Do you enjoy being part of a global team that works with a diverse range of products and technology?

Do you enjoy mentoring other engineers, and helping them grow their careers?

About our Team:

Knowledge Innovation & Taxonomy Engineering (KITE) is the team within Elsevier Operations responsible for the taxonomies, vocabularies and knowledge graphs that sit beneath many of Elsevier's products. In plain terms, a taxonomy is a structured, standardized, vocabulary of concepts, - such as diseases, drugs, materials or research topics - and the relationships between them. This shared structure is what lets our products tag content consistently, return relevant search results, connect related information, and feed reliable, well-grounded answers to AI features.

Main areas of work

• Taxonomy automation development - pipelines, scripts and tools that speed up taxonomy creation and editorial work.
• Platform development and support for CENtree, the shared taxonomy-management system used across all teams.
• Automated Curation and enrichment of taxonomies with semantic structure and relationships and their operationalization as reusable services.

About the Role:

We are looking for an individual to support our team in linking our existing taxonomies and ontologies in a meaningful way, applying linked data standards and best practices. The ideal candidate combines strong technical skills in semantic web technologies with a solid understanding of data modelling for knowledge organization systems.

Responsibilities:

• Design and implement methods for linking and aligning existing taxonomies and ontologies
• Model and maintain controlled vocabularies, taxonomies and ontologies using SKOS, SKOS-XL, and OWL
• Query and manipulate semantic data using SPARQL
• Integrate taxonomy/ontology data with other systems via REST APIs
• Write and maintain Python scripts/tools to support data modeling and integration workflows
• Collaborate with the team to understand data needs and translate them into semantic data models

Requirements:

• Extensive hands-on experience with SPARQL
• Advanced Python programming skills
• Experience working with REST APIs
• Good data modelling experience
• Experience with at least one taxonomy/ontology management tool (e.g., Centre, Synaptica, Top Braid, Protégé, or equivalent)
• Understanding of linked data standards and principles
• Familiarity with semantic web standards (RDF, RDFS, JSON-LD)
• Ability to understand and translate business/data needs into semantic modeling solutions

Nice to Have

• Prior experience linking or aligning multiple taxonomies/ontologies at scale
• Experience using Git/GitHub
• Understanding of AWS (specifically Batch, Lambda, Athena, S3, ECR, RDS, SNS/SQS)
• Hands-on knowledge of automation, CI/CD a plus
• Background in Life Sciences or similar
• Experience with SHACL
