This role ensures compliance with applicable federal acquisition regulations (FAR/DFARS), corporate policies, and client requirements while collaborating with internal and external stakeholders to ensure that subcontractor proposals are responsive, complete, and cost-competitive. The ideal candidate will have a solid understanding of federal procurement principles, subcontracting processes, and proposal development.

• Apply required FAR/DFARS flowdowns and terms
• Maintain audit-ready proposal files in SharePoint, Costpoint, AMRO, or similar systems
• Conduct price/cost analysis to assess competitiveness and risk
• Coordinate stakeholders throughout the proposal cycle
• Identify subcontract-related risks and implement mitigation strategies
