Applied AI engineer, knowledge graph
Posted 3 days 19 hours ago by Adverant, Inc.
Build the heart of Nexus: the knowledge graph, the ontology builder and the GraphRAG retrieval that gives every AI answer the context of a whole business.
Our customers want answers they can trust, drawn from everything their company knows. That depends on extraction that gets facts right, an ontology people can shape on screen, and retrieval that follows the connections between things rather than matching words.
You will work across the stack, from how a scanned contract becomes facts in the graph to how those facts reach a model with their sources attached.
What you'll do- Improve extraction, entity resolution and the way facts keep their sources.
- Build and tune GraphRAG retrieval, including community summaries for broad questions.
- Make the ontology builder easier for domain experts to use.
- Measure quality with real test sets, and publish what you find internally.
- Work with industry leads to model new domains.
- Production experience with retrieval, search or knowledge graphs.
- Strong Python, and comfort with a typed language.
- Experience evaluating language models on real tasks.
- A habit of checking results against what people actually need.
- Clear writing about trade-offs.
- Graph databases, ontologies or semantic modelling.
- Information extraction from messy documents and scans.
- Work in insurance, law, finance or another document-heavy field.
