Physicist

Description

The Red Gate Group is seeking a talented and motivated Physicist to support advanced multiphysics modeling and simulation efforts in Ft. Belvoir, VA. In this role, you will contribute to high-impact government contracts focused on conventional weapons effects, computational structural dynamics, computational fluid dynamics, and multi-spectrum functional defeat modeling. The ideal candidate brings a strong physics foundation, hands-on simulation experience, and the ability to operate effectively within a collaborative, fast-paced technical environment supporting national defense priorities.

Key Responsibilities:

• Develop, execute, and validate Computational Structural Dynamics (CSD) and Computational Fluid Dynamics (CFD) models to support conventional weapons effects analysis
• Perform coupled CFD/CSD simulations to characterize complex fluid-structure interaction phenomena under operationally relevant conditions
• Conduct thermal modeling to assess heat transfer, thermal loading, and material response in weapons effects scenarios
• Build and apply multi-spectrum functional defeat models to evaluate target vulnerability and system defeat mechanisms across relevant threat profiles
• Support the development and maintenance of conventional weapons effects models in compliance with program-specific requirements and standards
• Execute rigorous uncertainty analysis to quantify and communicate model fidelity, sensitivity, and confidence bounds to stakeholders
• Collaborate with interdisciplinary teams of physicists, engineers, and analysts to integrate simulation outputs into broader system-level assessments and technical reports

Required Qualifications

Bachelor's degree in Physics, Applied Physics, Mechanical Engineering, or a closely related STEM discipline (Master's preferred)

• 8+ years of experience in multiphysics modeling and simulation, consistent with a journeyman proficiency level
• Demonstrated hands-on experience with CFD and/or CSD modeling tools (e.g., ANSYS, LS-DYNA, ABAQUS, OpenFOAM, AUTODYN, or equivalent)
• Working knowledge of coupled multi-physics simulation methodologies, including fluid-structure interaction
• Familiarity with uncertainty quantification (UQ) methods and their application in physics-based modeling environments
• US Citizen with an Active Top Secret / SCI security clearance (required at time of application)
• Strong written and verbal communication skills with the ability to document and present technical findings clearly to both technical and programmatic audiences

Desired Qualifications

• Experience with conventional munitions, terminal ballistics, or weapons effects modeling in a DoW or DOE-related program environment
• Familiarity with multi-spectrum target defeat analysis or vulnerability/lethality (V/L) assessments
• Experience working within a government contracting environment, including adherence to SOW deliverables, CDRLs, and program schedules
• Proficiency in scripting or programming languages (Python, MATLAB, or Fortran) for pre/post-processing and automation of simulation workflows
