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.

- 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
Vector databases agent-tool interface development parsing structured file formats exposure to CAE/FEA/CFD, surrogate modeling, or physical AI.
Deep simulation domain knowledge - domain engineers provide that. No PhD or ML research background.
