We have openings for Computational Physicists to pursue challenges relevant to national security in the development of multi-physics simulation codes. Under consultative direction you will collaborate as part of an interdisciplinary code development team in advancing the state of the art in large-scale multi-physics simulation. The national security mission involves developing simulation capabilities for Stockpile Stewardship, nuclear counter-terrorism, conventional weapons, and high energy density physics experiments. The code development focus is on models and algorithms for use in high-performance computing on the latest large-scale parallel computing platforms. You will act as a scientific/technical leader as part of large projects/programs, contribute
