• Develop governed lakehouse solutions using Delta Lake, medallion architecture and Unity Catalog.
• Own Power BI semantic models, DAX measures and row-level security, ensuring reporting is accurate, secure and performant.
• Translate marketing and contact-centre requirements into clearly defined metrics and actionable reporting.
• Modernise legacy processes and improve reliability, data quality and maintainability.
• Work with senior stakeholders to clarify requirements, explain trade-offs and recommend solutions.
• Strengthen engineering practices through testing, documentation, Git and CI/CD.
• Mentor colleagues and share good practice across the team.

What you’ll bring

• Strong production experience with Databricks, PySpark, Delta Lake and Unity Catalog.
• Hands-on Power BI expertise, including data modelling, DAX, RLS and performance optimisation.
• Strong SQL skills and experience with Azure data services.
• Experience supporting contact-centre operations and/or performance marketing.
• Confidence defining and validating measures such as lead conversion, acquisition costs, attribution, agent performance or service levels.
• A track record of independently owning delivery, resolving complex problems and introducing improvements.
• Clear communication and the confidence to constructively challenge requirements and existing approaches.
• Experience of Microsoft Fabric would also be useful.
