Model Validation Intern Jobs (NOW HIRING)

What Your Job Will Be Like
The Nonlinear Mechanics and Dynamics (NOMAD) Research Institute is an 8-week long program that brings together researchers from around the world to work on challenging research problems in engineering sciences. The Component Science and Mechanics Department is seeking motivated and productive student interns to contribute to a number of summer research projects. The internship will provide you with opportunities to work in diverse research teams, to participate in a research project that will be presented at a final seminar series, and to engage/network with professionals working within their research fields. The teams generally consist of 3 interns and 3-5 mentors per project team.
Past summer projects from 2026 include:

• Breaking Bats: Designing a Collapsable Baseball Bat Using Topology Optimization
• Chaotic Vibration Response of Nonlinear Components under Forced Vibration
• Implementing Multi-Input-Multi-Output Shock Capabilities
• Predicting Printability of Particle-laden Inks
• Multiscale Modeling of the Mechanical Response of Tantalum Alloys
• Experimental Characterization of Gas Transport in a Vibrated Multiphase System

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.
