Department Description:

The Component Science and Mechanics Department conducts frontier mechanics research and science-based engineering solutions for component development and assessment. Focus areas for the department include interfacial and micro/nano-mechanics, probabilistic mechanics and uncertainty quantification, and mechanical aspects of component and subsystem reliability. Areas of active interest include: interconnects and encapsulation, fatigue and fracture, energy dissipation at contacts, micro-structural mechanics, shock and vibration, crack initiation and propagation, micro-scale diagnostics, and adaptive structures. Computational and physical simulations, including solid mechanics and structural dynamics for both linear and non-linear systems, are utilized in a dynamic multidisciplinary teaming environment.

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, disability, or veteran status.
