Maintain a configuration register documenting all setups, change decisions, and rationale to support audit readiness and knowledge continuity.

Champion standard Oracle functionality over customisation; document justification where deviations are approved.

Conduct impact assessments for each quarterly release, identifying configuration, integration, and reporting changes that may affect live operations.

Lead and document regression testing across key finance cycles (P2P, O2C, R2R, Fixed Assets, Project Costing/CVR inputs) and HCM processes.

Manage go‑live readiness sign‑off, stakeholder communications, and post‑update hyper‑care, including rapid triage of any defects introduced by the update.

Scope, document, and maintain integrations via Oracle Integration Cloud (OIC) across HRFinance, procurement, supplier portals, bank feeds, payroll, and BW/BI reporting feeds.

Own interface controls and monitoring; proactively identify and remediate data defects, reconciliation breaks, and mapping errors before they impact business users.

Maintain data standards and reference data for projects, cost codes, suppliers, and workforce records; enforce data governance and lifecycle management policies (including GDPR and retention requirements).

Provide 2nd‑line functional support and triage for Oracle Fusion incidents and change requests; manage Oracle Service Requests (SRs) through to resolution.

Act as the primary liaison with the Managed Service Provider (MSP) for day‑to‑day fixes, enhancements, and release validation.

Ensure clear, timely communications to end users on system changes, incidents, and planned‑maintenance windows.

Partner with Finance Controls and Internal Audit on access management, Segregation of Duties (SoD), approval hierarchies, and year‑end audit readiness.
