AI Taxonomy Curation Specialist

Adam Li

Freelance · Job · Berlin

About the role

Product catalogs are only searchable if the taxonomy makes sense. But taxonomies evolve — new product categories emerge, old ones become obsolete, and the boundaries between categories shift as markets change. Our AI maintains product taxonomies for 15 e-commerce clients, and we need someone to curate the training data that teaches the AI where products belong. As a freelance taxonomy curator, you'll review AI classification decisions, correct misclassifications, identify categories that need splitting or merging, and build the golden datasets that train the next version of our classifiers. Each client has a unique taxonomy reflecting their product domain. This is knowledge work at the intersection of information science and machine learning. You'll develop expertise in how product categorization systems work — the ambiguities, the edge cases, and the business logic that determines why one classification matters more than another.

Responsibilities

  • Review and correct AI product classification decisions across client taxonomies
  • Identify categories needing splitting, merging, or restructuring
  • Build golden training datasets for taxonomy classifier improvement
  • Document classification edge cases and decision rationale
  • Monitor taxonomy health metrics and flag systematic misclassification patterns

Requirements

  • Python and SQL proficiency for data analysis
  • Strong logical reasoning for category boundary decisions
  • Attention to detail for classification accuracy
  • Interest in information organization and e-commerce
  • Clear documentation skills for classification rationale

Benefits

  • Freelance with ongoing curation engagements
  • Fully remote — European time zones
  • Learn taxonomy design and classification ML
  • Flexible scheduling
