This is an opportunity to personally contribute to the development of new first-of-kind space vehicles, ground systems and missions. The programs support a range of platforms and technologies that are predominantly classified . As a member of our engineering design team, you'll work with a system architects, Concept of Operations (ConOps) developers, fault and autonomy designers, and numerous engineering disciplines (systems, hardware, software, power, payload, thermal, communications and test). Development timelines are aggressive and you will be asked to develop solutions to previously unsolved problems. You will be part of a team that generates solutions to minimally defined design spaces!, Support technology integration for and development of first-of-kind space vehicles and missions. Develop and present review packages to internal and external senior leadership. Work proactively and independently in a fast-paced, demanding atmosphere. Ensure system hardware designs have adequate redundancy for required levels of fault tolerance. Develop autonomy aligned with customer risk tolerance in the presence of anomalies. Analyze system failure modes (via failure mode effects and criticality analysis (FMECA) or fault tree analysis). Develop software requirements for onboard fault protection to detect and isolate failures and transition to spacecraft safing modes. Design autonomy or ground procedures to recover from failures. Provide occasional on-call support for system anomalies.
