  • Use creative problem solving to develop models of military systems to use in simulations to determine the operational effectiveness of both existing systems and novel concepts

  • Perform operational analysis, mission effectiveness analysis, and optimization on conceptual and developmental phase advanced weapons initiatives

  • Model operational environments, perform trade studies via AFSIM, ESAMS, TMAP and other computer simulations

  • Provide technical guidance to engineering development of weapon systems based on simulation results

  • Develop graphical user interfaces and visualization tools

  • Communicate to both technical and non-technical audiences the real-world implications of design requirements

  • Investigate and model advanced radars, comms, sensors, missiles, and aircraft

This role includes, but is not limited to, the following activities:

  • Perform modeling, simulation, and analysis tasks assessing system survivability,

  • System effectiveness, and overall system performance in campaign / engagement / mission-level scenarios.

  • Perform trade studies and simulation analyses with the objective of enhancing and optimizing system performance capabilities.

  • Develop performance models, system tactics, algorithms, threat models, and command and control models for new and existing system simulation frameworks.

Basic Qualifications for a Senior Principal Modeling and Simulation Engineer (T04) are:

  • High school diploma/GED and a minimum of 13+ years of experience in Computer Science, Engineering, Math, or Physics AND 9+ years modeling, simulation, and analysis of Aerospace Systems, Systems Analysis, and Design,.
