Position Summary: 

C5MI is seeking a Proposal Manager to lead federal proposal efforts from solicitation release through submission. This fully remote position reports to the Director of Proposal Development and works closely with business development, capture, contracts, pricing, and technical subject matter experts (SMEs) to produce compliant, competitive proposals for defense and civilian federal customers. 

The Proposal Manager owns day-to-day execution on assigned pursuits, which range from RFIs and sources sought responses to task orders, IDIQs, and contract vehicle on-ramps. You'll build the schedule and compliance matrix, run the kickoff and color reviews, write and edit content, and keep contributors on track toward the deadline. Our work centers on ERP, supply chains, logistics, and data analytics, so the Proposal Manager must translate complex technical solutions into clear narrative for government evaluation and scoring. This role is a strong fit for a proposal professional with several years of hands-on experience who aims to manage full pursuits independently and help shape how C5MI's proposal function grows.

Essential Functions & Responsibilities:

• Manage assigned proposals through the full lifecycle, including RFIs, sources sought notices, RFPs, RFQs, task orders, and contract vehicle on-ramps, often with multiple pursuits running concurrently
• Analyze solicitations (Sections L and M, SOW/PWS, evaluation criteria, and submission instructions) and translate requirements into annotated outlines, compliance matrices, and clear writing assignments
• Build and maintain proposal schedules, lead kickoff meetings, and hold contributors accountable to milestone deadlines
• Partner with capture and business development leads to carry win themes, discriminators, and customer insight into proposal content
• Write, edit, and rewrite technical, management, and past performance sections, turning SME input into polished, evaluator-friendly narrative
