• 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

• Bachelor’s degree in Aerospace Engineering, Mechanical Engineering, Electrical Engineering, Physics, or related discipline (Master’s preferred)

• 3+ years' experience in GNC engineering, missile guidance, flight controls, or related system modeling

• 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

Preferred Qualifications

• 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

SECURITY CLEARANCE REQUIRED

• Must be able to obtain and maintain a security clearance at the Secret level, Interim clearance required to start. SAIC will sponsor clearance. Current active Secret clearance preferred.

Target salary range: $80,001 - $120,000. The estimate displayed represents the typical salary range for this position based on experience and other factors.
