Ready to lead a data science organization that pushes the boundaries of what intelligent systems can achieve?
Do you thrive on shaping strategy, inspiring teams, and delivering solutions that create real-world impact?
About The Team
Elsevier’s mission is to help researchers, clinicians, and life sciences professionals advance discovery and improve health outcomes through trusted content, data, and analytics. Our Search & Evaluation organization plays a critical role in shaping the future of AI-powered discovery by building intelligent retrieval, ranking, and evaluation systems that power trusted scientific and healthcare experiences.
The team is responsible for advancing search relevance, retrieval quality, experimentation frameworks, and AI evaluation capabilities across Elsevier’s next-generation AI platforms and products.
We combine expertise in information retrieval, machine learning, analytics, experimentation, and generative AI to improve how users discover, synthesize, and interact with scientific knowledge.
Our work spans semantic search, retrieval-augmented generation (RAG), ranking systems, LLM evaluation, online experimentation, and scalable evaluation infrastructure. We partner closely with Product, Engineering, UX Research, Knowledge Graph, and Applied AI teams to deliver measurable improvements in AI quality and user outcomes.
About The Role
We are looking for a Director, Data Science – Search & Evaluation, to lead the strategic direction, technical vision, and organizational development of our Search & Evaluation function.
This role will focus on defining and scaling evaluation frameworks, search relevance methodologies, retrieval optimization strategies, and AI quality measurement systems across Elsevier’s AI-powered discovery experiences.
You will lead a multidisciplinary team of Senior Data Scientists and Data Analysts responsible for evaluating and improving search, ranking, retrieval, recommendation, and generative AI systems. You will help establish best practices for experimentation, evaluation rigor, and AI quality while influencing product strategy and technical direction across multiple initiatives.
This role is ideal for a leader with deep expertise in search relevance, information retrieval, experimentation, and AI evaluation who can combine technical depth, strategic thinking, organizational leadership, and strong cross-functional influence.
