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 Masters 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.
What Youll Do
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
