Responsibilities
- Develop, implement, build, and maintain production knowledge graph solutions across LPG and RDF graph technologies.
- Build scalable pipelines that transform healthcare and FHIR data into graph representations.
- Implement mappings between patient or clinical data and clinical ontology concepts.
- Develop reusable mapping and transformation patterns for graph solutions.
- Implement entity identity, canonical identifiers, URI/IRI, relationships, and concept-linking approaches.
- Maintain provenance and traceability between source data, mapping rules, and resulting graph entities and relationships.
- Develop and optimize graph queries using Cypher and/or SPARQL.
- Implement automated validation and testing for unresolved mappings, inconsistent relationships, and graph-quality issues.
- Collaborate with ontology, FHIR, terminology, and clinical subject-matter experts to clarify mapping requirements.
- Participate in technical design, architecture reviews, code reviews, and engineering best practices.
Requirements
- 5+ years of software or data engineering experience, including hands-on knowledge graph or graph technology experience.
- Strong understanding of knowledge graph and graph data modeling concepts.
- Hands-on experience with Labeled Property Graphs such as Neo4j/Cypher or equivalent, or RDF/semantic technologies such as RDF/RDFS, OWL, and SPARQL.
- Working knowledge of both LPG and RDF graph models.
- Strong programming skills in Python, Java, or similar languages.
- Experience building production data ingestion, transformation, or integration pipelines.
- Experience with graph databases and/or RDF triple stores.
- Understanding of entity identity, graph relationships, mappings, provenance, and data quality.
- Ability to translate conceptual models and mapping specifications into production implementations.
- Ability to work with evolving requirements and cross-functional technical and domain teams.
- Preferred qualifications include hands-on experience with both LPG and RDF/semantic knowledge graphs, healthcare or life sciences data experience, and familiarity with HL7 FHIR.
- Preferred qualifications include experience with ontology-driven data integration, semantic mapping, SHACL or other graph validation approaches, terminology normalization, and canonical concept mapping.
- Familiarity with SNOMED CT, LOINC, RxNorm, ICD, or UMLS is preferred.
- Cloud and CI/CD engineering experience is preferred.
Benefits
- Full-time US-remote employment.
- Up to 25% travel to client sites across the US.
- Opportunities to upskill and work on AI, ML, data, cloud, and other emerging technologies.
- Exposure to Fortune 1000 clients and a research-focused organization with 60+ patents filed.
