Role Purpose
Build the Entity Graph. This role converts the resolved, canonical entity data into a production graph — implementing node and edge projections, loading and optimising the graph, enabling multi-hop traversal, and validating that the graph faithfully represents entity, ownership and affiliation relationships back to source.
Key Responsibilities
- Graph schema implementation — implement the graph schema defined by the architect: node types, edge types, properties, keys and constraints.
- Relational-to-graph projection — build and operate the projection logic that converts canonical relational entity tables into graph nodes and edges, with full source attribution.
- Graph loading & pipelines — develop and optimise graph load processes;
implement incremental re-projection triggered by change data capture.
- Relationship modelling — implement entity-to-entity, ownership (parent/subsidiary), officer/director and affiliation relationships, including bitemporal handling where required.
- Traversal & query engineering — write and optimise graph queries (GQL/Cypher-style)
supporting multi-hop traversal scenarios such as corporate family trees and shared-agent affiliations.
- Performance optimisation — tune graph queries and load performance;
profile traversal cost;
address scale bottlenecks.
- Graph quality validation — implement automated checks on node/edge counts, orphan detection, relationship integrity and source traceability.
- Consumption support — support exposure of graph data through API and SQL endpoints, and collaborate on GraphRAG indexing over graph projections.
