  • Interface with cross-discipline teams to integrate GNC software with vehicle hardware
  • Serve as a GNC console operator for launch operations and perform post-flight analysis to improve vehicle models
  • Author technical documentation and analysis reports that communicate GNC concepts and results to diverse audiences
  • Build proficiency across core GNC competencies while contributing to continuous improvement of GNC processes and tools
QUALIFICATIONSRequired
  • Bachelor's degree in aerospace engineering, mechanical engineering, electrical engineering, physics, mathematics, computer science, or related field
  • 2-5 years of professional experience in aerospace guidance, navigation, and control, or related technical discipline
  • Understanding of launch vehicle flight mechanics and attitude dynamics

  • Experience with Python for scripting, data analysis, and visualization
  • Familiarity with C++ for real-time or flight-critical applications
  • Understanding of software development best practices including version control (Git), code documentation, and testing
  • Strong written and verbal communication skills
Desired
  • Advanced degree (master's or PhD) in aerospace engineering or related field with focus on GNC, flight mechanics, or controls
  • Experience supporting launch vehicle GNC across development, integration, and flight
  • Proficiency in C++ for embedded systems or real-time applications
  • Knowledge of state estimation techniques including Kalman filtering, sensor fusion, and covariance analysis
  • Knowledge of numerical optimization and targeting methods applied to trajectory design
  • Familiarity with modern flight software frameworks and real-time operating systems
  • Familiarity with CI/CD workflows and automated testing practices
