Proposal Manager in London

The Proposal Manager is responsible for leading the development, coordination, and submission of compliant, compelling, and strategically aligned proposals that support GMRE’s growth objectives within the Department of Defense and federal marketplace. This role extends beyond proposal administration and production management. The Proposal Manager serves as an operational leader within the Growth organization, responsible for driving proposal execution across cross‑functional teams while maintaining schedule discipline, communication clarity, and proposal quality under compressed timelines and evolving customer requirements.

The Proposal Manager also supports pre‑RFP and shaping activities including Requests for Information (RFIs), Rough Order of Magnitude (ROM) responses, Sources Sought notices, capability statements, technical white papers, presentations, and other customer‑facing growth artifacts. This role helps coordinate rapid‑response efforts that support opportunity qualification, customer engagement, solution shaping, and early positioning activities across the business development lifecycle.

The Proposal Manager operates as the central integrator between Capture, Business Development, Technical SMEs, Pricing, Contracts, Operations, and Executive Leadership to ensure proposal responses align with the company’s win strategy, customer priorities, and competitive positioning. This role requires strategic thinking, operational discipline, strong interpersonal judgment, and the ability to maintain execution tempo without creating unnecessary friction across the organization. The Proposal Manager must be capable of balancing tactical proposal execution with broader growth objectives while helping institutionalize repeatable proposal excellence across GMRE.

The Business Development organization operates as a high‑accountability, high‑trust environment where responsiveness, ownership, preparation, and professionalism are baseline expectations. Success in this role requires the ability to operate effectively with minimal oversight while maintaining consistent execution quality. This position is not transactional. It requires leadership, influence, composure under pressure, and the ability to coordinate diverse contributors toward a unified and compelling submission strategy.
