• Strong understanding of ballistics and/or dynamics.
• Experience with physics-based modeling.
• Familiarity with verification and validation of engineering tools.
• Familiarity with reactive materials, mechanical shock, and/or blast.
• Ability to interpret mathematical expressions representing physical mechanisms and translate knowledge of physics/material science/chemistry into mathematical expressions.
• Ability to find relevant information in available literature sources and apply the information as necessary on projects.
• Proficiency with programming languages such as MATLAB, Python or something similar.
• Experience writing technical reports, publications, and proposals. Comfortable delivering briefings.
• Ability to support multiple projects, adapt to new technical areas, and work effectively in fast paced research settings.
