This role will play a critical part in improving the quality, consistency, and reliability of HR data across Workday, Legacy HR systems, finance platforms, and local country data sources.

Workday expertise - Strong hands-on experience with Workday HCM data structures, reporting, and HR master data management.

HR Data Quality & Reconciliation - Extensive experience analysing HR master data across Workday, Legacy HR systems, finance systems, and country-level sources to identify mismatches, duplicates, and inconsistencies.

Root Cause Analysis - Proven ability to investigate recurring data issues and define sustainable corrective actions across global datasets.

Data Quality Frameworks - Experience defining and implementing data quality rules, validation checks, and KPI frameworks across HR data domains.

Governance & Stewardship - Strong understanding of data governance, ownership models, and global data stewardship across multi-country environments.

Reporting & Dashboards - Ability to design and deliver Workday reports and dashboards covering data quality, audit findings, remediation progress, and KPI tracking (low/medium/high severity).

Stakeholder Engagement - Partner with HR, Finance, Technology teams, and country-level data stewards to translate audit findings into actionable remediation plans.

Issue & Remediation Tracking - Build and maintain structured issue logs and remediation backlogs, including ownership, severity, status, and resolution tracking.

Business Requirements Gathering - Capture and translate requirements from non-technical stakeholders into clear Workday reporting and data specifications.

Compliance & Audit Support - Ensure all reporting, data definitions, and reconciliation logic are fully auditable and aligned with governance and compliance standards.

This is an excellent opportunity to work on a high-impact global programme, helping to shape and stabilise Workday as the organisation's single source of truth for HR data while driving measurable improvements in data quality, governance, and reporting.
