Senior Data Scientist

AI for Science, Research Intelligence & Knowledge Discovery

Do you want to build advanced AI that helps researchers discover, understand, and advance science?

At Elsevier, data science isn’t about building models for their own sake. It’s about doing science for science: creating intelligent systems that help the global research and healthcare communities make better decisions, uncover trusted insights, and accelerate scientific progress.

We are growing our Data Science organization within Technology, and we are looking for Senior Data Scientists who want to work at the frontier of applied AI — machine learning, natural language processing, large language models, retrieval, reasoning workflows, knowledge discovery, and state-of-the-art generative AI built specifically for science.

You will help solve some of the hardest AI problems in the world: building systems that understand scientific language, reason across trusted content, connect ideas across disciplines, and support researchers as they explore the frontiers of knowledge.

You will work with vast, complex, and heterogeneous data — from scientific publications and raw research datasets to biomedical content, citations, metadata, ontologies, taxonomies, knowledge graphs, multilingual content, and domain-specific data across the full spectrum of scientific disciplines.

This is AI with purpose: helping researchers advance science, improve health outcomes, and contribute to human progress.
