Principal Software Architect, Building Ontology

Key Responsibilities Ontology & Semantic Model Development Design, build, and maintain industrial ontologies, taxonomies, and knowledge models covering assets, spaces, processes, and operational data. Develop and extend models aligned with industry standards such as: Brick Schema Project Haystack ASHRAE 233P IFC (Industry Foundation Classes) Related building, utilities, energy, or asset-management ontologies

Define clear concept hierarchies, relationships, constraints, and naming conventions . Conduct ontology alignment and integration with external knowledge bases and domain-specific ontologies. Standards & Interoperability Map, align, and reconcile concepts across multiple industry schemas and customer-specific models. Design semantic alignment strategies between heterogeneous data sources (BMS, IoT, SCADA, CMMS, ERP, digital twins). Ensure models support interoperability, extensibility, and backward compatibility . Leverage large language models (e.g., GPT-4, Claude, LLaMA, Mistral) and NLP pipelines to automate ontology population, entity extraction, and relation classification Applied Semantics & Engineering Collaboration Work closely with data engineering and platform teams to: Operationalize ontologies in production systems Support semantic querying, reasoning, and metadata-driven pipelines

Define best practices for ontology versioning, governance, and lifecycle management . Translate abstract semantic models into practical, implementable artifacts . Architecture Leadership & Strategy Define the long-term technical vision and roadmap for the enterprise semantic and knowledge graph platform. Establish architectural standards, design patterns, and reference architectures for semantic data integration across business units. Partner with data engineering, ML, product, and business teams to translate domain requirements into graph and semantic models. Evaluate and recommend emerging technologies, tools, and open standards in the knowledge graph and AI/LLM landscape. Represent the organization in external technical communities, standards bodies, and industry working groups.
