Responsibilities:
- Provide oversight and insight of the flight software development being performed by the prime contractor for the Orion Spacecraft in the GNCP domain.
- Take initiative analyzing difficult GNCP flight software problems.
- Review and provide oversight of flight software requirements, architecture, development, design, integration, production, verification, validation, and certification.
- Support the Orion Mission Evaluation Room (MER) Flight Software Console during Artemis Missions.
- Coordinate flight software issues and resolution across programs and vehicle systems engineering teams.
- Provide technical feedback on the products produced by the prime contractor as the software for the Orion spacecraft is developed.
- Review C++ code for errors and ensure proper adherence was given to processes for code development.
- Detect areas of risk within the flight software and guide contractors through corrective action.
- Interface with NASA and prime contractor engineering teams in a government and prime contractor environment. Provide inputs for developing Certification of Flight Readiness (COFR) recommendations.
- 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.
Qualifications:
Required:
- Must be a U.S. Citizen or Permanent Resident.
- B.S. in Aerospace, Computer Science, Mechanical, Electrical, Computer or Software Engineering, or related disciplines required.
- At least five years of related software systems engineering experience with real-time safety-critical software in aerospace with expertise in one or more of the following key areas: Guidance, Navigation, Control, and Propulsion.
- Experience greater than the minimum expertise is highly valued.
- Experience working with flight software providers to correct defects in their systems.
- Experience working with software-dominant flight control systems.
- Additional consideration will be given for experience with software control systems for recent spacecraft.
- Ability to analyze requirements documents, especially those developed for NASA spacecraft contracts.
- Ability to solve complex technical problems.
- Must be flexible, open to new challenges in a dynamic environment, and possess strong technical expertise combined with strong verbal and written communication skills.
