Taxonomy specialist

What does the role Taxonomy specialist do?

The Taxonomy Specialist designs, builds, and governs the controlled vocabularies, classification schemes, and metadata frameworks that underpin how content is organised, labelled, and found across the intranet and digital workplace. Where the Information Architect defines the structural logic of navigation and site organisation, the Taxonomy Specialist focuses specifically on the semantic layer: the terms, hierarchies, relationships, and metadata that make content retrievable through search, filters, and AI-assisted tools. The role requires a blend of linguistic precision, user research, and governance discipline, and is increasingly important as organisations depend on metadata quality for enterprise search performance and AI knowledge retrieval.

Outline job description

The Taxonomy Specialist designs, builds, and governs the controlled vocabularies, classification schemes, and metadata frameworks that make content retrievable: through search, filters, and increasingly through AI tools. Where the Information Architect defines the structural logic of navigation and site organisation, the Taxonomy Specialist focuses on the semantic layer: the terms, hierarchies, relationships, and metadata that determine whether content can actually be found.

About the role

It's a role that requires linguistic precision, user research skills, and governance discipline in roughly equal measure. You'll be designing systems that need to be rigorous enough to work at scale, but intuitive enough that content authors can apply them without a specialist on hand. As AI retrieval depends heavily on metadata quality to surface accurate answers, the work of this role has moved firmly into the mainstream of digital workplace governance.

The Taxonomy Specialist most commonly sits within the Knowledge Management Team, working closely with the Information Architect on the structural side and with the Search Manager on how taxonomy affects search relevance and AI retrieval performance.

What you'll actually be doing

You'll be maintaining and evolving a live enterprise taxonomy: adding new terms, managing relationships and hierarchies, resolving inconsistencies, and conducting regular audits to keep the classification system coherent as the organisation's content and language evolve. You'll also be defining and governing the metadata schemas that support search and retrieval, and working with content owners and publishing tools to make sure the taxonomy is actually being applied at the point of authorship rather than retrofitted later.

Search analytics and zero-results data will be part of your regular toolkit; they are how you spot where the taxonomy is failing and what needs to change.

What we're looking for

Deep expertise in taxonomy design and controlled vocabulary development: hands-on experience building and governing taxonomies in real organisational environments. An understanding of metadata standards and schemas, and how taxonomy interacts with enterprise search relevance and AI retrieval. Familiarity with thesaurus standards such as SKOS and ISO 25964 is advantageous.

The ability to work practically with content owners who aren't taxonomy specialists, explaining why it matters and supporting them to apply it correctly, is as important as the technical knowledge.

Typical background

Most people in this role come from information science, library science, or knowledge management backgrounds. A postgraduate qualification in information science or a related discipline is common. Enterprise content management, search platform, or knowledge management tool experience is normally expected.

While this role typically focuses on internal systems, a taxonomy specialist may also get involved with external-facing channels such as product catalogues, sales environments and corporate websites. The taxonomy specialist sounds like a very technical role, but it also involves working with stakeholders around the business.

Errors? Disagreements? Omissions?

We have hopefully created these exemplars with thought and care. It is not the only way of looking at these roles and teams in the world, and relates specifically to the intranet and digital workplance profession. It therefore concentrates on some things and ignores others.

If you find an error, disagree wholeheartly or feel there is a glaring ommission we'd love to know.
