Job Description

BWX Technologies is seeking a Principal Data Engineer to lead semantic modeling and industrial knowledge architecture efforts for real-time operational intelligence in advanced manufacturing settings. This on-site role in Oak Ridge, Tennessee supports enterprise knowledge graphs and ontology-driven systems within a high-security DOE/NNSA environment.

Role Summary

In this position, you will design, engineer, and govern large-scale semantic data models and industrial knowledge systems. The work includes supporting enterprise knowledge graphs, ontology-driven architectures, and interoperable data foundations to enable integration across advanced manufacturing domains.

Responsibilities

Design semantic data models and ontologies for unified interpretation of industrial data across chemical, aerospace, automotive, and high-throughput manufacturing sectors.
Develop enterprise knowledge graph components using OWL, RDF, RDFS, SKOS, SHACL, and SPARQL.
Build unified namespaces aligned with ISA-95 and W3C standards to support cross-system interoperability.
Architect scalable storage solutions including time-series databases, knowledge graphs, and lakehouse systems.
Engineer pipelines to ingest, reconcile, and contextualize structured, semi-structured, streaming, and unstructured data.
Apply governance practices including versioning, modularization, URI strategies, and quality gates.
Map relational models into semantic representations using R2RML and RML.
Support AI/ML and simulation teams by embedding semantic models into analytics and automation workflows.
Lead workshops with SMEs to define domain concepts, modeling requirements, and competency questions.
Implement data quality controls, lineage, validation frameworks, and anomaly detection.
Develop reusable frameworks for units modeling, hierarchical structures, identifier normalization, and event modeling.
Mentor engineering teams and contribute to enterprise data modernization strategies.
