Senior Physicist

Responsibilities The physicist will perform scientific analysis and computational modeling to evaluate intrinsic, normal, hostile, and fratricide 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 object‑oriented programming languages (e.g., C++, Python, etc.). Contribute to team efforts in the completion of intrinsic, normal, hostile, and fratricide 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. Assist the customer in system planning, requirement definition, assessment, and qualification of current and future Navy weapon systems. Develop technical documentation and briefings. 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. Qualifications Minimum requirement is a BS Degree in Physics or Nuclear Engineering with 8‑10years of experience; MS with 6‑8years of experience; or PhD with 3‑5years of experience. 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. Experience presenting results to technical SMEs and government customers of various backgrounds and education levels. Desired Skills A PhD in Physics or Nuclear Engineering. Radiation transport experience (neutron, photon, electron). Ability to create unique code‑to‑code interfaces along with post‑processing routines for model response analyses. Ability to lead a team of motivated and highly skilled engineers and scientists. Experience with industry‑leading verification and validation practices, model uncertainty quantification, industry standard design of experiment processes, and application of statistical analysis of experimental data. Experience with any of the following computational tools: MCNP, Attila, C++, Fortran, or Python. Strong written and verbal communication skills. Demonstrated ability to take initiative and manage detailed tasks. Comfortable working independently or on a team. Knowledge of object‑oriented design. Experience with strategic weapon systems.
