GSC ERP PMO​/Cutover Lead Secondment

The supply chain is not just core to GSK operations; it's vital to bringing our innovations to patients as quickly, efficiently and effectively as possible. Technology is transforming how we manufacture medicines and vaccines, enabling us to increase the speed, quality and scale of product supply. Aligned to industry peers, GSK has embarked on a large-scale global transformation - ERP Evolution Program.

To achieve the outcome of the ERP Evolution programme, an S4/HANA ERP solution will be deployed globally via complex waves across GSK's Pharma and Vaccines businesses to commercial markets, manufacturing sites, R&D, all shared financial services, and additionally GSK's customers, suppliers and logistics partners. The Wave 0 scope comprises a representative subset of GSK's business across the Pharma and Vaccines sectors, including global supply and financial functions.

The successful delivery of Wave 0 is essential, as it will establish the foundation for all subsequent waves. Wave 0 will demonstrate the programme's methodology, validate the cutover orchestration, and enable downstream waves to scale effectively while meeting all regulatory and business‑continuity requirements.

GSC PMO Cutover Lead will be accountable for leading the end-to-end business cutover activities for Global Supply Chain deployments, ensuring a controlled and seamless transition to the S/4

HANA ERP platform. It will coordinate internal GSK stakeholders, GSK 3rd‑party providers to deliver cutover execution in line with agreed timelines, while safeguarding business continuity and operational readiness. The Cutover Lead will provide structured PMO delivery support to Wave 0 Implementation Lead including status reporting, RAID ownership support, risk and dependency management. It will drive the prioritization, resolution and escalation of Hypercare incidents to ensure timely and effective issue management as well as monitor and address any issues that arise during the cutover process to ensure a smooth transition post go‑live.
