Description

  • Onboard new entities into the Ads team Knowledge Graph in alignment with defined schemas and ontologies.
  • Serve as the primary point of contact for Product, Engineering, and Analytics teams requesting entity additions or schema changes.
  • Prioritize and triage incoming requests based on business impact, urgency, and technical feasibility.
  • Perform data entry and labeling to support automated content understanding pipelines.
  • Tune and refine LLM prompts to improve content understanding automation.
  • Review and curate LLM-generated entities by approving high-confidence outputs, correcting near-misses, and rejecting hallucinations.
  • Execute QA and validation to ensure ontological consistency and factual accuracy.
  • Create Golden Sets through targeted labeling to assess model quality and support classifier and extraction model fine-tuning.
  • Investigate and resolve data integrity issues, including error correction, duplicate entity merging, and relationship conflict resolution.

Requirements

  • 3+ years of experience with Knowledge Graph.
  • Strong understanding of graph concepts, including nodes, edges, and properties.
  • Experience with taxonomy and ontology, including categorizing data, managing hierarchies, and understanding semantic relationships between entities.
  • Proficiency in navigating complex datasets.
  • Experience with SQL, SPARQL, or Cypher is a strong plus.
  • Understanding of how generative AI works and common failure modes such as hallucinations.
  • Understanding of the importance of ground-truth data in training.
  • This role is intended for a Data Analyst/entry-level profile rather than a Data Scientist or AI/ML engineer.

  • Open to a 12–18 month contract or full-time employment.
