Job description

Responsibilities
The physicist will perform scientific analysis and computational modeling to evaluate fratricide, normal, hostile, and intrinsic radiation environments and their effect on the SWS, as well as on personnel. The successful candidate will perform a wide range of tasks spanning radiation transport calculations, Hardening and Vulnerability (H&V) calculations, Electromagnetic Pulse (EMP) calculations, hostile nuclear environment definition, and planning and assessment of radiation/electrical/mechanical testing. Position will require the use of scientific and engineering simulation software, in particular radiation transport codes (e.g., MCNP, Attila, etc.), as well as with object-oriented programming languages (e.g., C++, Python, etc.).
This position will be responsible for the following:
  • Assist the customer in system planning, requirement definition, assessment, and qualification of current and future Navy weapon systems.
  • Develop technical documentation and briefings.
  • Develop and maintain software code as deliverables to the Navy.
  • Develop technical reports capturing assumptions, inputs, outputs, and results.
  • Develop and deliver presentations.
  • Interface directly with the customer.
  • Travel for meetings and customer interactions as required.
  • Contribute to team efforts in the completion of fratricide, normal, hostile, and intrinsic environment studies of applicable systems.
  • Perform radiation transport calculations of free-field and internal dose levels in Navy systems.
  • Perform intrinsic radiation studies for personnel safety.
  • Compare and correlate radiation modeling results with experimental data.
  • Perform Verification & Validation of simulation models and results.
  • Assist in test planning and execution at radiation, electrical, and mechanical above ground test facilities.
  • Work with software engineers to implement physics-based analysis models into maintainable software programs.

Qualifications
Required:
  • Minimum requirement is a BS Degree in Physics or Nuclear Engineering (or other related STEM fields) with 5-7 years of experience; MS with 3-5 years of experience; or PhD with 0-2 years of experience. An advanced degree is preferred and applicants with advanced degrees will be given preference.
  • Must BE ABLE TO OBTAIN and maintain a Top Secret Clearance.
  • Experience in experimental design, execution, and modeling.
  • Experience choosing and applying physical models in the formal analysis of physical systems.
  • Experience in writing technical reports or articles.
