• Embed strict internal controls for audit logging, data refresh auditing, and change tracking per OIT and program compliance standards.

Performance Engineering and Reliability:

• Optimize dataset size, entity relationships, and measure logic by utilizing composite models, aggregations, and Incremental Refresh where appropriate to strictly meet agreed-upon service levels;
• Target, monitor, and continuously improve report render times and dataset refresh performance to adhere to defined service level agreements (SLAs);
• Collaborate with the Data Warehouse team on distributed processing choices that directly impact Direct Query, Direct Lake, and Import modes to ensure optimal capacity utilization and cost-efficient infrastructure management.

Deployment Lifecycle and DevOps:

• Use Power BI Deployment Pipelines and Azure DevOps for versioning, environment promotion Development and Production (DEV/PROD), approvals, and rollback strategies; and
• Automate refresh schedules, key vault secrets, service principals, and Continuous Integration and Continuous Delivery (CI/CD) checks consistent with OIT change and incident management processes.

Collaboration and Stakeholder Engagement:

• Publish workspace governance guides, report accessibility standards, and User Acceptance Testing (UAT) scripts consistent with OIT documentation frameworks;
• Contribute to the enterprise data catalog in Microsoft Purview and to SharePoint knowledge bases with versioned artifacts linked directly to Correctional Information Management System (CIMS) datasets and interfaces.

Required Qualifications:

• A minimum of five (5) years of experience in business intelligence or analytics, including three (3) years building Power BI solutions at an enterprise scale;
• Expert DAX and strong Power Query and M skills syntax, backed by deep tabular modeling experience and Structured Query Language (SQL) proficiency across complex datasets;
