Full Job Description
Basic Qualifications
Bachelor's degree in Systems Engineering, or a related Science, Engineering or Mathematics field, plus a minimum of 8 years of relevant experience; or Master's degree, plus a minimum of 6 years of relevant experience. Responsibilities for this Position
What You'll Own
  • Domain ontologies. Design and maintain semantic schemas that describe key engineering and manufacturing entities — products, BOMs, plants, equipment, processes, work orders — and their relationships across systems.
  • Knowledge graphs. Implement ontologies using semantic web or graph technologies (RDF/OWL/SHACL/SPARQL or property-graph equivalents like Neo4j). Build, query, validate, and tune knowledge graphs in production.
  • Data alignment. Integrate heterogeneous data sources — PLM, ERP, MES, CMMS, QMS, data lakes — into a common vocabulary. Align schemas, code sets, and master data to the ontology so AI services see one coherent picture.
  • Semantic layer. Design the enterprise semantic layer that BI tools, analytics platforms, and AI/LLM applications query consistently. Define core business entities, metrics, and hierarchies and map them to existing data stores.
  • Ontology governance. Manage versioning, documentation, reuse of industry standards, and enforcement of modeling best practices across pods. Your ontologies are shared assets — they must be maintainable by others.
What You Won't Own
  • AI model development or prompt engineering — you provide the data substrate, the AI engineers build on it
  • Enterprise system administration — you integrate data from systems, you don't manage them
  • Business process decisions — Domain SMEs and the Product Owner define what matters; you model it
What Makes This Role Different
  • Your ontologies directly feed AI systems that make real business decisions. A bad data model doesn't just slow a report — it makes an AI agent reason incorrectly.
  • You will work across multiple enterprise domains — HR, manufacturing, CRM, supply chain — building a shared knowledge architecture, not siloed data models.
  • You will collaborate with business SMEs who understand the domain and AI engineers who consume your models. You translate between both worlds.
Required Qualifications
  • Bachelor’s degree in Computer Science, Data Science, Information Science, or a related field, plus 5 years of experience; or Master’s degree plus 3 years of experience
  • Hands-on experience with knowledge graph or ontology technologies — RDF/OWL/SHACL/SKOS, SPARQL, and/or graph databases (Neo4j, Stardog, Ontotext, AWS Neptune, or similar)
  • Experience integrating disparate enterprise data sources into a shared vocabulary or knowledge graph — you have aligned data across systems that use different schemas, code sets, and terminology
  • Strong data modeling skills — dimensional modeling, semantic modeling, or formal ontology design applied in production, not just academic settings
  • Experience with enterprise data platforms — data warehouses, data lakes, Snowflake, Palantir Foundry, or similar
  • S. citizenship required. Department of Defense Secret security clearance is required at time of hire.
Preferred Qualifications
  • Experience building semantic layers or metrics layers consumed by BI, analytics, or AI/LLM applications
  • Experience with enterprise systems data (ERP, MES, PLM, CRM) — you understand the data structures these systems produce
  • Familiarity with AI/ML data requirements — embeddings, vectorization, retrieval-augmented generation, and how knowledge graphs support LLM reasoning
  • Comfortable leading workshops with non-technical business SMEs to capture requirements and iteratively refine data models
  • Experience with ontology governance — versioning, documentation, standards reuse across teams or an enterprise
What Sets You Apart
  • You think in relationships, not rows. You see connections between data that others model as flat tables.
  • You can explain a semantic model to a business SME and have them recognize their domain in it.
  • You build ontologies that other people can use and extend — not elegant models that only you understand.
  • You have integrated data from systems that were never designed to work together and made it coherent.
  • You care about data meaning, not just data structure. You know that two systems calling something "part number" doesn't mean they mean the same thing.
Details
  • Remote — 100% telework
  • 9/80 schedule
  • Defense industry experience is not required
