We share this common vision by encouraging mutual respect among staff, post-docs, and interns from a diverse set of backgrounds. This hardworking team works together to accomplish extraordinary results. Qualifications We Require: + Master’s degree in Physics, Computational Science, Engineering, or related fields, or equivalent combination of relevant education and experience + Experience with computational modeling and simulation of radiation transport and effects + Ability to obtain and maintain a DOE Q-level security clearance Qualifications We Desire: + PhD in Physics, Computational Science, Engineering, or a related field + Experience in performing analyses centered on radiation transport modeling and simulation + Experience with uncertainty quantification, verification & validation, sensitivity analysis, or optimization + Experience with computational modeling and simulation codes such as: finite element, finite difference, finite volume, or particle-in-cell (PIC) + Publication of research results in peer reviewed journals + Proven ability to work autonomously, while integrating effectively into a multidisciplinary team environment + Strong interpersonal and communication skills, with an ability to work alongside a team with diverse backgrounds About Our Team: We are the ND Materials and Rad Effects team! We provide expertise in materials and radiation sciences to support Sandia’s missions in nuclear deterrence, proliferation detection and energy. We steward radiography capabilities and exercise them to image and analyze the structure of materials and components. We develop and characterize organic and inorganic materials used as scintillators in radiation detection technologies. We perform detailed modeling, simulation, and experiments to characterize and analyze the effects of ionizing radiation on materials and components used in our engineered systems. All of this is accomplished by bringing to bear our advanced capabilities and the team’s expertise in materials science, chemistry, physics, computation, and engineering.

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.
