The Senior Data Analyst leads the analyses behind the business's hardest questions and owns the health of the reporting estate.

• Expert SQL on large datasets.
• Data modelling literacy: reads and navigates star schemas and gold models.
• Dashboard craft in Databricks AI/BI dashboards or an equivalent modern BI tool, plus deep Power BI for the legacy estate: semantic models with storage modes, relationships and security passthrough, no business logic in the tool, and report lifecycle governance.

WHAT YOU WILL BE DOING?

• Design and run the analyses behind high-stakes decisions, using sound statistical method, driving business impact.
• Lead the framing of ambiguous business problems into testable questions with senior stakeholders so that analysis effort lands where value is.
• Set and maintain analytical and visual standards, covering methods, documentation, certified sources, semantic-model and lifecycle rules, so that quality does not depend on individuals.
• Lead usage-based rationalisation across Power BI, Grafana, and the mapping of legacy SAP BW reports to gold replacements, so that the estate shrinks to what is used.
• Mentor junior and intermediate analysts through review and pairing, and coach business users in guarded self-service, so that capability grows.

WHO YOU ARE?

• Structures ambiguous questions into testable analysis.
