Job Location : Pune

Summary:

Makes our simulation products AI-accessible. Our products have rich programmatic surfaces — scripting APIs, file formats, data structures, workflow logic — that are powerful but not designed for AI consumption. This engineer defines the ontology schema that describes those surfaces, builds the knowledge graphs on top of them, and wraps them as structured, typed interfaces that AI agents can discover and invoke.

Responsibilities:

• Define and maintain ontology schemas describing product capabilities, entities, and relationships
• Build and maintain knowledge graphs over product documentation, APIs, and simulation data
• Build structured tool interfaces exposing product capabilities to AI systems
• Write connectors to product APIs, parsers, and data access layers
• Implement retrieval and context layers over product knowledge
• Work with domain engineers to translate simulation workflows into discrete, callable operations
• Review product ontologies for agentic-readiness across 2–3 products

Skills we need:
