Modeling and Simulation Engineer

SAIC • Crane, IN

4d

About The Position

SAIC is seeking a Guidance, Navigation, and Control (GN&C) Modeling and Simulation Aerospace Engineer to support hypersonic weapon systems development. The role involves designing, modeling, and validating GN&C systems, with an emphasis on simulation development, algorithm design, and performance analysis in high-speed and harsh environments. The position contributes to optimizing weapon system performance through modeling, testing, and analysis.

Requirements

• Bachelor’s degree in Aerospace Engineering, Mechanical Engineering, Electrical Engineering, Physics, or a related discipline.
• At least 3 years of experience in GNC engineering, missile guidance, flight controls, or related system modeling.
• Proficiency in MATLAB/Simulink, Python, C/C++, FORTRAN, or equivalent simulation frameworks or programming languages.
• Demonstrated ability, through coursework or professional experience, to perform one or more GNC or M&S assignments: develop and analyze guidance, navigation, autopilot, inertial tracking, or servo-control algorithms; develop or verify/validate complex vehicle models and simulations such as missile 6-DOF simulations; or apply strong mathematics skills in linear algebra, matrix mathematics, statistics, trigonometry, and coordinate transformations.
• Must be able to obtain and maintain a Secret-level security clearance; an interim clearance is required to start. SAIC will sponsor the clearance.

Nice To Haves

• Master’s degree.
• 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.
• Experience supporting DoD/DoW weapons systems.
• Experience with aerospace flight-test data analysis or guidance verification.
• Current active Secret clearance.

Responsibilities

• Develop, implement, and refine guidance, control, and navigation algorithms.
• Support hypersonic weapon system modeling and simulation, including six-degrees-of-freedom (6 DOF) 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 systems-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.
