Position Overview

Halvik is seeking BI Developers to support a high-visibility federal data modernization program at the U.S. Department of Transportation. 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 Lakehouse platform.

This is a hands-on execution role within a high-volume report conversion effort. The BI Developer will convert legacy reports into Tableau workbooks and dashboards by following an established, repeatable conversion process. The BI Developer will perform the conversion following documented step-by-step procedures, with the work adhering to defined templates and quality standards established by the senior technical lead.

The ideal candidate has foundational Tableau development skills, solid SQL proficiency, comfort working with AI-assisted development tools, attention to detail, and the ability to execute a defined process consistently and at volume. This role offers significant exposure to Databricks, modern cloud data platforms, and AI-augmented development workflows.

Core Responsibilities

Execute the established report conversion process - either refining pre-generated Tableau report scaffolds or performing manual conversion following documented procedures.

• Build, modify, and publish Tableau workbooks, dashboards, calculated fields, filters, and parameters following established templates and naming conventions.
• Apply performance best practices (context filters, extract optimization, data source filters) under senior developer guidance.
• Handle template-conforming reports independently. Escalate complex reports to the Senior BI Developer for input and guidance.
• Validate converted report outputs, confirm source-to-target fidelity, and troubleshoot discrepancies.
• Perform QA self-checks using established validation checklists.
• Navigate Databricks workspace to locate tables, review schemas, and understand how the medallion architecture feeds Tableau data sources.
• Escalate data-layer issues such as schema changes, transformation errors to Data Engineers with clear documentation of the issue and its report impact.
• Use approved AI/LLM tools to accelerate SQL writing, documentation, data exploration, and troubleshooting.
• Document report logic, conversion decisions, validation results, and discrepancies clearly and consistently in project tracking tools.
