Job description

Role: Test Architect – SAP S/4HANA Brownfield Migration

Workplace type: 100% Onsite

Role Overview

We currently operate two SAP environments: a legacy on-premises SAP ECC system supporting U.S. and Canada operations, and a cloud-hosted SAPS/4HANA environment on RISE. With SAP’s end of standard maintenance for ECC and an increasing need for modernization, we are executing a multi-year SAP Modernization Program to consolidate its SAP landscape onto S/4HANA on RISE.

The current phase is focused on the brownfield migration of ECC systems to SAP S/4HANA on RISE, including selective data migration and end-to-end delivery across design, build, testing, deployment, and hypercare. This phase represents a large-scale, integration-heavy effort requiring coordination across multiple value streams, SAP and non-SAP systems, and a System Integrator (SI) responsible for significant portions of delivery.

3. Integration Governance & Issue Management

4. UAT Orchestration (Program-Level)

• Coordination of UAT execution across ~150 business testers
• Define execution framework, schedule, and tracking
• Support QA Leads in coordinating UAT within their streams
• Ensure consistent execution, coverage, and accountability across teams

5. Data, Quality, and Readiness

• Oversee test data strategy, validation, and reconciliation
• Ensure environment readiness and entry criteria across streams
• Drive test asset quality, standardization, and automation readiness
• Provide program-level reporting and go/no-go readiness indicators
• Integrated test strategy and plan
• Program-level UAT execution framework and tracking
• Cross-stream defect triage and reporting
• Test data and validation approach
• Readiness reporting and go/no-go assessments

Experience
