Description

SAIC is seeking a Guidance, Navigation, and Control (GN&C) Modeling and Simulation Aerospace Engineer to support hypersonic weapon systems development in Crane, IN. As a critical member of our team, you will help design, model, and validate GN&C systems for hypersonic weapons, with a focus on simulation development, algorithm design, and performance analysis in a mission-critical environment. Your work will directly contribute to optimizing weapon system performance in high-speed and harsh environments.

NOTE: This is a hybrid position requiring the candidate to be in office 1-4 times per week.

JOB RESPONSIBLITIES

Develop, implement, and refine GNC algorithms for guidance, control, and navigation

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

Qualifications

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

Experience supporting DoD/DoW Weapons Systems

Experience with aerospace flight test data analysis or guidance verification
