Translate business definitions into tested technical implementations. Build reusable semantic models for BI tools and AI agents. Develop and maintain dashboards and analytical products for internal teams. Reconcile critical metrics across operational systems, reporting, and finance. Build automated tests for metrics and business rules. Establish documentation, metadata, and lineage around business definitions. Help establish the data-standardization process between business, Data & AI, and Platform Engineering. Key Requirements Strong analytics engineering or data modeling background. Excellent SQL skills. Experience with modern transformation frameworks such as dbt or equivalent. Strong understanding of dimensional, canonical, and semantic modeling approaches. Experience building production BI and analytical products. Experience defining metrics jointly with non-technical stakeholders. Strong understanding of data testing and reconciliation. Ability to translate ambiguous business concepts into precise definitions. Excellent communication skills. Nice to Have Experience implementing semantic layers or metrics layers.
