Job description

Description

AI has the potential to transform how insurers bring new products to market. Help us make sure it does. US Data Science (USDS) is building a new team that will use advanced AI to bring our pricing programs to market faster, and we are hiring three senior data scientists to help launch it. The team will build state-of-the-art evaluations for AI and agentic systems. Those evaluations tell us how much value the AI delivers, how accurate it is, and what the risk is when it gets something wrong, so we can move high-value applications into production with confidence. This is a new, highly visible team, and its work will shape how AI is used in the core pricing work of US Retail Markets (USRM). Each of the three roles reports into the Rollout AI team in USDS and has a dotted-line relationship with one of our lines of business: Property & Specialty, Auto, or Small Commercial.
