Are you a Power BI Developer who genuinely cares about building beautiful, intuitive, high‑impact dashboards? I’m hiring for a Power BI specialist at a major multi‑brand group with a centralised data function that works across digital, creative, technology, and customer‑facing teams. This is a role for someone who lives and breathes Power BI – modelling, DAX, UX, and storytelling.

You’ll work across a wide range of business areas and stakeholders, translating ambiguous briefs into real, meaningful dashboards that teams actually use. It’s a highly visible, design‑centric role where quality really matters.

What you’ll be doing

• Designing and building Power BI dashboards to an exceptional standard of visual design and user experience.
• Developing robust data models using star schema principles, setting up relationships, hierarchies, and optimised structures.
• Writing efficient, clean DAX – including complex measures and time intelligence.
• Using Power Query (M) to build transformations and shape data inside Power BI.
• Establishing and managing consistent design systems, templates, and themes across reports.
• Leading scoping conversations to translate unclear or ambitious requests into clear dashboard requirements.
• Producing wireframes and mock‑ups to align design direction prior to build.
• Auditing and improving existing reports for performance, maintainability, and UX.
• Documenting models and dashboards clearly for long‑term maintainability.
• Managing deployments, workspaces, and pipelines in Power BI Service.

What you bring

Must‑haves:

• Strong, demonstrable Power BI development experience – you’ll need a portfolio or examples of your work.
• Deep understanding of data modelling, star schema, relationships, and model optimisation.
• Advanced DAX (complex measures, performance optimisation).
• Strong Power Query (M) capabilities.
• Ability to translate complex data into clear, actionable narratives through dashboard structure and design.
• Confidence in client‑facing or stakeholder‑facing conversations, scoping requirements, and pushing back constructively.
• Experience building maintainable, scalable, and high‑quality Power BI solutions.

Nice to have:

• Experience with Tableau or Qlik.
• Familiarity with DAX Studio or Tabular Editor.
• Understanding of accessibility best practice in dashboard design.

Note:
The business does not require marketing analytics experience for this version of the role – the priority is powerful Power BI development and design expertise, not domain experience.

Why this role

• Work with a highly respected centralised data team supporting multiple brands and functions.
• Big focus on design quality – the team genuinely cares about UX, storytelling, and building dashboards people love.
• Strong support from senior leaders and exposure to high‑profile projects across the wider organisation.
• Join during a period of growth with opportunities for progression and technical development.
