• Defining conformed dimensions, facts, hierarchies, and reference data
• Resolving data conflicts across regions, entities, and legacy systems
• Working closely with Finance and HR stakeholders to validate definitions and structures
• Producing clear, robust data model documentation suitable for long-term use
• Supporting data architects and engineers to ensure accurate implementation

• Extensive experience as a Data Modeller in complex, enterprise environments
• Deep expertise in Finance data modelling (GL, cost centres, entities, reporting hierarchies, actuals, budgets, forecasts)
• Strong exposure to HR data models (employee, organisation, payroll, time, rewards)
• Proven experience working with multiple global source systems
• Strong understanding of data governance, master data, and data quality principles
• Excellent communication skills, able to work directly with senior Finance and HR stakeholders

• High-impact foundational work shaping how global Finance and HR data is structured
• Clear remit focused on modelling quality and long-term sustainability
• Opportunity to influence enterprise-wide data standards
