We have an opening in the Nuclear Security Physics Group for a Theoretical Physicist to work on developing new nuclear diagnostic capabilities and on problems related to the statistical theory of fission chains. This work will support the nation's ability to counter, respond to, and if necessary, mitigate a nuclear or radiological incident quickly. This critical mission is the responsibility of the U.S. Department of Energy, National Nuclear Security Administration's (DOE/NNSA) JTOT (Joint Technical Operation Team) Program--an agile, task-organized unit, ready to react at a moment's notice to support nuclear and radiological weapons of mass destruction incidents.

This position will be filled at either level based on knowledge and related experience as assessed by the hiring team. Additional job responsibilities (outlined below) will be assigned if hired at the higher level.

In this role you will

• Develop theories and mathematical models to predict results of a radiation measurement of a nuclear weapon.
• Lead research in identifying and developing possible new diagnostic methods.
• Use nuclear data and the results of simulations made with radiation transport codes (e.g. MCNP or GEANT4) to unravel the details of a measurement.
• Prepare proposals for agencies that fund research in this mission space
• Work as part of an interdisciplinary team with experimental physicists, computational physicists, and statisticians to reconcile measurements with theories and to refine the theories, hardware, and measurements.
• Lead technical efforts with responsibility for budgets, schedules, deliverables, and resource allocation
• Document and publish research results in peer-reviewed scientific publications and present results at external conferences, seminars and/or technical meetings
• Perform other duties as assigned.

Additional job responsibilities, at the SES.4 level

• Determine project scope, schedule and budget and lead a team of multidisciplinary personnel who conduct analysis under your direct supervision.
• Propose and execute development plans to meet medium/long term objectives in the nuclear diagnostics domain.
• Manage multi-disciplinary teams of scientists and technical personnel.
