The Opportunity: CACI is looking for an experienced Flight Software Systems Engineer to support NASA’s Moon Base flight software development at the Johnson Space Center. The Moon Base is humanity’s first permanent lunar outpost establishing human presence on the lunar surface and laying steppingstones for Mars exploration. This exciting position involves software systems engineering throughout the full software life cycle including design, development, and evaluation of software from a cybersecurity perspective and helping shape future cybersecurity practices. While any cybersecurity expertise is highly valued, experience is not required at position start, only a desire and willingness to learn.
This position requires a self-motivated, capable person with strong verbal and written communication skills. In addition to outstanding technical expertise, the individual must be very people savvy, have strong customer relationship skills, possess a positive team-player attitude, be flexible and willing to take on new assignments and responsibilities as they arise. Finally, the most qualified candidate will be an articulate speaker able to communicate complex technical ideas in a convincing manner, must share our passion for our Nation's Space Program, and share in the excitement of developing future human-rated space vehicles.
Responsibilities:
- Support development and analysis of flight software requirements.
- Coordinate development of flight software documentation. Review flight software documents, e.g., requirements, architecture, design, etc.
- Identify areas of risk and vulnerabilities within implemented flight software and develop risk mitigation plans including recommended cybersecurity controls.
- Support development of Interface Control Documents (ICDs) and Interface Requirements Documents (IRDs) to define interfaces between flight software subsystems and other spacecraft or ground systems.
- Facilitate project milestone reviews and coordinate closure of Review Item Dispositions (RIDs).
- Track and coordinate resolution of flight software bugs and defects.
- Support trade studies, analyses, and assessments as needed to develop flight software and resolve issues.
- Provide guidance and oversight of process adherence to the NASA Spacecraft Software Engineering Team (SSET) standards and processes for class A safety-critical flight software development.
- Develop and maintain a Requirements Traceability Matrix (RTM) to ensure all requirements are met.
- Interface with NASA and prime contractor engineering teams across flight software subsystem domains and NASA programs.
- Participate and present at NASA software boards as needed.
- Support integration of flight software in test and verification facilities.
• Develop software tools and scripts as needed.
- Develop software tools and scripts as needed.
Qualifications:
