Job Description: We are seeking a Senior BI Engineer based in Latin America to own the development and evolution of our Microsoft Fabric semantic model layer, and drive the creation of high-quality, performant Power BI reports for our Starbase project. You will work hands-on with Lakehouse/Warehouse, the SQL analytics endpoint, and the Power BI Service, applying best practices for dimensional modeling, SQL, DAX, and CI/CD in Fabric. The ideal candidate is fluent in semantic model design, Direct Lake, and performance tuning. Experience with Power BI is a plus, but not required. Responsibilities : Design and maintain star‑schema semantic models (facts, dimensions, role‑playing dimensions, SCD patterns). Define relationships, hierarchies, calculation groups, KPIs, and reusable business logic in DAX. Select and tune Import, DirectQuery, Direct Lake (and Hybrid tables/Incremental Refresh when needed). Optimize with aggregations, partitioning, column sizing, and the Performance Analyzer. Build models on Lakehouse/Warehouse (incl. SQL analytics endpoint), Dataflows Gen2, and external sources; configure gateways for on‑prem data. Implement Row‑Level Security (RLS) and Object‑Level Security (OLS); manage Build permissions, endorsements (certified/promoted), and sensitivity labels in partnership with data governance. Use Power BI Projects (PBIP), Git integration and deployment pipelines for versioning and multi‑environment releases; serialize models with TMDL and use external tools where appropriate. Monitor and right‑size Fabric capacity using the Capacity Metrics app; collaborate with admins to keep models and refreshes healthy. Document definitions, lineage, and refresh behaviors; evangelize reuse of the semantic layer across workspaces. Qualifications Experience: 6+ years of experience building production ETL/ELT pipelines. Strong Power BI modeling experience with dimensional/ star schema design, and strong DAX and Power Query (M). Hands‑on experience with Microsoft Fabric (Lakehouse/Warehouse, SQL analytics endpoint, OneLake concepts). Proven use of Direct Lake plus Import/DirectQuery and a clear understanding when/why to use each. RLS/OLS design and implementation experience. PBIP + Git and deployment pipelines for CI/CD; TMDL familiarity (preview features acceptable). Performance tuning (VertiPaq fundamentals, partitions, aggregations; Performance Analyzer). Comfortable with SQL. Familiarity with TMDL, external tools (e.g., Tabular Editor, DAX Studio) Soft skills: Execution-First Mindset — delivers working functionality quickly, then iterates. Curious Integrator — enjoys untangling messy, niche data feeds and brings order. Quality Advocate — insists on tests, logging, and clear hand-offs. Collaborative Communicator — explains decisions to peers and stakeholders. Continuous Learner — keeps abreast of Azure & Fabric feature releases. Bonus skills: Experience with XMLA endpoint and external tools (Tabular Editor, DAX Studio) is a plus. SemPy / Semantic Link to collaborate with notebooks and data science, or to validate models programmatically. Experience with the Fabric Capacity Metrics app and workspace monitoring. Knowledge of Analyze in Excel patterns and enterprise Excel connectivity to semantic models. XMLA endpoint usage and model lifecycle management with external tools.
