Radiation Transport Postdoctoral Research Associate | Los Alamos, NM | Los Alamos National Laboratory

Radiation Transport Postdoctoral Research Associate

What You Will Do

Come join the brightest minds at the most innovative R&D facility supporting National Security! The Computational Physics and Methods Group (CCS-2) at Los Alamos National Laboratory is seeking a Transport Methods Postdoc to join our Radiation Transport Team.

There is nothing ordinary about the work being done at LANL, and CCS-2 is no exception. Our ~55 staff, postdocs and students conduct fundamental scientific research and develop computational methods and algorithms across a broad range of physics areas in order to answer questions relevant to LANL's national security mission. The Transport Team in particular provides subject matter expertise and production software products in the areas of linear and nonlinear neutral particle transport (neutrons, gamma rays, thermal X-rays), charged particle transport, and high energy-density physics.

The successful applicant will work on a multidisciplinary team in a collaborative environment developing computational transport models that run on the latest high-performance computers. In collaboration with their future mentor, they will propose a well-defined research plan that will allow them to develop new skills and knowledge and produce computational methods and results that can be published in the scientific literature and presented at technical conferences.

CCS division has a staffing focus area around Diversity, Inclusion, Belonging and Equity. Individuals from underrepresented groups are strongly encouraged to apply.

Directive 206.2 - Employment with Triad requires a favorable decision by NNSA indicating employee is suitable under NNSA Supplemental Directive 206.2. Please note that this requirement applies only to citizens of the United States. Foreign nationals are subject to a similar requirement under DOE Order 142.3A.

Clearance: Selected applicants will be subject to a background investigation conducted by or on behalf of the Federal Government, and must meet eligibility requirements* for access to classified matter. This position requires a Q clearance. and obtaining such clearance requires US Citizenship except in extremely rare circumstances. Dependent upon the position, additional authorization to access classified information may be required, which may or may not be available to dual citizens. Receipt of a Q clearance and additional access authorization ultimately is a decision of the Federal Government and not of Triad.

*Eligibility requirements: To obtain a clearance, an individual must be at least 18 years of age; U.S. citizenship is required except in very limited circumstances. See DOE Order 472.2 for additional information.

New-Employment Drug Test: The Laboratory requires successful applicants to complete a new-employment drug test and maintains a substance abuse policy that includes random drug testing. Although New Mexico and other states have legalized the use of marijuana, use and possession of marijuana remain illegal under federal law. A positive drug test for marijuana will result in termination of employment, even if the use was pre-offer.
