• Lead cost evaluations of alternative system architectures, manufacturing approaches, supplier strategies, and sustainment concepts
• Perform sensitivity analyses, parametric modeling, and scenario-based assessments to quantify cost impacts and support trade studies
• Interpret technical baselines, system architectures, BOM structures, and manufacturing readiness levels to inform cost model assumptions
• Generate high-quality affordability reports, cost-driver summaries, and lifecycle cost visualizations for program reviews and customer briefings
• Collaborate with cross-functional teams to integrate accurate data and ensure modeling consistency across program phases
• Contribute to estimating, proposal development, and affordability inputs for major program milestones and bid reviews

Requirements

• Bachelor's degree and a minimum of 8 years of experience
