Senior Power BI Developer

We're looking for an experienced Power BI Developer to join our BI/Data Analytics team, supporting a large-scale enterprise semantic model built on Microsoft Fabric and Snowflake
. You'll work on a mission-critical reporting platform serving sales, labor, attendance, and financial reconciliation across the organization, with a strong focus on performance optimization, data modeling best practices, and scalable report development.

• Design, build, and maintain Power BI semantic models using TMDL and PBIP (Git-integrated) project format — no reliance on manual .pbix-only workflows.
• Develop and optimize DAX measures
  , calculated columns, hierarchies, and relationships across large (multi-GB, 80M+ row) fact tables.
• Implement and maintain incremental refresh policies (rolling window/incremental partitioning) to manage large historical datasets efficiently.
• Diagnose and resolve refresh failures, memory/capacity issues, and performance bottlenecks (Verti Paq Analyzer, DAX Studio, Fabric Capacity Metrics).
• Design and apply surrogate key strategies to reduce model size and improve query/relationship performance on high-cardinality columns.
• Build and maintain Power BI reports following established design/SSA standards (report chrome, slicers, drill-through, bookmarks, conditional formatting).
• Collaborate with data engineering teams on Snowflake/dbt pipelines feeding the semantic model; troubleshoot source-to-model data reconciliation issues.
• Manage deployments across DEV/PROD work spaces via deployment pipelines and Git-based version control (branching, PRs, code review).
• Use Power Shell / REST APIs (Enhanced Refresh API, XMLA endpoint) to automate refresh operations, monitor refresh history, and script recovery/reload procedures.
• Perform root cause analysis on data discrepancies, broken relationships, blank/missing values, and reporting anomalies; document findings clearly for stakeholders.
• Manage Row-Level Security (RLS), workspace/app permissions, and capacity (SKU) planning for Fabric/Premium.
• Partner with business stakeholders to translate requirements into scalable model and report designs; write clear documentation and user stories (Jira/Agile).

• 6+ years hands-on experience with Power BI (Desktop, Service, Premium/Fabric capacities).
• Strong proficiency in DAX and Power Query (M), including complex measures, time intelligence, and native query optimization.
• Deep understanding of semantic model design
  : star schema, relationships, cardinality, Verti Paq storage engine, and performance tuning techniques.
• Experience with incremental refresh
  , large fact table management, and memory/capacity troubleshooting in Premium/Fabric environments.
• Working knowledge of Snowflake (SQL, views, warehouses) and ideally dbt for source data transformations.
• Experience with Git-based Power BI development (PBIP/TMDL format), branching strategies, and pull request workflows.
• Familiarity with Power Shell and Power BI REST APIs for refresh automation and administration.
• Strong analytical and debugging skills — ability to trace issues from report visuals through DAX/relationships back to source data.

• Experience with Microsoft Fabric (Lakehouse, Fabric Capacity Metrics, One Lake).
• Exposure to DAX Studio / Tabular Editor / Verti Paq Analyzer
  .
• Familiarity with Jira/Agile delivery processes.
