  • Design and develop guidance algorithms to deliver mission capability across a range of operating conditions.
  • Design, implement, and tune controllers to meet vehicle stability, control, and performance requirements.
  • Integrate multi-sensor feedback to support navigation, tracking, and state estimation solutions.
• System Evaluation and Technical Communication
  • Assess system performance, capability, robustness, and sensitivity through analysis, simulation, and test.
  • Perform root-cause analysis of anomalies and support corrective action development.
  • Prepare and communicate design, analysis, and test results to internal and external stakeholders.
• Demonstrated technical competency in at least one guidance, navigation, and control (GNC) discipline, such as:
