What Your Job Will Be Like

We are seeking a dedicated R&D Computational Physicist staff member to join our dynamic team to support development of computational modeling tools and/or research in measurements and sensor systems. Specific research areas include radiation hydrodynamics in extreme environments, optical emission modeling, supporting optical sensor concept design and development, sensor testing, and related modeling and analysis efforts. Opportunities exist to perform data analysis and exploitation for purposes including but not limited to sensor development and model validation.

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

• Integrate into an established team to perform research and development focused on customer mission requirements from phenomenological understanding to sensor/modeling concept development, design, and analysis in support of these missions.
• Develop, verify, and validate physics-based computational models.
• Apply models and codes to customer-specific problems.
• Work on various systems by performing end-to-end simulations for the evaluation of sensor utility and supporting future sensor designs.

Due to the nature of the work, the selected applicant must be able to work onsite. Minimal travel may be required for this position.

About Our Team

The Phenomenology & Signatures R&D Department (06771) serves national defense and nonproliferation customers with theoretical and computational research of nuclear detonation effects and signatures. We develop first-principles models to underpin a deep physics-based understanding of the development of fireballs and their optical signatures in a variety of circumstances. Department expertise includes radiation transport, hydrodynamics, material behavior and interactions in extreme environments, and code development for high performance computing.

Posting Duration

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.

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

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.
