Senior GSA MAS Contract Vehicle Manager

Urrly•Reston, VA

71d•$155,000 - $170,000•Remote

About The Position

The Senior GSA MAS Contract Vehicle Manager is a hands-on, client-facing role helping government contractors maintain, manage, and get more value from their GSA Multiple Award Schedule contracts. The work centers on post-award GSA MAS administration, including modifications, compliance, pricing and catalog updates, SIN strategy, and ongoing Schedule maintenance. Deep practical MAS administration experience is the key differentiator; broader GWAC, OASIS+, IDIQ, BPA, and proposal experience is valuable but secondary. The manager oversees Schedule maintenance across multiple GovCon clients, advises them on contract strategy and compliance, and coordinates with client executives and internal teams to move contract actions forward. The role also supports initial GSA MAS offers, task-order and eBuy activity as needed, and the development of repeatable internal processes. It is fully remote within the United States, in a client-facing consulting environment, with occasional travel possible.
