• Design a repeatable migration factory: templates, accelerators, mapping spreadsheets, and conversion playbooks for Informatica dbt.


• Oversee conversion, unit testing, and parallel runs to validate that dbt models match legacy outputs (row counts, aggregates, business rules).


• Lead hands‑on development of dbt models, seeds, snapshots, tests, macros, and documentation.


• Define and implement testing strategy using dbt tests (schema tests, data tests, custom tests) and integrate with broader data quality checks.


• Set up and maintain dbt environments (dev/test/prod), profiles, and connections to Snowflake on Azure.


• Introduce and enforce code quality practices.


• Code reviews & pull requests


• Modular, reusable models and packages

Minimum Skills Required:

• 8+ years total experience in Data Engineering / ETL / Data Warehousing.
