Principal SAP S/4HANA Architect & Lead

Candidates for this position are preferred to be based in Boston, USA and will be expected to comply with their team's hybrid work schedule requirements.

Who We Are

The SAP Engineering team is responsible for maintaining a highly complex SAP installation used in the Finance department for all General Ledger, Accounts Payable, and Accounts Receivable functions. The vast majority of operations are fully automated, with integrations that generate more than 200 million transactions per month. We have developed complex services that allow us to post transactions to SAP from internal home-grown systems and external third-party cloud-based systems. We are looking for a Principal SAP S/4HANA Architect & Lead to own the strategy, architecture, and delivery of our S/4HANA platform. This role serves as the primary functional and technical authority, driving enterprise transformation, ensuring platform stability, and enabling future capabilities including AI and automation.

What You'll Do

• Own the end-to-end S/4HANA architecture and roadmap, aligning SAP capabilities with Wayfair's enterprise strategy and high-scale engineering requirements.
• Serve as the lead architect for SAP S/4HANA Finance (FICO), designing scalable, compliant processes for GL, AP/AR, Fixed Assets, CO, and granular financial reporting.
• Establish "Clean Core" principles, defining standards for extensibility via SAP BTP and ensuring API-led, event-driven integration with our internal Java/Python services.
• Lead large-scale transformation programs, including S/4HANA upgrades (2021 2023/2025) and the evolution of our data architecture and master data strategy.
• Identify and enable AI/ML use cases (e.g., financial forecasting, intelligent automation) by leveraging SAP BTP, AI Core, and internal Wayfair AI platforms.
• Define and govern platform health, including data archiving/lifecycle strategies (ILM), RICEFW standards, and custom vs. standard decision frameworks.
• Own change, release, and transport management (ChaRM/CTS+), integrating SAP delivery into modern CI/CD mindsets to ensure high-quality, low-risk deployments.
• Act as a trusted advisor to Finance, Accounting, and FP&A leaders, supporting cross-functional decisions impacting revenue, cost, and inventory.
• Lead and mentor onshore and offshore engineering teams, fostering a culture of technical excellence and architectural integrity.

We Are a Match Because You Have:

• 15+ years of SAP experience, with at least 8+ years in dedicated Architecture roles managing complex enterprise environments.
• Deep expertise in SAP S/4HANA Finance (FICO) and a proven track record of successful greenfield or brownfield implementations and upgrades (v2021+).
• Strong technical command of SAP BTP, integration technologies, and data architecture within a global, distributed environment.
• Experience with high-volume integrations, understanding how SAP interacts with non-SAP systems (Java/Python microservices, cloud-native platforms).
• Demonstrated leadership in managing global delivery models (onshore/offshore) and driving architecture governance across large-scale programs.
• A "Clean Core" mindset, with the ability to balance business requirements against the need for platform maintainability and upgradeability.
• Strong communication skills, capable of translating complex technical roadmaps into business value for executive stakeholders.

Nice to Have:

• Experience with SAP ILM (Information Lifecycle Management) and data archiving strategies.
• Exposure to AI/ML enablement within SAP or integration with external GenAI providers (Gemini, OpenAI).
• Background in Retail, eCommerce, or Supply Chain-integrated environments (P2P, O2C).
• Familiarity with modern DevOps practices and containerized environments.
