  • Diagnose and tune report/model performance (query folding, VertiPaq analysis, aggregations); troubleshoot data quality issues.
  • Write robust SQL; integrate with Azure data services (e.g., ADLS, ADF, Synapse/Snowflake connectors) and enterprise security standards.
  • Produce documentation, handover materials, and training; participate in Agile ceremonies and collaborate with data engineers/Tech BAs.



Requirements


About you:
  • 10+ years in Business Intelligence/Analytics, 6+ years hands-on Power BI

If you are passionate about transforming data into insights and want to work on projects that truly make a difference, we would love to hear from you. Apply now and become apart of the Bi3 journey, where your skills power smarter decisions.
