About the RoleThis role sits within the applied science function. You will own the design, development, and production deployment of document understanding systems that directly power Westlaw, PracticalLaw, and CoCounsel. The problems are real, the scale is large, and the expectation is shipped, reliable, measurable impact.You will work across semantic chunking, document enrichment, knowledge graph construction, and synthetic data generation for complex legal, tax, and accounting content. Multiple product teams depend on what this function delivers.About YouYou hold a PhD in Computer Science, AI, NLP, or a related field, with 8+ years of post-degree industry experience taking NLP and document understanding systems from development to production at scale. You have hands-on depth across the full applied arc — model development, distillation, evaluation, and deployment. You publish, you mentor, and you measure success by what ships and performs in production.What You'll DoDesign and deploy semantic chunking models for lengthy, non-uniformly structured legal documents with adjustable granularity across use casesBuild document enrichment systems using legal and customer-defined taxonomiesDevelop LLM-based knowledge graph construction pipelines that extract and link citations, entities, and legal concepts across diverse legal contentLead knowledge distillation efforts to compress large models into latency-constrained, production-ready SLMsDesign evaluation frameworks — component-level and end-to-end — using expert annotation and synthetic dataOwn technical decisions on architecture, chunking strategy, classification approach, and knowledge extraction methodsPartner with engineering on delivery, reliability, and scale across multiple product linesProvide technical input to senior leadership on AI strategy and roadmapMentor applied scientists and ML practitioners on the teamRequired QualificationsPhD in Computer Science, AI, NLP, or a related field — required8+ years of post-degree industry experience shipping document understanding, information extraction, or knowledge graph systems into production — not research-only experiencePublications at ACL, EMNLP, ICLR, NeurIPS, SIGIR, KDD, or equivalentProduction Python and experience with PyTorch, Hugging Face Transformers, and DeepSpeedHands-on production depth required in:Document layout analysis and semantic chunking beyond fixed-size or paragraph-based methodsHierarchical, multi-label document classification with domain-specific and customer-defined schemasEntity recognition and linking, relation extraction, citation parsing, and knowledge graph construction from unstructured textLLM-based information extraction, few-shot and multi-task learning, and post-trainingKnowledge distillation, model compression, and SLM deployment under latency constraintsSynthetic data generation and annotation workflow designEnd-to-end evaluation framework design for document understandingPreferred QualificationsLegal document understanding, legal IE, or legal AI experienceComplex document structures: nested hierarchies, cross-references, non-uniform formattingRetrieval or QA systems over large document collectionsRAG and agentic workflows in enterprise settingsKnowledge graph frameworks for legal or enterprise applicationsAzureML or AWS SageMakerWhat’s in it For You?Flexibility & Work-Life Balance: Flex My Way is a set of supportive workplace policies designed to help manage personal and professional responsibilities, whether caring for family, giving back to the community, or finding time to refresh and reset.
