   • Proficient with Digital Engineering tools (DOORS, Cameo, Microsoft Office Suite, Jira, Confluence)
   • Experience with risk management, trade studies, and decision analysis
   • Typically requires a degree in Science, Technology, Engineering or Mathematics (STEM) and minimum 8 years prior relevant experience or an Advanced Degree in a related field and minimum 5 years of experience 

Qualifications We Prefer
