* Lead the requirements analysis and solution integration for data engineering, ensuring alignment between data strategy, SQL transformation logic, and insights generation.
* Establish and enforce global standards for data modelling, metadata strategy, and lineage to ensure end-to-end data governance and regulatory compliance.
* Advise business and technical stakeholders on best practice data modelling approaches to enable secure, scalable, and exposure-ready data utilisation.
* Manage relationships with senior stakeholders and vendors to ensure architectural decisions support the broader business and technology strategy.
