The Hartford is hiring a Sr Knowledge Engineer

About the Role

This role is focused on advancing enterprise AI capabilities by reengineering outdated text processing systems into robust, Python-driven natural language processing (NLP) solutions. You will lead the full lifecycle transition from rule-based platforms to scalable, maintainable architectures that support long-term innovation.

Key Responsibilities

  • Lead the complete migration of legacy text processing systems to modern, Python-based NLP frameworks, enhancing scalability and adaptability.
  • Refactor existing linguistic rules and grammar logic into efficient, production-grade NLP pipelines using standard libraries and best practices.
  • Design and maintain high-precision, context-sensitive extraction models to identify entities, attributes, events, and relationships critical to product development and analytics.
  • Develop and apply domain-specific ontologies and taxonomies to ensure consistent interpretation of language and improve the explainability of results.
  • Translate evolving business needs into accurate, testable extraction logic, ensuring alignment with canonical data models and controlled vocabularies.
  • Collaborate across technical and non-technical teams to communicate NLP capabilities, constraints, and optimization strategies clearly.

Qualifications

  • Bachelor’s or Master’s degree in Computer Science, Data Science, Engineering, or related field, or equivalent professional experience.
  • Minimum of 7 years in data transformation and development with a focus on NLP, particularly within insurance or similar domains.
  • At least 5 years of hands-on experience with Python and SQL in production environments.
  • Proven track record building rule-based and hybrid (rules + machine learning) text extraction systems.
  • Direct experience creating and applying ontologies to structure unstructured text and improve semantic accuracy.
  • Deep understanding of linguistic feature engineering, dependency parsing, negation detection, and section-aware processing.
  • Experience debugging and optimizing complex text pipelines and evaluating performance through precision, recall, and error analysis.
  • Familiarity with data integration patterns and how extracted features feed into analytics, ML models, and enterprise applications.
  • Ability to adapt quickly in environments where domain models and terminology evolve alongside product development.
