An Enterprise Architect for S/4

HANA Integration has to oversee the technical direction for moving from older SAP ECC systems to S/4

HANA from integration perspective, ensuring integration efforts uphold security, scalability, and adhere to best practice principles such as a "Clean Core"

KEY RESPONSIBILITIES

• Provide senior leadership in setting the technical direction for migrating from SAP ECC to S/4
  
  HANA, ensuring integration aligns with security, scalability, and "Clean Core" best practices.
• Design and manage the overall integration strategy for S/4
  
  HANA 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

• At least 10 years of experience in SAP architecture, with a minimum of 3 years dedicated to S/4
  
  HANA migration projects.
• Proven experience designing and leading SAP ECC → S/4
  
  HANA transformations (greenfield/brownfield/selective data transition).
• Strong understanding of S/4
  
  HANA core concepts (digital core, extensibility, clean core approach, integration strategy).
• Strong experience with SAP Integration Suite (CPI) and integration patterns.
• Working knowledge of SAP PI/PO (for legacy estates and migration planning).
• Expertise with SAP integration technologies and protocols: OData, REST, SOAP, RFC, IDoc, EDI, proxy services, file-based integration.
• Ability to define end-to-end enterprise integration architecture across SAP and non-SAP applications (CRM, eCommerce, ERP, PLM, HR, Finance, Data platforms).
• Expertise in integration patterns: canonical model, anti-corruption layer, orchestration vs choreography, sync vs async design.

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.
• Experience designing secure integrations: OAuth2, SAML, mTLS, certificates, secrets management, least privilege.
• The familiarity with compliance controls and auditability for enterprise integrations (logging, traceability, retention).
• Deep understanding of hybrid and cloud architecture, especially with platforms like Azure, AWS, or GCP.
