Job Information

Sandia National Laboratories Mechanical Engineer (Experienced) in Livermore, California


We are seeking a Solid Mechanics or Structural Dynamics Engineer (R&D S&E, Mechanical Engineer) to join our collaborative team.

Are you passionate about your work and dream of utilizing state-of-the-art facilities to explore solutions? Do you want to join a dynamic team that solves challenging issues for our nation's security? If so, the Multi-Physic Modeling & Simulation team has an opeing for a highly motivated engineer.

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

  • Conduct solid mechanics and/or structural dynamics research, development, modeling, and simulation to support projects in several areas (e.g. nuclear safety, design, and qualification), for both internal and external customers (e.g., the Department of Defense and Homeland Security)
  • Use state-of-the-art tools to conduct computational simulations (e.g., linear-elastic static; large-deformation plasticity; nonlinear structural dynamics; shock; vibration; hydrodynamics; and coupled thermal-mechanical-electrical)
  • Utilize uncertainty quantification with FEM/FEA to predict component or system behavior under specific operating conditions
  • Build model credibility through the application of verification and validation principles
  • Collaborate with experimental mechanics and material science organizations to provide validated results of complex and challenging problems


  • Master's degree in mechanical, civil, applied engineering, or related discipline plus 1 or more years of relevant experience; or equivalent combination of education and experience
  • Educational background in solid mechanics, structural analysis, or structural dynamics or related
  • Experience with modeling and simulation tools (e.g., the finite-element method); ability to assess tool capabilities and limitations when selecting the appropriate methodology for model development and simulation
  • Ability to obtain and maintain a US DOE Q security clearance


  • Ph.D. in mechanical, civil, applied engineering, or other applicable engineering field
  • Demonstrated ability to present and publish research findings
  • Experience in computational mechanics or code development for engineering sciences applications
  • Programming or scripting experience (e.g., C/C++, Matlab, or Python)
  • Experience with finite-element methods, continuum and noncontinuum mechanics, parallel algorithms, and/or contact mechanics
  • Material-failure modeling experience
  • Demonstrated structural dynamics analysis experience (e.g. component and system level analysis considering steady-state and transient disturbances)
  • Basic familiarity with modern substructure modeling, such as Craig-Bampton substructuring

Department Description:

The Multi-Physics Modeling and Simulation Department at Sandia National Laboratories, California, conducts 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:

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 Statement:

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.
