Integration Architect

• Design and govern the integration specifications, API contracts, and interface patterns linking SAP S/4HANA with core retail back-office, POS, and edge systems.
• Architect robust, real-time, event-driven, and batch data-flow models optimised for a modern SAP ecosystem, heavily leveraging tools like SAP Integration Suite.
• Design complex interim integration states to manage parallel delivery, including ensuring seamless data synchronisation and zero business disruption while transitioning from legacy ERP environments to S/4HANA.
• Drive the roadmap to rationalise a fragmented, multi-technology legacy integration footprint, consolidating it into a streamlined, consistent, and highly scalable target-state integration platform.
• Define strict non-functional requirements (throughput, latency, error-handling, resilience, and end-to-end monitoring) and establish a unified interface security approach across all SAP and retail boundary systems.
• Build and execute targeted proofs of concept (PoCs) to validate high-risk, high-volume, or highly complex SAP integration points before designs are finalised.
• Act as the primary integration counterpart to program architects and external Systems Integrators, critically reviewing, challenging, and validating vendor-proposed SAP integration designs.
• Inject expert integration analysis and recommendations into cross-program Key Design Decisions (KDDs), ensuring dependencies and structural risks are surfaced early.
• Stay at the forefront of SAP BTP (Business Technology Platform) evolution, modern API management, and event-streaming paradigms, applying these to a complex, multi-site corporate retail environment.
• Maintain flawless, unambiguous integration documentation, including patterns, schemas, and implementation guides, to allow distributed development teams to build without friction.
• Ensure data privacy and security are hardcoded into every interface, strictly meeting regional regulatory compliance and healthcare/pharmacy data obligations where relevant.

• 7+ years in technology roles, with a proven track record operating as an Integration Architect on large-scale enterprise programs.
• Extensive, hands-on experience designing and executing integrations explicitly for SAP S/4HANA.
• Strong technical proficiency with the SAP Integration Suite (Advanced Event Mesh, Cloud Integration, API Management) and an understanding of how to transition away from legacy SAP middleware or point-to-point setups.
• Mastery of API-led connectivity, event-driven architecture (EDA), canonical data modeling, and handling both high-velocity real-time events and high-volume batch processing.
• Proven capability designing data-bridge and coexistence architectures required during multi-year ERP migrations.
• Demonstrated ability to confidently review, critique, and align technical designs delivered by major global Systems Integrators.
• Solid understanding of cloud-native integration patterns (e.g., AWS environment topologies).

Experience with retail enterprise ecosystems, specifically Point-of-Sale (POS) systems, store operations, or dispensary/pharmacy data structures.
