Nice To Have Experience:

• Experience with CRM and digital marketing platforms (Braze Cordial Google Ads Meta Ads etc)
• Experience with the Snowflake data platform and its streaming/batch components; DBT and Airflow familiarity.
• Background in clickstream data reliability: event taxonomy validation tooling event health monitoring and developer workflows that “shift-left” data quality.
• Familiarity with tracking and SDK ecosystems (e.g. Tracking SDK and “Direct Send”) experimentation and downstream analytics integrations.
• Knowledge of data governance practices and lineage/discoverability platforms like the Data Catalog; exposure to privacy and compliance workflows (e.g. CCPA/CPRA).
• Experience operating services on Kubernetes (EKS) GitOps/ArgoCD and adopting paved-path CI/CD patterns on CircleCI.
