ERP Material Systems Lead

About the role

We are seeking a Senior SAP S/4HANA Solution Architect – Procure to Pay (P2P) to own the end-to-end design and architecture of Slate’s procurement and supplier management processes as part of the company’s migration from NetSuite to SAP S/4HANA. Reporting to Slate’s Head of ERP Systems, this role serves as the internal counterpart to our implementation partner’s Solution Architect and is accountable for establishing the long-term SAP Procure-to-Pay design strategy.

The successful candidate will lead the architecture, configuration direction, and process design for SAP Materials Management (MM), Procurement, Inventory Management, Logistics Invoice Verification, Supplier Master Data, and integration points with Finance, Supply Chain, Manufacturing, and Warehouse operations. As the senior functional authority for Procure-to-Pay, this individual will ensure that SAP design decisions support operational scalability, strong financial controls, and efficient procurement execution across the enterprise.

This is a permanent product team role, not a project-based assignment. The selected candidate will help launch the initial SAP S/4HANA platform and then own the ongoing evolution of Procure-to-Pay capabilities for years to come.

Responsibilities

• Lead the design and implementation of SAP S/4HANA MM solutions across procurement and inventory management processes.
• Define end-to-end solution architecture aligned with enterprise business requirements and SAP best practices.
• Provide functional leadership for SAP MM-related projects, assessments, enhancements, and transformation initiatives.
• Drive standardization, process simplification, and adoption of SAP S/4HANA capabilities.

Requirements

• Bachelor’s degree in information systems, Supply Chain Management, Business Administration, Engineering, or related field.
• 10+ years of SAP MM experience, including multiple full lifecycle SAP implementations.
• 3+ years of SAP S/4HANA solution architecture experience.
• Experience with SAP S/4HANA Green field implementation or transformation programs.
• Strong understanding of procurement and supply chain business processes.
• A clear, defensible point of view on clean-core and fit-to-standard design, with the credibility to serve as the implementation partner's counterpart and hold the line against unnecessary customization.
• Experience writing functional specifications, leading finance-side user acceptance testing, and partnering with implementation partners and IT through go-live and stabilization.
• Familiarity with SOX requirements for finance systems, ideally in a pre-IPO or recently public-company environment.
• Comfortable in a fast-paced, growth-stage environment building a system rather than maintaining one.

Pay

Base Pay Range (Annual): $171,191.48 - $285,319.13 USD

Benefits

• Medical, dental, vision, life insurance, and disability insurance.
• Vacation and 401k.
• Eligibility to participate in the equity program and/or a discretionary annual incentive program, subject to the rules governing such programs.
