About the role

The Principal – Procurement & AI Delivery is BT Digital's strategic and technical authority for the end-to-end SAP Source-to-Pay (S2P) and Procurement technology estate. This is a principal-level leadership role spanning SAP S/4HANA Procurement, SAP Ariba (now rebuilt as an AI-native platform on SAP BTP), SAP Concur, Sirion CLM, Nnamu, Who Buys What spend visibility, and a growing portfolio of cloud-native and AI-powered procurement tools.

BT manages billions in annual procurement spend across direct and indirect categories, and the Procurement technology estate is the intelligence layer that governs how that spend is sourced, contracted, approved, paid, and optimised. As the world's leading Source-to-Pay platforms undergo their most significant AI transformation in a decade — with SAP Ariba rebuilt from the ground up on SAP BTP with embedded Joule agents, and Sirion CLM recognised as the Gartner Magic Quadrant Leader for the fourth consecutive year — BT Digital needs a Principal who can navigate this landscape with authority and turn SAP and third-party AI innovation into competitive advantage for BT.

This is not a BAU technology management role. It is a transformation leadership position — owning the multi-year Procurement technology roadmap, driving AI adoption across the S2P lifecycle, governing the commercial and licence estate, and building the technical SME capability that BT Digital needs to operate at the frontier of AI-powered procurement.
