

This posting will be open for application submissions for a minimum of three (3) 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 Q-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 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.
