• Design and manage the overall integration strategy for S/4HANA migration projects, including defining future-state architectures.
• Make critical decisions on migration approaches such as Greenfield or Brownfield, ensuring all integrations adhere to enterprise-wide standards.
• Develop integration strategies encompassing SAP BTP, external systems, and legacy environments to support hybrid landscapes.
• Lead key architectural choices, including phased transitions, coexistence models, and selection of middleware platforms.
• Establish and maintain standards for interface development in line with SAP best practices.
• Analyze existing ECC customizations and design migration strategies to minimize technical debt.
• Collaborate with business and functional teams to translate complex business requirements into robust technical solutions.
• Anticipate technical risks, and develop mitigation plans for challenges related to data harmonization, system consolidation, and interdependencies.
• Demonstrate strong expertise in SAP BTP, SAP PI/PO, APIs, OData, and Event Mesh.
• Apply knowledge of architecture frameworks such as TOGAF or similar, with proven experience in landscape rationalization.

YOU MUST HAVE

WE VALUE

• Experience defining enterprise API strategy: API lifecycle, versioning, governance, security, throttling, documentation standards.
• Experience with event-driven architectures (events, queues/streams) and patterns such as pub/sub, saga, outbox (SAP events/enterprise messaging is a plus).
• Strong understanding of microservices integration, service mesh concepts (nice-to-have), and integration best practices in hybrid environments.
