Principal Data & BI Engineer

A fast-growing global organisation is looking for an experienced Principal BI Engineer to play a key role in its transition from a SQL Server-led environment to a modern, scalable data platform built around Azure Databricks and Python.

This is not a traditional reporting role - You'll work across the full data and BI lifecycle, owning complex solutions from initial stakeholder engagement and requirements gathering through to pipeline development, data modelling, semantic layers and Power BI delivery.

You'll have the opportunity to:
·Design and build production-grade pipelines using Azure Databricks, Python, PySpark and SQL
·Develop scalable Lakehouse architecture using Delta Lake and Unity Catalog
·Build data and BI products from scratch and own them through to implementation
·Connect marketing, sales and operational data to create a complete view of performance
·Establish consistent KPI definitions and a trusted version of the truth
·Influence senior stakeholders and help raise engineering standards across the team
·Use AI tools such as Claude and OpenRouter to support development, code review and documentation

·Strong production experience with Azure Databricks
·Advanced Python, PySpark and SQL skills
·Advanced Power BI, DAX and data-modelling experience
·Experience building and owning complex data or BI solutions end to end
·Confidence translating ambiguous requirements into reliable, maintainable products
·Strong domain experience in either performance marketing analytics or contact-centre operations, with an understanding of the data and KPIs that drive commercial performance
·Microsoft Fabric experience would be a bonus
