About Our Team:

Sandia's Resilient Energy and Distributed Systems Integration (REDSI) department conducts research, development and demonstrations of new components and systems that will enable resilient and reliable distributed energy resources as part of a secure and robust electric grid. The department partners extensively with the U.S. industry and other research institutions to pursue high-value solutions that enhance performance, safety, reliability and resilience of energy systems. We establish the technical foundation for advanced models, analysis methods, controls, standards, cyber-security solutions and power electronics concepts applicable to microgrids and interconnected systems. Much of this work is conducted at Sandia's Distributed Energy Technologies Laboratory (DETL), a world-recognized systems integration research facility for over 40 years. This work is sponsored by the U.S. Department of Energy.

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.
