Job description

Description

SAIC is seeking a Guidance, Navigation, and Control (GN&C) Modeling and Simulation Aerospace Engineer to support hypersonic weapon systems development. 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.
Responsibilities:

• 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 presentationsi>
• Participate in technical reviews, design sessions, and engineering working groups with government and contractor personnel

Qualifications

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

• 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. 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.
