What Your Job Will Be Like:
We are seeking a computational scientist to conduct innovative research and analysis of radiation transport and/or induced effects in materials and components. You will develop and perform modeling, simulation, and analysis of electron, X-ray, gamma-ray, and neutron radiation transport for Sandia’s nuclear deterrence and other missions. Your work will help define environmental specifications for our nuclear deterrence systems and components and predicting their reliability in various radiation environments. You will also apply techniques for verification, validation, and uncertainty quantification (VVUQ) to assess the credibility of the simulation and analysis results you deliver. You will work in a collaborative environment with a diverse team and have access to some of the world’s most powerful computing tools.
On any given day, you may be called on to:
Perform high performance computing-based simulations and analyze data to predict the transport of radiation and assess its effects on system and component design and qualification
Conduct fundamental research and development around radiation physics and effects on materials to provide solutions for next generation problems
Use and/or develop radiation transport codes to model the interaction of particle radiation (X-rays, electrons, neutrons, and gamma-rays) with matter
Present results at workshops, conferences, and meetings with sponsors and partners
The Nuclear Deterrence Materials and Radiation Effects department is committed to attracting, retaining, and cultivating an outstanding workforce representing a broad group of people and perspectives. This hardworking team works together to accomplish extraordinary results. The job title for this position will be R&D S&E, Physics.
Qualifications We Require:
Master’s degree in Physics, Nuclear Engineering, Computational Science, or a related STEM field plus one year of directly related experience that demonstrates the knowledge, skills, and ability to perform independent research and development; 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 US DOE Q-level security clearance
Qualifications We Desire:
PhD in Physics, Nuclear Engineering, Computational Science, or a related field
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)
Experience in the use of Python and other scripting languages for post-processing analyses
Experience in simulation code development using languages such C++
Publication of research results in peer reviewed journals
Proven ability to work both independently and in a multidisciplinary team environment
Strong interpersonal and communication skills
About Our Team:
The Nuclear Deterrence Materials and Radiation Effects department provides 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.
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.
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.
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.
