Evolve our platform: Partner with other data engineers and platform engineers to improve how we work
Maintain data integrity: Ensure data governance and privacy policies are implemented and enforced across the tens of terabytes of data flowing through systems daily

At a minimum, 4 years of professional experience in data engineering
Proficiency in SQL and Python, and an eagerness to integrate AI into data engineering workflows to help us scale
Experience mapping complex business processes into extensible, analytical data models
Strong software engineering fundamentals
Self directed execution

A track record of recommending and implementing new data collection methods to improve data model quality
You have used data to answer specific questions and guide company decisions
You have experience with cloud distributed systems (we use GCP) including distributed databases, message queues or batch / stream processing
