  • Apply semantic chunking, embeddings, versioning, and indexing techniques
  • Implement metadata standards, taxonomy, and content classification
  • Translate governance and compliance requirements into enforceable system rules
  • Enable privacy‑safe retrieval (RBAC, PII handling, audit logging)
  • Evaluate retrieval quality using metrics such as precision, recall, and answer faithfulness
  • Instrument logging and observability to improve content health and retrieval accuracy
  • Support pilots, launches, and scaling of AI‑enabled HR content experiences

Requirements

  • Hands‑on experience delivering AI‑ready content or retrieval systems in an enterprise environment
  • Strong knowledge of: Information architecture and content structuring
  • Metadata, taxonomy, and content classification
  • Retrieval‑augmented generation (RAG) or enterprise search
  • Experience with semantic chunking, embeddings, and indexing
  • Familiarity with privacy‑safe AI patterns and governance controls
  • Ability to operate as a lead contributor in cross‑functional teams
