Proposal Manager

C5MI is not your typical consulting firm. We are a high-performance team of SAP and supply chain experts who solve complex, mission critical challenges for organizations that cannot afford failure. We hire consultants who thrive in complexity, move fast, take ownership, and deliver under pressure. At C5MI, you will not be siloed or stuck in theory. You will be hands on, client facing, and directly influencing outcomes that matter. Our culture rewards initiative, accountability, and continuous growth. This is a place where your expertise is valued, your work is meaningful, and your performance truly matters. If you’re energized by learning through real-world challenges, collaborating with top-tier talent, and expanding your capabilities every day, C5MI is where strong consultants level up. Position Summary: C5MI is seeking an experienced Proposal Manager to lead the company's federal proposal function from solicitation release through submission. This fully remote position reports to the VP of Business Development and serves as C5MI's senior proposal professional. The Proposal Manager 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 proposal execution and the processes behind it. On each pursuit, you will analyze the solicitation, build the schedule and compliance matrix, run the kickoff and color reviews, and write and edit much of the content yourself. Across the portfolio, you will maintain C5MI's proposal standards, templates, and content library, and you will engage consultants or contract writers when workload exceeds capacity. Our work centers on ERP, supply chains, logistics, and data analytics for Department of Defense and civilian agencies, so the Proposal Manager must interpret FAR and DFARS requirements with confidence and translate complex technical solutions into clear narrative for government evaluation and scoring.
