At Cadence, we hire and develop leaders and innovators who want to make an impact on the world of technology.

AI Full Stack Engineer, Ontologies & Knowledge Graphs (Agentic AI, Surrogates, Physical AI) -

Exp: 6+yrs

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

• Strong Python; experience building and consuming REST APIs
• Familiarity with graph databases and/or ontology/semantic modeling (RDF, OWL, property graphs, or equivalent)
• Experience with at least one agent framework (LangChain, LangGraph, AutoGen, CrewAI, or similar)
• Understanding of how LLMs consume context and call tools
• Comfortable working within unfamiliar or undocumented codebases
• Systems thinker - able to decompose a complex legacy workflow into discrete, callable steps
