  • At least 7 years of progressive experience in data science, marketing science, or advanced analytics, with models directly influencing marketing investments or product growth.
  • Deep practical expertise in media mix modeling, incrementality testing, geo-testing, multi-touch attribution, causal inference, and client lifetime value or propensity modeling is required.
