We are looking for dedicated and motivated candidates who can grow with the company. At Greystones, we recognize that everyone brings unique talents and skill sets that contribute to a highly competent team delivering quality solutions.

Greystones is hiring for a Part-time, Proposal Manager to lead the development and delivery of compliant, compelling proposals across our federal and Department of War (DoW) pursuits.

The ideal candidate is an experienced proposal professional who has managed responses to DoD solicitations, SeaPort (SeaPort-NxG) task order requests, and Commercial Solutions Opening (CSO) opportunities, and who can move quickly, manage multiple contributors, and produce high-quality submissions under tight deadlines. This is a flexible, project-based role well suited to a seasoned proposal manager who wants meaningful, mission-focused work without a full-time commitment.

This is a remote, part-time position within the Contracts department, reporting to the Director of Operations.
