Lead Semantic Data Engineer

Our company is seeking a lead semantic data engineer to architect, build, and scale enterprise-grade knowledge graph solutions that power advanced analytics and decision-making in pharmaceutical research. This role will lead the design of semantic data layers that integrate heterogeneous scientific datasets, enabling end-to-end traceability, cross-domain insights, and AI/ML-driven discovery. The ideal candidate will combine deep expertise in knowledge graphs, ontology engineering, and data engineering, with strong domain awareness in pharmaceutical R&D.

Key responsibilities

• Design and implement scalable knowledge graph architectures to integrate multi-modal data (e.g., omics, process, analytical, lineage)

• Build and manage graph data models representing entities such as samples, processes, assays, targets, and biological relationships

• Drive adoption of graph technologies (e.g., RDF, property graphs, SPARQL/Cypher)

• Partner with platform teams to implement scalable infrastructure (e.g., Amazon Neptune, serverless pipelines)

• Ensure performance, scalability, and governance of knowledge graph platforms

• Collaborate with product managers, scientists, data engineers, and AI/ML teams to translate business needs into semantic models

• Define and execute the knowledge graph roadmap aligned with enterprise data product strategy

• Mentor engineers and establish best practices in ontology development, modeling, and graph engineering

• Drive adoption of knowledge graph capabilities across use cases and programs
  

Required experience and skills

• Semantic web technology stack (e.g., RDF data format, SPARQL query language)

• Amazon Web Services, particularly the serverless services (e.g., Lambda, Step Functions)
