SAP Technical Lead

This position is within the Business Services Team and is part of the Corporate Branch. The SAP Technical Lead is a senior technical authority responsible for guiding the Digital Transformation Agency (DTA) through the implementation of a SAP S/4HANA Cloud-based ERP solution. The SAP Technical Lead provides high-level technical oversight and governance during the ERP mobilisation and implementation phase to ensure robust, secure, and fit-for-purpose outcomes.

The primary purpose of this role is to bridge the ERP/SAP BAU technical capability gap during the initial phases of the project, complement (not duplicate) the Systems Integrator (SI), and establish internal technical continuity that will facilitate a smooth transition to a sustainable business-as-usual (BAU) support model post-implementation.

Key duties

• Lead technical delivery for SAP S/4HANA mobilisation and early implementation (platform setup, access, integrations, enablement). Act as primary technical contact, resolve issues, and provide hands-on support until SI and BAU are established.
• Define and govern end-to-end SAP S/4HANA architecture, ensuring alignment with fit-to-standard, clean core, AGA ERP Standards, and government ERP approach. Leverage SAP BTP for extensions and minimise core customisation.
• Govern integration design between SAP S/4HANA and legacy/external systems (incl. Entra ID), ensuring API-first, secure, high-performance solutions aligned to enterprise and interoperability standards via SAP Integration Suite.
• Oversee data migration planning, quality, and execution with SDO and SI. Validate readiness, reconciliation, and completion of migration activities (e.g. Migration Cockpit).
• Lead testing oversight (unit, integration, UAT, parallel run), ensure delivery of test artefacts and readiness reports, and provide expert input into go-live decisions based on risk and quality evidence.
• Embed security and compliance (ISM, PSPF, data residency) into all technical decisions. Coordinate SI inputs (e.g. IRAP, data flows) to support ATO/accreditation.
• Manage SI technical deliverables, ensuring quality, standards, and timelines. Lead governance forums (e.g. Design Authority), enforce reuse/adopt principles, and oversee vendor performance and risk escalation.
• Provide technical advice to leadership, translating risks (integration, security, data, clean core) into business impacts. Identify, track, and mitigate ERP program risks.
• Oversee SI knowledge transfer, documentation, training, and handover to BAU. Support capability uplift, resolve complex issues, and ensure sustainable post–go-live operations.

This vacancy will be filled on a non-ongoing basis for 12 months, with the possibility of an extension.
