Responsibilities
Semantic Model Design: Contribute to the design, development, and iterative refinement of complex semantic data models, with a focus on ontologies, knowledge graphs, and property graphs
Requirement Translation: Assist senior team members in translating intricate, cross-functional business needs into formal, scalable knowledge graph structures, ensuring tight alignment with the enterprise data strategy
Governance and Standards: Document semantic assets, including detailed entity definitions, relationship types, axioms, constraints, and data lineage, ensuring adherence to established best practices and fostering consistency across the organization
Graph Data Analysis & Feature Engineering: Utilize data science methodologies and Python scripting to conduct exploratory data analysis (EDA) on graph structure, identify data patterns, perform feature engineering, and support advanced analytics based on the knowledge graph
Data-Driven NLP Integration: Apply Natural Language Processing (NLP) techniques and tooling to unstructured clinical text and data streams to identify, extract, and map new entities, attributes, and relationships directly into the semantic models, effectively structuring raw data for machine learning consumption
Robust Data Quality: Implement and maintain data quality frameworks, validation rules (e.g., using SHACL), and transformation logic within the semantic layer to ensure the accuracy, reliability, and consistency of the knowledge graph
Cross-Functional Partnership: Partner closely with Staff semantic engineers, clinicians, content teams, and business leaders to understand domain knowledge and requirements, and ensure semantic solutions effectively meet organizational objectives
Research & Evaluation: Assist in researching, evaluating, and utilizing new technologies, methodologies, and best practices in semantic modeling, knowledge graph technologies, and NLP to drive continuous process improvement
Knowledge Sharing: Proactively share technical expertise and knowledge with peers and cross-functional teams
Qualification
Required
BA/BS in a STEM field (e.g., Computer Science, Data Science, Bioinformatics) with 3-5 years of hands-on work experience in data modeling or data engineering
Proven hands-on experience in semantic modeling concepts (ontologies, knowledge graphs, property graphs)
Expertise in Python for data manipulation, analysis, and pipeline development, including libraries like Pandas/NumPy
Strong understanding of statistical and machine learning concepts (e.g., classification, clustering, regression) and their application to graph-based data
Demonstrated experience with NLP technologies and libraries (e.g., NLTK, spaCy, Gensim, Hugging Face) for text extraction, named entity recognition, or relationship extraction
Strong working knowledge of graph database platforms (e.g., Amazon Neptune, Neo4j, etc.) and graph query languages (e.g., SPARQL or Gremlin)
Familiarity with semantic web standards like OWL, RDFS, and SHACL
Experience with relational databases (SQL) and general data warehousing concepts
Ability to communicate complex technical concepts effectively to both technical and non-technical stakeholders
Experience in an Agile/Scrum environment, iteratively developing and deploying data solutions
Preferred
Practical experience with AWS data services (e.g., Glue, Sagemaker) and ETL/ELT methodologies
Understanding healthcare ontologies and standards like SNOMED-CT, LOINC, RxNorm, and ICD-10
