Description

SAIC is seeking a GNC Aerospace Engineer in Dahlgren, VA.

Responsibilities

• Develop, implement, and refine GNC algorithms for guidance laws, control loops, navigation filters, and state estimation.
• Support weapon system modeling and simulation, including 6 DOF (six degrees of freedom) simulation environments and subsystem integration.
• Perform trajectory analysis, mission performance evaluations, and control system stability assessments.
• Develop navigation solutions integrating IMUs, GPS, INS, seekers, and other sensor modalities.
• Conduct Monte Carlo analysis, uncertainty modeling, and system performance sensitivity studies.
• Implement GNC prototypes in MATLAB/Simulink, Python, C/C++, or equivalent simulation frameworks.
• Analyze telemetry, flight test data, and HWIL/SIL outputs to validate system performance.
• Support requirements decomposition, interface definition, and subsystem integration with E20 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
