  • Develop algorithms or models to represent complex data sets with constitutive relationships representing dependencies between sub-systems.
  • Develop methods to manage large data sets at different levels of resolution and time scales to simulate systems operations.
  • Apply operations research and/or systems engineering techniques and methodologies to problems of asset/resource management and trade-space studies.
  • Develop system models to represent business or programmatic units, understanding interdependencies.
  • Modeling and simulation work with first principle physics-based hydro-structural codes.

The successful candidate will be required to:
  • Execute high quality modeling and/or simulation research resolving nuclear energy, nuclear weapons, or nuclear security challenges.
  • Participate in a fast-paced work environment and interface between multiple disciplines.
  • Document and/or present advanced technical work clearly and effectively.
