GNC Engineer III, Navigation

Role Overview

• Design, analyze, and tune launch vehicle navigation software to ensure accurate state estimation from launch to orbit
• Implement advanced filtering techniques using inertial sensor and GNSS measurements
• Develop navigation systems robust to error sources including inertial sensor bias, GNSS signal degradation, noise, and sensor misalignments
• Establish technical standards and validation methodologies for navigation system design, software development, and hardware-in-the-loop testing
• Conduct covariance analysis, sensitivity studies, and performance optimization for navigation systems under nominal and off-nominal flight conditions
• Support hardware-in-the-loop test campaigns for integrated GNC systems including navigation algorithm validation, flight software verification, and system-level performance testing
• Drive resolution of complex GNC challenges requiring deep technical expertise and rapid problem-solving
• Provide technical direction on system architecture and serve as subject matter expert for launch vehicle state estimation
• Mentor junior engineers in estimation theory and flight software development
• Author technical documentation and analysis reports that communicate GNC concepts and results to diverse audiences
• Interface with cross-discipline teams to integrate navigation software with vehicle hardware
• Serve as a GNC console operator for launch operations and perform post-flight analysis to improve vehicle models
• Champion continuous improvement initiatives for GNC processes, tools, and operational efficiency
