• 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
