• Optimise performance of datasets and pipelines (e.g. incremental refresh, query folding, aggregations)
• Conduct data audits to improve quality, security, and governance
• Maintain clear documentation of data flows, lineage, and transformations
• Provide technical leadership across reporting projects and manage stakeholder relationships

• Strong hands-on experience with Microsoft Fabric (Pipelines, Dataflows Gen2, Lakehouse, OneLake)
• Advanced Power BI skills (report design, DAX, Power Query, dataset management, governance)
• Solid understanding of data modelling principles, including star schema design
• Strong SQL skills with a focus on performance optimisation
• Experience with ETL/ELT processes and data transformation workflows
• Knowledge of data warehousing concepts and architectures
