Passionate about your work and dream of utilizing state-of-the-art facilities to deliver solutions? Join a dynamic team and help solve significant issues for our nations' security!

We are seeking a computational physicist to work on mission critical development of electron/X-ray radiation transport codes as well as nuclear deterrent analysis with these codes and ancillary software tools! The radiation transport and cross section processing codes developed and maintained in our department are primarily written in C++ and Fortran. The code development activities require formal software quality and agile practices. Our department performs radiation transport analysis for nuclear deterrents and other applications on a wide variety of projects.

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

+ Implement novel features, developing improved functionality, and maintaining code quality.
+ Use high-performance computing (HPC) platforms to perform large parallel calculations, uncertainty quantification, sensitivity analysis, and parameter studies. This will also include running ancillary support computer codes, some developed in house.


+ A Ph.D. in engineering, physics, computational science, or closely related field
+ Experience with the development and/or applications of either deterministic and/or Monte Carlo methods for particle radiation transport
+ Computer programming experience implementing and or processing of either deterministic and/or Monte Carlo particle radiation transport techniques
+ Ability to obtain and maintain a DOE Q Security Clearance


+ Experience with the development, code implementation and/or application of either deterministic or Monte Carlo methods to coupled electron/X-ray particle radiation transport
+ Experience with uncertainty quantification, verification and validation, sensitivity analysis and/or optimization
+ Experience with high performance computing architectures and execution
+ Scientific computer programming experience with C++ and/or Fortran
+ Experience with Python and Perl scripting languages
+ Experience in software quality practices
+ Experience in working with and/or doing analyses for nuclear deterrent based customer

Department Description:

The Radiation Effects Theory Department (1341) perform theoretical and computational research to understand the effects caused by ionizing radiation from nuclear weapons, space environments and other sources, including those generated by laboratory machines. 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 utilize 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.

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, age, disability, or veteran status and any other protected class under state or federal law.
