Global Integration Architect Lead – SAP Platforms

The Global Integration Architect Lead is the senior technical authority responsible for defining, governing, and evolving the enterprise integration architecture across the global SAP ecosystem. This role owns cross‑system integration strategy, API standards, and event‑driven patterns that connect SAP S/4HANA, SAP Ariba, SAP SuccessFactors, and non‑SAP platforms at scale. Operating as a design authority and architectural leader, the role ensures integrations are secure, scalable, resilient, and Clean‑Core compliant, while enabling rapid business transformation and global process standardization. The Global Integration Architect Lead partners closely with Enterprise Architects, Solution Architects, Product Owners, and delivery partners to ensure integration decisions support long‑term enterprise outcomes—not just short‑term program delivery.

• Establish standard integration patterns (API‑led, event‑driven, batch, synchronous/asynchronous) aligned with enterprise architecture principles.
• Act as the final design authority for complex, cross‑domain integrations involving SAP S/4HANA, Ariba, SuccessFactors, and third‑party systems.
• Ensure integration designs support global business processes (O2C, P2P, R2R, H2R) and enterprise data models.

• Deep hands‑on experience integrating SAP S/4HANA, SAP Ariba, and SAP SuccessFactors in large global landscapes.
• Strong expertise in SAP Integration Suite, including CPI and API Management.
• Proven experience designing API‑led and event‑driven architectures at enterprise scale.
• Strong understanding of SAP standard APIs, data objects, and integration best practices.

Technical & Architectural Skills

• Advanced knowledge of RESTful APIs, JSON/XML, OAuth2, SAML, certificate‑based security, and integration performance tuning.
• Experience with hybrid integration scenarios (SAP cloud, hyperscalers, on‑prem systems).
• Ability to translate business requirements into clear, durable integration architectures rather than one‑off solutions.

Leadership & Enterprise Skills

• Demonstrated ability to act as a global design authority, influencing without direct control.
• Strong stakeholder management skills across IT, business, and external partners.
• Experience working in large, matrixed, global organizations with multiple delivery teams.
