Bowhead is seeking a Senior SAP S/4

HANA Functional Lead – Plan-to-Stock (P2S) & Defense & Security to provide consultative support to the Navy ERP Program Office in Washington, D.C. The selected candidate will serve as the Government’s senior functional advisor for the Plan-to-Stock workstream supporting ERP+ modernization and implementation of SAP S/4

HANA and SAP Defense & Security (D&S). This position can be remote.

This is a senior advisory role—not a configuration or transactional support position. The successful candidate will operate at the intersection of functional architecture, enterprise integration, governance, and business transformation while advising Government leadership throughout the ERP+ modernization lifecycle.

As the program transitions from requirements definition into implementation, this position will evolve into an Independent Verification & Validation (IV&V) role, providing objective oversight of System Integrator (SI) functional designs, configuration decisions, integrations, and solution implementation to ensure alignment with Government-approved requirements, SAP leading practices, enterprise architecture, and long-term sustainment.

• Provide strategic functional leadership throughout the ERP+ modernization lifecycle.
• Lead Plan-to-Stock (P2S) fit-to-standard workshops and requirements refinement.
• Support decomposition of L2, L3, and L4 business capabilities into implementable solution concepts.
• Lead discussions with Navy stakeholders across multiple commands and functional communities.
• Provide recommendations that maximize standard SAP capabilities while minimizing customization.
• Evaluate the enterprise-wide impacts of proposed Plan-to-Stock business processes and solution designs across Procurement, Inventory Management, Warehouse Management, Supply Planning, Defense & Security capabilities, Data Management, Reporting, Cybersecurity, and external enterprise interfaces, ensuring integrated solutions support Government-approved business requirements and SAP leading practices.
• Prepare executive briefings, governance artifacts, business cases, and decision support materials.
• Support release planning, production readiness, testing strategy, deployment planning, and post-go-live stabilization.

Independent Verification & Validation (IV&V) / Solution Oversight

• Serve as the Government’s independent functional advisor during design, configuration, and implementation.
• Review functional designs, configuration proposals, and solution documentation for compliance with approved requirements.
• Validate that proposed solutions satisfy approved L2/L3/L4 capabilities and SAP leading practices.
• Identify functional gaps, design risks, integration issues, and unnecessary customization.
• Evaluate impacts to business processes, cybersecurity, audit readiness, sustainment, performance, and maintainability.
• Support design reviews, architecture reviews, milestone decision events, and Government acceptance activities.

SAP Defense & Security Focus

• Advise on Force Structure, Authorized Materiel, Unit Readiness, Equipment Readiness, Deployment Logistics, Operational Inventory Visibility, Asset Accountability, and Weapon System Sustainment.
• Assist the Government in leveraging SAP D&S capabilities to replace legacy customizations where practical.
