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.

$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.

• A Bachelor's degree in a relevant discipline and five (5) years of directly relevant experience, or an equivalent combination of directly relevant education and engineering or scientific experience that demonstrates the knowledge, skills, and ability to perform independent research and development.
• Ability to obtain and maintain a DOE Q security clearance

The ideal R&D S&E Computer Scientist candidate will in addition possess the following:

• Graduate degree in Computer Science or a highly related field where an independent research project was a graduation requirement (e.g., independent project, thesis, or dissertation).
• Demonstrated software development skills and familiarity with modern software development practices and tools (e.g., Agile).
• Strong verbal and written communication skills, ability to work effectively in multidisciplinary teams, and a passion to improve and expand technical skills.

Also, for this posting we are seeking candidates with the following experience:

• PhD in Computational Science, Engineering, Physics, Applied Math, or a related STEM field
• Experience with computational modeling and simulation of radiation transport/effects and/or multi‑physics applications
• Publication of research results in peer reviewed journals
• Experience with the development, code implementation and/or application/analyses of…
