LexisNexis Intellectual Property Solutions is seeking a highly skilled NLP Expert with proven expertise in semantic embeddings and knowledge graphs. This is a research-driven, hands-on role where you will design, build, and optimize language technologies that transform how customers search, analyze, and interact with intellectual property (IP) data.

You will join a collaborative team of data scientists, AI engineers, and domain experts to push the boundaries of how semantic representations and graph-based reasoning can enhance search, discovery, and predictive insights in the IP domain.

At LexisNexis, we value curiosity, innovation, and collaboration. You will be part of a vibrant community of data scientists and AI engineers, with dedicated time for continuous learning while also mentoring junior colleagues.

• Apply state-of-the-art techniques in embeddings, transformers, and generative language models to IP data.
• Design and enhance knowledge graph architectures to capture domain knowledge and enable advanced reasoning.
• Integrate embeddings and NLP methods with graph-based systems to power knowledge-driven insights.
• Prototype and validate new approaches, transitioning successful methods into production-grade systems in collaboration with AI engineering teams.
• Mentor and support junior data scientists, fostering a collaborative and innovative culture.
• Stay current with state-of-the-art NLP and graph research, applying and adapting new methods to real-world problems in intellectual property.
• Contribute to the internal knowledge base by publishing technical reports, presenting at internal forums, and, where appropriate, authoring external publications or patents.
• Work with product managers and business stakeholders to deliver customer-focused solutions with measurable impact.

• Master’s or PhD in Computer Science, Computational Linguistics, Artificial Intelligence, or related discipline.
• 5+ years of hands-on experience building NLP solutions in a research or commercial environment.
• Proven expertise in modern NLP techniques (e.g., semantic embeddings, transformer architectures, generative models) with experience evaluating, optimizing, and scaling NLP models.
• Strong experience with knowledge graph design, construction, and integration with NLP systems.
• Hands-on skills in Python and modern ML frameworks (e.g., PyTorch, TensorFlow).
• Excellent problem-solving and communication skills, with experience collaborating in cross-functional, agile teams.

• Familiarity with graph databases (Neo4j, RDF, SPARQL) and distributed knowledge graph systems.
• Publications, patents, or conference presentations in relevant NLP or ML venues.
