Were collaborative pragmatic and we value moving fast by fixing the right problemsnot over-engineering but building to last!

The team is made up of three functions:

Data Platform Engineering: Building and scaling ELT pipelines managing data infrastructure on GCP and creating the foundation for analytics and ML feature stores. Youll be part of a small high-performing team of platform engineers focused on reliability scale and developer velocity.

Analytics Engineering: Transform raw data into trusted models using DBT and SQL powering self-serve analytics and business intelligence for stakeholders across the company.

Data & Business Intelligence:
Build dashboards partner-facing reports and insights that drive business decisions and revenue outcomes.

What youll get to do in the role:

• Design build and maintain resilient data pipelines that ingest data from Azure SQL SaaS platforms and event streams into Big Query.
