Staff Data Scientist, Performance Marketing

Root was founded on the belief that car insurance is broken, and we set out to change it. We’re harnessing the power of technology to revolutionize this archaic, complicated industry. Using machine learning and mobile telematic platforms, we’ve built one of the most innovative insurtech companies in the world.

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 Staff Data Scientist I on the Performance Marketing team, you’ll lead research on lead segmentation and bidding optimization to boost marketing profitability. You’ll design and execute research programs, expand modeling capabilities, and deliver high-impact solutions into production. As a thought leader, you’ll model best practices and mentor peers in producing rigorous, production-ready work.

This role demands an ownership mentality, with the ability to independently drive work forward, mentor junior team members, and collaborate on large-scale projects. In this role, you will regularly engage with members of cross-functional departments as well as the executive team. Strong communication skills will be an important asset. Join us to push technical boundaries and shape the future of data-driven performance marketing at Root.
