This program is migrating a large-scale legacy reporting environment - comprising several thousand reports - from Oracle Data Warehouse / OBIEE into Tableau dashboards connected to a Databricks platform., This is a senior hands-on delivery role. The Senior BI Developer will design and maintain the repeatable conversion process used to transform legacy report definitions into Tableau workbooks and data sources. A significant part of this process leverages AI/LLM-generated starting points - structured report scaffolds derived from parsed OBIEE metadata - which the Senior BI Developer will review, validate, correct, and refine before reports are published. For complex reports that resist automated conversion, the Senior BI Developer will perform Tableau development against Databricks gold-layer tables., * Maintain and refine the repeatable report conversion process - covering both the LLM-assisted path and structured step-by-step conversion from legacy logic to Tableau. * Review and correct LLM-generated Tableau reports. * Define validation criteria and quality gates for each conversion path. Review and approve junior developer output before reports advance to QA and UAT. * Design Tableau data sources (TDS) that correctly handle complex data structures, including join strategies. * Develop complex Tableau workbooks, dashboards, table calculations against Databricks gold-layer tables. Own performance tuning and connection strategies. * Collaborate with Data Engineers on gold-layer table design and Unity Catalog for data governance, metadata management, and access control. * Identify reusable report templates and patterns across the report catalog. Codify these as standardized templates that junior developers can apply at volume. * Work with and refine AI/LLM tools as part of the conversion workflow. * Serve as the technical authority on report fidelity for complex and high-risk reports. * Mentor junior BI Developers, contribute to migration playbooks and knowledge transfer documentation, and participate in stakeholder demos and Agile ceremonies. ## Related Videos - [Enjoying SQL data pipelines with dbt](https://www.wearedevelopers.com/videos/823-enjoying-sql-data-pipelines-with-dbt) - [JavaScript?
