Responsibilities:

  • Review and oversight of flight software requirements development, design, integration, production, verification, validation, and certification.
  • Perform systems engineering, such as hazard analysis, on vehicle subsystem domains.
  • Coordinate flight software issues and resolution across programs and vehicle systems engineering teams.
  • Detect areas of risk within the flight software and guide contractors through corrective action.
  • Evaluate prime contractor flight software architecture, design, and implementation.
  • Oversight of integration of flight software in test and verification facilities.
  • Interface with NASA and prime contractor engineering teams.
  • Provide inputs for developing Certification of Flight Readiness (COFR) recommendations.
  • Provide mission support including monitoring and evaluating flight operations and troubleshooting anomalies during commercial spacecraft flights in the Mission Evaluation Room (MER).
  • This work takes place at NASA/JSC in Houston, TX, a highly stimulating and dynamic environment that is critical in human space flight and the space exploration initiative.
