Responsibilities

Lead the technical migration from legacy SQL Server stored procedures and ADF pipelines to Databricks Lakehouse (Delta Lake), ensuring best practice Lakehouse design.
Translate traditional relational data warehousing paradigms into scalable, distributed Lakehouse frameworks (Bronze, Silver, Gold).
Design robust, reusable ETL/ELT frameworks using PySpark, Delta Live Tables (DLT), and Databricks Workflows.
Architect and refine the Gold Layer (dimensional models, star schemas) specifically to maximize Power BI performance.
Optimize Databricks SQL Warehouses to support high-concurrency, low-latency Power BI queries (DirectQuery and Import modes).
Implement advanced optimization techniques, including Z-Ordering, data skipping, liquid clustering, and materialized views.
Define and enforce governance standards for cluster sizing, auto-scaling policies, and serverless SQL compute to balance performance with cost.
Implement proactive monitoring dashboards to track Databricks Unit (DBU) consumption and identify cost-saving opportunities.
Establish best practices for partition strategies and file size management within Delta Lake.
Design and implement a robust data security model using Unity Catalog for centralized governance.
Enforce row-level and column-level security policies to ensure compliant data access for Power BI consumers and internal analysts.
Align the Lakehouse security architecture with existing enterprise Azure Active Directory standards.
Act as the primary technical lead, conducting dedicated pair-programming sessions, workshops, and code reviews to transition the team from SQL-centric to Spark-centric thinking.
Create comprehensive technical documentation, including architecture diagrams, design patterns, and optimization playbooks.
Build a foundational knowledge transfer framework to ensure the internal team is fully self-sufficient post-migration.
Communicate effectively verbally and in written form to both technical and non-technical audience.
Work in an organized fashion, completing tasks timely while paying close attention to details.
