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.
