## Description

Our client seeks a Senior Data Engineer to own the governed transformation layer end-to-end. The role will design and build Snowflake transformation layers, migrate legacy SQL views and user-maintained dimensions into versioned, tested dbt models with lineage, and define conformed dimensions and operational facts to unify multi-ERP environments. The position will establish modeling, testing, naming, documentation, and CI/CD standards. The work is hands-on with dbt, SQL, and Python., * Design and build the Snowflake transformation layer from raw to staging to conformed to marts as the governed foundation for reporting and AI/ML.

 * Migrate existing SQL views to versioned, tested dbt models with full lineage.
 * Define conformed dimensions and operational facts across multi-ERP environments using Kimball principles including star schemas, surrogate keys, fact grain, and SCD Type 1 and Type 2.
 * Set standards for modeling, testing, naming, documentation, CI/CD, Git workflows, code review, dbt project structure, model contracts, and release management.
 * Partner with report owners to validate semantic equivalence and minimize disruption during BI cutovers.
 * Define and own the semantic layer across Snowflake, dbt, and Power BI to ensure consistent metrics.
 * Implement data quality testing, observability, and lineage with dbt tests and equivalent tools, partnering with IT Audit on SOX-relevant controls.
 * Design models for AI/ML and agent readiness with stable keys, clear semantics, and metadata for LLM retrieval and tool use.
 * Collaborate with AI/analytics teams on feature-table patterns, golden-record exposure, and data foundations for agentic applications.
