  • Implement security and governance (e.g., RLS, workspace structure, naming conventions, documentation standards)
  • Optimize DAX and Power Query (M) for incremental refresh, and efficient dataset design
  • Validate end-to-end data accuracy with robust testing plans

  • Hands-on experience with Power BI (data modeling, DAX, Power Query) and solid SQL skills
  • Understanding of ETL/ELT concepts, dimensional modeling (star/snowflake), and the BI lifecycle
  • Familiarity with data governance (RLS, documentation, naming/versioning) and dashboard UX
  • Strong analytical thinking, problem-solving, and communication skills
  • ability to collaborate with both business and technical audiences
