What You Will Do

X-Theoretical Design (XTD) division members are the scientific stewards of the U.S. nuclear stockpile, applying theoretical and computational physics to the performance and safety of nuclear weapons. XTD scientists also contribute their expertise to the nation’s foreign threat assessment, counter-proliferation and non-proliferation efforts through assessment of foreign devices, design of tools to address nuclear emergency response scenarios, and creation of solutions to inhibit nuclear proliferation. In addition, XTD scientists drive cutting edge advances in astrophysics, geophysics, high energy density physics, inertial confinement fusion, chemistry, and material science. Members of XTD use multi-physics codes, running on some of the world’s fastest supercomputers, to create and analyze simulations of very complex systems. We work closely with many other organizations in a diverse variety of tasks, including experimental design and analysis, model development, code validation, and project leadership.

  • Demonstrate thorough knowledge and use of large, multi-physics codes.

  • Apply codes to solve problems of national security interest, exercising personal initiative to guide your own and others’ efforts.

  • Contribute to one or more of the related tasks: leading experimental design and analysis, coordinate with model development efforts, project and/or program leadership, data evaluation, and code validation.

  • Demonstrate leadership through teaming efforts.

  • Contribute to organizational knowledge level by mentoring others.

  • Continue to expand your technical knowledge.

  • Develop/demonstrate generalist capabilities in solving problems.

  • Work with a wide variety of colleagues with varying backgrounds across the laboratory on research covering multiple physics areas in order to solve difficult problems.

  • Demonstrate and maintain excellence in communication, both written and verbal.
