York's complete Space Segment Solution includes spacecraft production, payload integration, system integration & test, launch services, ground segment services, and mission operations, enabling customers to leverage York's existing technology solutions to get to orbit rapidly and responsively.

York Space Systems is seeking an experienced Proposal Manager III to lead the development and submission of competitive proposals in support of U.S. Government space capability programs. This role requires an active TS/SCI clearance and is based on-site at our facility, given the sensitivity of program information and the need for direct, secure collaboration with capture, business development, technical, contracts, supply chain, and pricing teams.

The Proposal Manager III will own the end-to-end proposal lifecycle for space-focused pursuits, from color team planning and reviews through final submission, ensuring every deliverable is compliant, compelling, and aligned to both customer requirements and company win strategy. The ideal candidate has a proven track record managing complex, multi-volume proposals in the Aerospace & Defense sector, with direct experience supporting space systems, launch, ground segment, C2, or related mission areas.

This role will be fully on-site in our Greenwood Village, Colorado office.
