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.
We are seeking a R&D Mechanical Engineer to join our collaborative team as a Structural Dynamics Analyst!
On any given day, you may be called on to:
Perform structural dynamics research, development, modeling, and simulation to support a variety of projects (e.g. nuclear safety, design, and qualification), and 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; nonlinear structural dynamics; shock; vibration; coupled thermal-mechanical)
Utilize uncertainty quantification techniques with FEM/FEA to predict component or system behavior under specific operating conditions
Build model credibility through the application of verification and validation principles
Work closely with experimental mechanics and material science organizations to provide validated results of complex and challenging problems
Master's degree in mechanical engineering or other applicable engineering field plus 1 or more years of experience; or equivalent
Educational background in solid mechanics, structural analysis, or structural dynamics
Demonstrated structural dynamics analysis experience (e.g. component and system level analysis considering steady-state and transient disturbances)
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 hold a DOE Q security clearance
Ph.D. degree in mechanical engineering or other applicable engineering field
Proven ability to interact with test engineers (e.g., support test design with modeling/simulation, correlate dynamic test data to structural dynamics simulation predictions)
Basic familiarity with modern substructure modeling, such as Craig-Bampton substructuring
Demonstrated programming/scripting experience with Matlab or Python
Proven ability to document and present findings
Existing US DOE Q security clearance
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.

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.
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.
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.
