Senior Power BI Developer

You’ll work alongside colleagues in the Insights team and partner closely with the Data & Technology function, while acting as the team’s primary Power BI specialist.

We are building a new data platform on Microsoft Fabric and, alongside it, the reporting that Cash Access UK will run on. Your job is to manage that reporting layer end to end: the certified semantic models that sit over the warehouse, the reports built on them, and the standards that determine how Power BI content is developed here.

You will support the design and delivery of the reporting stack from an early stage of BI maturity. This is not a role where requirements arrive fully formed and you build to spec. You will help shape what good looks like here, agree definitions with the people who own the business areas, and help shape how reporting develops as the organisation grows.

• Substantial Power BI development experience, with meaningful ownership of a body of reporting rather than building to someone else’s specification.
• Advanced DAX, including performance tuning, with strong Power Query skills.
• Strong dimensional modelling for analytics, with practical experience of tabular model design.
• Experience implementing row level security and governed sharing across multiple business areas.
• Strong SQL skills, with experience querying analytical data warehouses.
• Experience working to defined workspace, deployment and lifecycle standards, and improving them where they fall short.
• Experience working with source control, deployment pipelines and controlled release processes for Power BI assets.
• A track record of turning vague requirements from non-technical stakeholders into reporting that gets used.
• Comfortable working where process is not yet established, able to set direction and deliver with limited supervision.
• Credible with senior stakeholders, and willing to challenge a request when the underlying question is the wrong one.
