Senior GSA MAS Contract Vehicle Manager

Urrly•Reston, VA

4d•$155,000 - $170,000•Remote

About The Position

This is a client-facing, hands-on role focused on GSA MAS maintenance, modifications, compliance, pricing and catalog updates, SIN strategy, and ongoing Schedule administration. The core need is someone who understands how GSA MAS contracts actually work after award, how to keep them compliant, and how to guide clients through the administrative and strategic decisions required to maintain and expand their Schedule. This role prioritizes hands-on GSA MAS maintenance capability first. GWAC, OASIS+, IDIQ, BPA, and broader proposal experience is valuable, but MAS administration depth is the key differentiator.

Requirements

Direct, hands-on experience with GSA MAS or GSA Schedule administration.
Experience preparing or supporting eOffer and/or eMod actions.
Experience with SIN additions or changes, labor category updates, pricing updates, catalog updates, or similar MAS modifications.
Understanding of post-award GSA MAS maintenance requirements, not just proposal or capture support.
Experience supporting GSA MAS compliance, including Schedule documentation, reporting requirements, renewals, modifications, and client readiness.
Ability to communicate directly with GovCon clients and explain MAS requirements in plain English.
Strong project-management skills across multiple clients, deadlines, and contract-vehicle actions.
Experience working with federal contractors, GovCon advisory firms, GSA Schedule consulting firms, or similar contractor-side environments.
Strong attention to detail and comfort working through complex government requirements, templates, portals, and documentation.
Ability to operate independently in a remote, client-facing consulting environment.

Nice To Haves

Experience helping companies secure new GSA MAS awards.
Experience with GSA eBuy, GSA Advantage, IFF reporting, TDR reporting, SIP/catalog files, CALC/pricing research, or MAS renewal actions.
Experience advising clients on MAS growth strategy, including how to position their Schedule for agency demand.
Familiarity with OASIS+, GWACs, IDIQs, BPAs, or other federal contract vehicles.
Experience with Symphony or scorecard-driven vehicle submissions.
Background at a GSA consulting firm, GovCon advisory firm, federal proposal consultancy, or government-contractor contracts/proposal team.
Experience balancing MAS maintenance work with proposal, task-order, or contract-vehicle submission support.
