The Opportunity

We believe that a disruptive insurance company must have a principled quantitative framework at its foundation. At Root, we are committed to the rigorous development and effective deployment of modern statistical machine learning methods to problems in the insurance industry.

At Root, the Quantitative Science team owns the majority of all marketing capital allocation, using quantitative methods to test, maintain, and enhance our marketing strategies across numerous distribution channels. As a Senior Data Scientist on the Growth team, you’ll help deepen Root’s brand presence by building the measurement and experimentation infrastructure needed to grow our mid- and upper-funnel marketing.

You’ll develop causal frameworks, predictive models, and tools to link brand investment to business outcomes like quote starts, binds, and lifetime value. This role is R&D-heavy, focused on high-uncertainty problems with delayed feedback loops. You’ll also contribute to brand tracking and survey research, help set measurement standards, and advise stakeholders on interpreting results and allocating spend.

Root is a “work where it works best” company, meaning we will support you working in whatever location that works best for you across the US. We will continue to have our headquarters in Columbus to give more flexibility and more choice about how we live and work.
