• Architect and implement sophisticated data models in our Snowflake data warehouse, transforming raw data into clean, business-ready tables that serve as the single source of truth.

• Collaborate on impactful business projects, working closely with stakeholders across Sales, Marketing, and Product to understand their needs and deliver data solutions that drive strategic decisions.

• Power our customer-facing analytics, developing and exposing data within the GitGuardian product to provide our users with valuable insights.

• Champion data quality and governance across the organization, establishing best practices and ensuring the integrity of our data assets.

• Mentor and guide other engineers, sharing your expertise and contributing to the continuous improvement of our team's skills and processes.
