Senior Marketing Data Scientist

As a Senior Marketing Data Scientist, you're the person who turns marketing data chaos into actionable intelligence. You're building attribution models, customer segmentation algorithms, churn prediction systems, and lifetime value calculations. The senior part means you're also influencing which questions the team should even be asking.

Your day splits between technical work and translation work. You might spend the morning refining a multi-touch attribution model in Python, then present findings to marketing leadership who need to understand implications without understanding the methodology. You need to be fluent in both languages — the statistical rigor that makes your work valid and the business context that makes it useful.

The hardest part is data quality. Marketing data is messy — tracking breaks, attribution windows are arbitrary, and customers touch dozens of touchpoints before converting. You're constantly making judgment calls about what the data can and can't tell you. The people who thrive here are comfortable with ambiguity and can communicate uncertainty without losing credibility.
