The Specialty Product Design and Modeling Team is the team behind the science of pricing for Liberty Mutual's Specialty Lines products (Landlord, Umbrella, Condo, Renters, Specialty Vehicles). Using advanced predictive analytics and statistical modeling, we build and refine rating programs that drive profitable growth. But we're more than a modeling team. We shape strategy, decide which variables matter, source the best data, and design rating programs that give Liberty Mutual a genuine competitive edge.

The Director II, Data Science is a frontline manager role reporting to the Specialty Senior Director and will be responsible for the following:

Frontier Program Representation Liberty Mutual is transforming US Retail Markets Personal Lines onto a modern Unified Insurance Platform (UIP), built to simplify how we go to market and respond to customers with greater speed and precision. You will serve as the primary Specialty Data Science representative on this cross-functional effort, translating deep expertise in Specialty rating programs into clear requirements that inform the platform build. This isn't a program management role, it's about ensuring the science of how we price is preserved, correctly implemented, and positioned to evolve on the new platform.

Condo & RV Programs You will own the pricing design and modeling for the Condo and RV programs, ensuring these products deliver best-in-class segmentation and maintain the highest competitiveness in the marketplace.

Research & Analytical Capacity Beyond Frontier, you will advance the science of Specialty pricing, researching new modeling techniques, evaluating novel data sources, and improving segmentation, while contributing to high-impact research and modeling work across the Specialty portfolio. We don't expect every capability on day one, we expect intellectual curiosity, learning agility, and the drive to add value quickly.

People Leadership You will manage, coach, and develop a team of 3–5 data scientists, building a high-performing culture where people grow, collaborate, and do their best work.
