The challenge
We are seeking an Energy Migration Senior Data Analyst to join our Home Services Energy Data Team to assist with the migration of our Energy Portfolio from UW legacy application to Gentrack Junifer.

The migration work will have two parts:

This role will be particularly focussed on (b) above and will include: interpreting Junifer data models, build ETL scripts, and populate energy data models in our UW BigQuery environment.

This role would need:
โข Experience in data migration projects (ideally energy platform migration).
โข Experience in Gentrack Junifer application/ data models.

โข Proficient in SQL as both data extraction scripts and data loading scripts will be sql based.
โข Experience working with Google BigQuery and Dataform environments.
โข Experience in working collaboratively with a multitude of teams to meet the timelines and deliverables.
What youโll do
โข Analyse Gentrack Junifer data models to understand their data structures.

โข Work collaboratively with the wider energy data team to re-model and populate data warehouse data models in UW BigQuery.
โข Work closely with cross-functional teams to understand their data needs and provide relevant analyses.
โข Validate and clean data to ensure accuracy and reliability for analyses.
โข Maintain clear documentation for data processes, transformations, and best practices to ensure long-term maintainability and team-wide understanding.
โข Support the preparation and creation of regulatory reports.
โข Provide technical guidance to those less familiar with Junifer databases and Gentrack architecture, as well as making the most of opportunities to share knowledge and empower others.
