Semantic Platform Engineer

Boston, MA (100% onsite; remote may be considered for strong niche skills)

• Deploy a reused ontology engine and maintain a single semantic repository shared by partner teams.
• Build and run data pipelines that load resolved data into the repository on Azure alongside existing CBM analytics in Databricks.
• Keep deployments portable using containers and infrastructure as code so the solution can move to another cloud without redesign.
• Expose the graph to diagnostic agents through documented, read‑only query endpoints and measure query performance.
• Treat ontology and mappings as code: version, test (competency questions as SPARQL tests and SHACL conformance), and execute in CI.

• 4+ years building knowledge graphs, ontologies, or semantic data platforms used in production.
• Hands‑on experience with RDF/RDFS, OWL 2, SPARQL 1.1, and SHACL.
• Strong Python skills (e.g., rdflib, pySHACL or similar), plus git and CI practices.
• Experience deploying and operating an RDF triple store or reasoner (e.g., GraphDB, Stardog, RDFox, Apache Jena/Fuseki).
• Azure experience with containers, infrastructure as code, and CI/CD, including working with Databricks.

• Work on an AI‑driven service that turns condition‑based maintenance analytics into normalized health scores, contextual diagnostics, and prioritized action plans for critical data center power equipment.
• Build semantic layers that provide diagnostic agents with the asset and relationship context they need (connections, dependencies, and site placement).
• Deliver production‑ready semantic solutions with minimal ramp‑up time in a focused, execution‑driven environment.
• Own end‑to‑end implementation details: pipelines, repository deployment, query endpoints, testing, and documentation.
• Contribute to a code‑driven ontology workflow with CI testing using competency questions and SHACL conformance.
