• Build and optimize trusted, analysis-ready datasets using SQL, PySpark, and modern data modeling practices.

• Apply best practices in Power BI development, including DAX optimization, dimensional modeling, workspace governance, security, and performance tuning.

• Define and enforce semantic modeling standards for scalability, usability, and consistency across BI solutions.

• Optimize large-scale datasets using techniques such as Direct Lake, incremental refresh, and partitioning where appropriate.

• Prepare data for AI and Copilot-enabled analytics experiences by simplifying schemas, setting up verified answers, and authoring domain-specific instructions.

• Design and support Fabric-based analytics and agentic experiences that enable governed, natural-language access to curated business data.

• Implement strong engineering practices, including version control, CI/CD, testing, documentation, and support for production BI assets.

• Partner effectively with business stakeholders, data engineers, data scientists, and technology teams to define requirements, deliver solutions, and drive adoption.

Success in this role:

• Improve the performance, scalability, and usability of enterprise BI solutions.

• Increase adoption of governed semantic models and self-se
