Semantic Platform Engineer

Our client is seeking a Semantic Platform Engineer to join their team. As a Semantic Platform Engineer, you will be part of the Engineering organization supporting the Semantic Platform and Data Integration effort. The ideal candidate will have hands-on RDF/OWL development, strong semantic layer implementation, and the ability to translate business requirements into production-ready solutions which will align successfully in the organization.

Job Title: Semantic Platform Engineer

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

What's the Job?

• 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.

What's Needed?

• 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.

What's in it for me?

• 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.

Upon completion of waiting period consultants are eligible for:

• Medical and Prescription Drug Plans
• Dental Plan
• Vision Plan
• Health Savings Account
• Health Flexible Spending Account
• Dependent Care Flexible Spending Account
• Supplemental Life Insurance
• Short Term and Long Term Disability Insurance
