Senior Applied Scientist, Document Understanding

About the role

This is an applied science position focused on designing, building, and deploying production-grade document understanding systems that power Westlaw, PracticalLaw, and CoCounsel. You will work across semantic chunking, document enrichment, and knowledge graph construction for complex legal, tax, and accounting content - delivering foundational intelligence that multiple product teams depend on at scale. About You You hold a PhD or Master's in Computer Science, AI, NLP, or a related field, with 5+ years of post-degree industry experience shipping document understanding, information extraction, or knowledge graph systems into production. You have hands-on depth across model development, distillation, evaluation, and deployment. You work independently, lead through influence in an applied research setting, and measure success by what ships and performs in production.

Responsibilities

• Design and deploy semantic chunking models for lengthy, non-uniformly structured legal documents with adjustable granularity across use cases
• Build document enrichment systems that classify documents according to legal and customer-defined taxonomies and extract rich metadata
• Develop LLM-based knowledge graph construction pipelines that extract and link citations, entities, and legal concepts across diverse legal content
• Build scalable synthetic data generation systems for model training, multi-hop query simulation, and hallucination-free answer generation
• Apply knowledge distillation techniques to compress large models into latency-constrained, production-ready SLMs
• Design evaluation frameworks - component-level and end-to-end - using expert annotation and synthetic data
• Drive independent technical decisions on chunking strategy, classification approach, knowledge extraction methods, and multi-document reasoning architecture
• Partner with engineering on delivery, reliability, and scale across multiple product lines
• Contribute to published research at venues such as ACL, EMNLP, ICLR, NeurIPS, SIGIR, and KDD, and to intellectual property
• Required Qualifications
• PhD or Master's in Computer Science, AI, NLP, or a related field
• 5+ years of post-degree industry experience shipping document understanding, information extraction, or knowledge graph systems into production - not research-only experience
• Publications at ACL, EMNLP, ICLR, NeurIPS, SIGIR, KDD, or equivalent
• Experience leading through influence in an applied research setting
• Production Python and experience with PyTorch, Hugging Face Transformers, and DeepSpeed
• Hands-on production depth required in:
• Document layout analysis and semantic chunking beyond fixed-size or paragraph-based methods
• Hierarchical, multi-label document classification with domain-specific and customer-defined schemas
• Entity recognition and linking, relation extraction, citation parsing, and knowledge graph construction from unstructured text
• LLM-based information extraction, few-shot and multi-task learning, and post-training
• Knowledge distillation, model compression, and SLM deployment under latency constraints
• Synthetic data generation for NLP: query-answer generation with verification and scalable data augmentation
• Annotation workflow design and evaluation framework development for document understanding tasks

Requirements

• Legal document understanding, legal information extraction, or legal AI applications
• Complex document structures common in legal content: nested hierarchies, cross-references, non-uniform formatting, and embedded elements
• Retrieval, QA, or analysis systems over large document collections
• Knowledge graph frameworks for legal or enterprise applications
• RAG and agentic workflows for enterprise knowledge systems
• AzureML or AWS SageMaker
• #LI-LP2
• New Position: This position is open due to an existing vacancy to support our evolving business needs.
• What's in it For You?
• Industry Competitive Benefits: We offer comprehensive benefit plans to include flexible vacation, two company-wide Mental Health Days off, access to the Headspace app, retirement savings, tuition reimbursement, employee incentive programs, and resources for mental, physical, and finan
