As a Power BI Developer, you are the driving force behind our data visualisation and front-end reporting environment. You translate complex business questions into clear, user-friendly dashboards and semantic models that support better decisions.

Tasks & Responsibilities

BI Development & Analytics Delivery

• Design, develop, and maintain dashboards, reports, and self-service Power BI solutions aligned with business requirements.

• Ensure reliability and usability of BI solutions through model optimisation, refresh monitoring, incident follow-up, and continuous improvement.
• Write advanced DAX formulas and M queries in Power Query for complex calculations and data transformations.

Data Management (Modelling, Integration & Quality)

• Build and monitor data integration pipelines (ETL/ELT), ensuring secure and reliable data delivery from source to reporting layer.
• Implement data quality controls (validation rules, reconciliations, error handling) and contribute to master data consistency.
• Maintain accurate metadata and technical documentation (data lineage, definitions, refresh cycles) to keep data auditable and trustworthy.

Stakeholder Engagement

• Collaborate closely with business stakeholders to refine requirements and ensure successful adoption of BI products.
• Communicate data logic clearly — KPI definitions, lineage, and assumptions — so decision-makers can act with confidence.
• Apply data governance practices: naming conventions, documentation standards, access principles, and retention rules.

Technology & Continuous Improvement

• Stay up to date with BI and data management technologies and propose practical improvements to architecture, tooling, and ways of working.
• Contribute to proof-of-concepts and adoption of new BI capabilities, ensuring maintainability, security, and cost-awareness.
