  • Support hypersonic weapon system modeling and simulation, including 6 DOF (six degrees of freedom) simulations
  • Perform trajectory analysis, mission performance evaluations, and control system stability assessments
  • Analyze telemetry, flight test data, and HWIL/SIL outputs to validate system performance
  • Conduct Monte Carlo analysis, uncertainty modeling, and system performance sensitivity studies
  • Evaluate system performance in complex scenarios and environments and verify system and subsystem level requirements
  • Support requirements decomposition, interface definition, and subsystem integration with system engineering teams
  • Document models, test results, algorithm behavior, and performance in technical reports and presentations
  • Participate in technical reviews, design sessions, and engineering working groups with government and contractor personnel

REQUIRED EDUCATION AND EXPERIENCE:

  • Bachelor’s degree in Aerospace Engineering, Mechanical Engineering, Electrical Engineering, Physics, or related discipline (Master’s preferred) and 3 or more years experience
  • Experience in GNC engineering, missile guidance, flight controls, or related system modeling
  • Interim clearance required with the ability to obtain and maintain a security clearance at the Secret level
  • Proficiency in MATLAB/Simulink, Python, C/C++, FORTRAN or equivalent simulation frameworks/programming languages
  • Candidate must have demonstrated the ability to perform one or more of the following Guidance, Navigation and Control (GNC) or Modeling and Simulation (M&S) assignments based on completed course work or professional experience:
  • Develop and analyze algorithms such as guidance, navigation, autopilot, inertial tracking, and servo control algorithms
  • Develop and/or verify/validate complex vehicle models and simulations such as missile 6-degree-of-freedom simulations
  • Demonstrate strong math skills in the areas of linear algebra, matrix math, statistics, trigonometry, and coordinate transformations

PREFFERRED EXPERIENCE:

  • Familiarity with hardware in the loop (HWIL) or software in the loop (SIL) environments
  • Experience supporting missile systems, unmanned systems, or weapons/flight dynamics programs
