This position supports the Dream Chaser System Autonomy and Fault Management (SAFM) team through the following:
- Design Fault Detection, Isolation, and Recovery (FDIR) algorithms considering timing, memory, and other guidelines producing the necessary documentation to support peer and engineering review board approval
- Implementing those algorithms for execution on-board the spacecraft using the vehicle’s framework for telemetry monitoring and commanding, collectively called CMAS
- Synchronize CMAS products with a Command and Telemetry Database and FSW architecture to ensure consistent build products
- Collaboration with subsystem cognizant engineers and multiple stakeholders through Integrated Product Teams to identify flight-like fault injections and translate those concepts into executable scripts to run on the mission simulation software to exercise the CMAS implementation
- Track CMAS testing activities to ensure verification with requirements traceability
- Support the creation of flight-like scenarios that realistically simulate the various mission phases for testing and verification of CMAS.
- Provide support to flight software development and hardware/software integration
- Create post-processing tools to capture test data automatically; provide an automated assessment; and prepare test data for easy reduction and analysis by reviewers
- Support to AI&T and Flight Operations during testing, mission simulation, and mission execution
- Bachelor's degree (Master’s preferred) in Aerospace Engineering or related discipline
- Related experience may be considered in lieu of required education
- Test data analysis and root-cause analysis experience
- Excellent communications skills
- Experience working with Integrated Product Teams that include stakeholders from multiple spacecraft disciplines
- Knowledge of spacecraft system and subsystem FDIR
- Understand spacecraft autonomy concepts including the creation of command sequences that execute on-board a spacecraft
- Experience writing test cases and test scripts
- Experience with: C/C++, Python, configuration management (e.g. - Subversion, Windchill), and test data reduction/review concepts
- Understand spacecraft hardware channelization, telemetry generation, and data latencies
- Understanding of peer review processes (e.g. - Jira)
- Exposure to requirements management and verification
- Experience with proper precautions for interacting and using space flight-equivalent and flight-use hardware
- Experience working with NASA; preferably human spaceflight programs
- Flight Operations Experience
- The ability to obtain and maintain a Security Clearance may be required Learn more about the background check process for Security Clearances
