Our AI and Machine Learning teams build systems that help legal professionals reason over case data, understand documents, generate work products, retrieve grounded answers, and automate high-value legal workflows. This work requires strong technical execution, but also deep legal judgment. We need people who can help define what high-quality legal AI output looks like and ensure our systems work in the context of real legal practice.
