About the role

Graph Database Developer to join a specialized team building an AI-powered fashion advisory platform. Responsible for the graph data layer from schema design to ingestion, entity resolution, and query performance, enabling real-time style recommendations for end users.

Responsibilities

  • Schema Design: Define node labels and edge types that represent the relationships between designers, garments, style attributes, trends, occasions, and editorial articles.
  • Entity Ingestion: Build workflows that consume structured JSON payloads from the upstream data pipeline and load them into the graph database in batch mode.
  • Probabilistic Entity Matching: Match extracted item mentions to the correct product node in a catalog of 50,000+ SKUs by scoring attribute overlap, assigning a match confidence, and creating the relationship only when it exceeds a defined threshold. Deduplicate items that appear inconsistently across different articles.
  • Editorial Signal Weighting: Assign weights to relationships based on how prominently an item or trend was featured, influencing AI-driven recommendations.
  • Query Optimization: Design and tune openCypher traversal queries, including multi-hop queries, to return relevant results in under three seconds for downstream Amazon Bedrock Agents.
  • Cross-Functional Collaboration: Work with Machine Learning Developer and GenAI Agent Developer to align the graph structure with retrieval and recommendation needs.
  • Technical Validation: Support technical interviews and validation of new team members joining the graph database workstream.
