The ideal candidate will possess substantive hands-on experience in GCSS-MC financial management or supply/maintenance operations and will have demonstrated the ability to advise and support users across a broad range of organizational contexts and mission requirements.

Key Responsibilities & Duties

Core SME Functions

• Serve as a functional SME for GCSS-MC, providing expert guidance to end users, unit administrators, and staff across Marine Corps commands on system processes, transactions, and business rules.
• Analyze user-reported issues and business process challenges; develop and communicate practical, experience-based solutions within the GCSS-MC environment.
• Develop and maintain SOPs, quick reference guides, job aids, and training materials that translate GCSS-MC system behavior into actionable user guidance.
• Support functional testing, user acceptance testing (UAT), and system validation activities associated with configuration changes, upgrades, or new capability rollouts.

Financial Management

• Provide SME support for GCSS-MC financial management functions including obligation management, expenditure processing, reimbursable order workflows, and fund control transactions.
• Assist users with financial reconciliation, transaction error resolution, and end-of-period closeout procedures within GCSS-MC.
• Advise on GCSS-MC interfaces with enterprise financial systems and support users in identifying and resolving interface discrepancies.
• Support audit readiness and financial improvement activities by advising on system-generated documentation, transaction audit trails, and data integrity practices.
• Develop and deliver financial management-focused user training and functional walkthroughs for a diverse Marine Corps user base.

Supply/Maintenance

• Provide SME support for GCSS-MC supply chain and maintenance management functions including demand management, requisitioning, inventory control, asset visibility, and equipment readiness reporting.
• Assist users with work order management, equipment lifecycle tracking, and maintenance business process execution within GCSS-MC.
• Advise on supply/maintenance module configuration, transaction workflows, and resolution of functional discrepancies at the unit and activity level.
• Support materiel obligation validation, supply chain data quality reviews, and inventory audit support activities across the enterprise user community.
• Develop and deliver supply/maintenance-focused user training and functional walkthroughs tailored to the needs of Marine Corps operating forces and supporting establishments.

Collaboration & Communication

• Serve as a trusted liaison between end users and technical/program teams — translating operational needs into clear system guidance and actionable recommendations.
• Communicate effectively across a wide range of stakeholders including unit-level users, G-4/G-8 staffs, system administrators, and program office representatives.
• Contribute to continuous improvement of enterprise support processes by identifying recurring user issues, trends, and training gaps and recommending solutions.

Required Qualifications

• 5+ years of hands-on experience with GCSS-Marine Corps (GCSS-MC) in either a financial management or supply/maintenance functional capacity.
• Demonstrated expertise in one or more GCSS-MC functional domains: financial management (obligations, expenditures, reimbursables, fund control) or supply/maintenance (supply chain, requisitioning, work order management, inventory control).
• Proven ability to clearly communicate complex processes and procedures to users with varying levels of system proficiency.
• Experience supporting Marine Corps operating forces, supporting establishments, or subordinate activities in a system support or advisory capacity.
• Active DoD clearance or the ability to obtain one.
• Local candidates required — must reside in the Quantico, VA / National Capital Region (NCR) area and report on-site at Quantico, VA.

Preferred Qualifications

• Breadth across both financial management and supply/maintenance functional domains within GCSS-MC.
• Experience with GCSS-MC enterprise support, sustainment, or modernization programs including system upgrades or capability transition activities.
• Familiarity with FIAR compliance, audit readiness activities, or IG/GAO audit support in a DoD financial management or logistics context.
