• Support verification planning by defining verification methods and collaborating with test teams

• Familiarity with GPS/PNT systems
• Proficiency with IBM Rational DOORS and requirements management best practices
• Proficiency with DOORS DXL scripting
• Experience with systems engineering activities including requirement derivation, interface definition, allocation, integration, requirement sell‑off, analysis, test procedure development, test execution, and results evaluation
• Familiarity with generating and maintaining technical documentation such as specifications, ICDs, Test Requirements Documents (TRDs), and Verification Cross‑Reference Matrices
• Proficient with Digital Engineering tools (DOORS, Cameo, Microsoft Office Suite, Jira, Confluence)
• Typically requires a degree in Science, Technology, Engineering or Mathematics (STEM) and minimum 5 years prior relevant experience or an Advanced Degree in a related field and minimum 3 years of experience

• Strong understanding of systems engineering principles and lifecycle (concept → design → integration → verification → validation)
  Ability to understand how system components interact
• Ability to identify requirement gaps, inconsistencies, conflicts, or duplication
• Familiarity with Engineering Lifecycle Optimization (ELO) – Publishing
• Exposure to Agile development workflows (Jira, Confluence)
• Experience with Model‑Based System Engineering (MBSE) practices
