• Analyze modeling results, identify discrepancies, and adjust laydowns to ensure accurate and safe test execution.
• Build complete PNT mission packages, including strawman work products, technical documentation, and PowerPoint briefing materials.
• Prepare and submit frequency requests with supporting modeling and analysis.
• Create geospatial representations of interference footprints using Google Earth or Secret Internet Protocol Router Network (SIPRNet) Map of the World.
• Coordinate with test ranges, mission planners, program offices, and EW/PNT stakeholders to ensure modeling accuracy and event readiness.
• Maintain and manage modeling products and documentation in secure SIPR environments.
• Apply RF system engineering principles to evaluate modeling outputs and mission impacts.

Required Qualifications

• BS or BA degree
• 8 years of related experience
• Proficiency with GIANT (GPS Interference and Navigation Tool)
• Proficiency with Builder (Navy frequency‑modeling software)
