Director, Data Science

Description

Are you looking for a hands-on role at the cutting edge of Generative AI research and solutioning in insurance? Do you want to design and implement science-driven GenAI features spanning multimodal data such as imagery, structured data, text, and audio that can transform pricing, risk evaluation, and product innovation?

The Modeling Sophistication Deep Learning Research team is seeking a highly skilled technical leader who combines strong research depth with practical engineering ability. In this role, you will be both building end-to-end GenAI solutions yourself and providing technical direction, mentorship, and influence to peers and partners. You will explore novel architectures, LLM-based pipelines, retrieval-augmented generation (RAG) applications and evaluation, multimodal fusion, and generative approaches for creating new features, while ensuring seamless integration into Liberty Mutual's business applications.

This position is ideal for someone with deep curiosity, tenacity, and the drive to scale the impact of GenAI research across diverse insurance products without traditional managerial responsibilities.

This role may have in-office requirements based on candidate location.
