- Advanced proficiency in SQL and in either Python or R for data manipulation, statistical analysis, and modeling.
- Hands-on experience designing and analyzing marketing experiments (e.g., A/B tests, geo experiments, holdouts) and applying causal inference techniques to estimate incrementality.

- Experience building business-facing dashboards and self-serve tools in Looker, Tableau, or Mode.
- Experience working with modern data warehouses (e.g., Snowflake, BigQuery, or Redshift) and version control (Git).
- Demonstrated ability to translate ambiguous business questions into analytical roadmaps and to communicate clear, actionable recommendations to non-technical and executive audiences.

- Experience with analytics engineering and pipeline tooling (e.g., dbt, Airflow) and strong data QA practices.
- Background in lifecycle/CRM analytics (e.g., uplift modeling, audience selection, message experimentation) and LTV forecasting.
- Exposure to experimentation platforms and feature flagging (e.g., Optimizely or internal frameworks) and to ML applications for bidding, pacing, and creative optimization.
- Experience mentoring peers and elevating analytical standards through code reviews, reproducible research, and documentation.
