SENIOR BI ENGINEER WANTED!

We are Upstart 13.

We’re all about delivering value and doing big things. We have become a game-changer for teams around the world who look to Upstart’s services as a differentiator.

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.
• Experience deploying models in hybrid (cloud/on-prem) environments.
• Building Power BI reports is a plus.
