For a leading organisation in the energy / utilities sector, we are looking for a freelance Power BI Expert.
The Group Controlling department is rolling out a set of Performance Indicators across the group's entities. KPIs are cascaded from strategic to operational level and visualised through automated Power BI dashboards.
As Power BI Expert, you will be the go-to person to design, automate, optimise and maintain the reporting landscape that supports these initiatives. You make sure that all stakeholders — from executives to operational teams — get the right insights at the right time, in a way they can trust and act upon.
Key responsibilities
KPI reporting & automation
- Build and automate end-to-end KPI reporting for Group Controlling stakeholders.
- Translate business questions into clear, decision-ready dashboards aligned with the performance framework.
Maintenance & continuous improvement
- Support the maintenance of the existing Group Controlling Power BI portfolio.
- Monitor adoption and usage (e.g. via Power BI Usage Metrics) and proactively propose improvements based on real user behaviour.
Semantic models, visualisation & data quality
- Rationalise the Power BI semantic models: consolidate overlapping datasets, clarify ownership, document relationships and improve refresh performance.
- Optimise visualisations: simplify, standardise and align them with design and accessibility guidelines so reports are intuitive and consistent across the portfolio.
- Lead data cleaning and data quality activities upstream of the reports, in close coordination with data owners.
Bridge role between Business and IT
- Act as a trusted advisor to business stakeholders (Controlling, IT and other departments), turning sometimes fuzzy needs into concrete reporting solutions.
- Engage with IT and Data teams on databases, dataflows, gateways and Power BI governance (workspaces, roles, access).
Your profile
- Solid hands-on experience with Power BI Desktop (semantic models, DAX, Power Query, workspaces, apps, dataset refreshes, gateways).
- Proven experience designing, automating and maintaining KPI dashboards in a corporate or group-wide context, ideally in Controlling, Finance or IT governance.
- Strong skills in data modelling, semantic model optimisation and data cleaning (performance tuning, naming conventions, documentation).
- Ability to work autonomously: identify needs, propose solutions for both data structure and visualisation, and drive them to delivery.
- Excellent communication skills, comfortable talking to both business stakeholders (controllers, managers, executives) and IT/Data engineers.
- Fluent in English; a good working knowledge of French and/or Dutch is a strong asset, German is a plus.
