OrganisationPMOPurpose of Role The S4+ Tech Lead is accountable for the end-to-end technical delivery of the S4+ solution across SAP S/4

HANA core, environments, landing zones, infrastructure, SAP RISE, technical tooling and the wider SAP and non-SAP ecosystem in confirmed programme scope.

The role acts as the single-thread accountable owner for technical execution, ensuring that technical delivery is planned, governed, built, tested, cut over and transitioned into support in line with agreed architecture principles, Clean Core standards, SAP Activate gates and programme milestones.

The S4+ Tech Lead works closely with the Integration Lead, Tooling SME, Data, Security, Infrastructure, Environment and Testing teams to ensure specialist technical areas are coordinated as part of one integrated delivery plan. The Integration Lead remains accountable for integration architecture, integration patterns, interface design assurance and integration delivery coordination; the Tech Lead ensures integration activity is aligned to the wider technical plan, dependencies, readiness criteria and programme governance.

The role coordinates activity across Deloitte, SAP, Weir technology teams, BAU support teams and third-party vendors, ensuring technical ownership boundaries are clear across design, build, test, cutover, hypercare and transition to BAU.A critical part of the role is ensuring that technical solutions are right for Weir — sustainable, supportable, secure, operable and aligned to the target operating model — rather than reflecting supplier preference, legacy complexity or localised ways of working.
