What Your Job Will Be Like

We are seeking a Computational Scientist to develop and execute modeling & simulation of electron, X-ray, and gamma-ray radiation transport for Sandia's nuclear deterrence and other missions! You will help define environmental specifications for our nuclear deterrence systems and components and predict the reliability of our engineered technologies in various radiation environment scenarios. You will model the impacts of radiation effects on materials and/or electronics used within these technologies, helping to inform design decisions for adequate component function and resilience.

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

• Implement new features and algorithms or improve existing functionality while maintaining code quality to advance our radiation transport codes.
• Develop models and perform simulations on world-class high-performance computing systems to predict the transport of radiation and its effects on system and component design and qualification.
• Perform fundamental research and development around radiation physics and effects on materials to provide solutions for next-generation problems.
• Identify new research ideas and directions, collaborating with colleagues to write research proposals.
• Present results at workshops, conferences, and meetings with sponsors and partners.

Due to the nature of the work, the selected applicant must be able to work onsite. Relocation will be provided for those that qualify.

Salary Range

$117,500 - $235,700

*Salary range is estimated, and actual salary will be determined after consideration of the selected candidate's experience and qualifications, and application of any approved geographic salary differential.

• Experience working in a SCRUM team

About Our Team

The Radiation Software Department (1321) performs theoretical and computational research to understand the effects caused by ionizing radiation from nuclear weapons, space environments and other sources, including those generated by experimental facilities. We develop physical models and numerical methods for deployment in computer codes that model the interaction of particle radiation (X-rays, electrons, neutrons, gammas) with matter. We use these and other types of codes to predict and understand electrical and mechanical radiation effects. Software quality engineering, software verification methods, validation to experimental data, and uncertainty quantification are fundamental to these computational efforts. We support a variety of customers who are concerned with the effect of radiation on their systems and components.

The team is committed to attracting, retaining, and encouraging an outstanding workforce representing a broad group of people and perspectives. We share this common vision by encouraging mutual respect among staff, post-docs, and interns. This hardworking team works across Sandia National Laboratories to accomplish outstanding results.

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.
