Data Scientist III

As a Data Scientist at Elsevier, you will design, build, evaluate, and productionize the AI and machine learning solutions that power the scientific and knowledge-discovery applications used by research and healthcare communities around the world.

You will work with some of the richest and most challenging data anywhere — enormous, heterogeneous, and intellectually deep: scientific literature, raw research datasets, structured and unstructured content, metadata, citations, ontologies, knowledge graphs, domain taxonomies, and large-scale behavioral and usage signals.

You will pair strong data science fundamentals with the most capable modern AI: classical machine learning, deep learning, large language models, retrieval-augmented generation, semantic search, ranking, entity extraction, classification, recommendation, and evidence-grounded generative AI.

You will own meaningful problems from day one — whether that means shaping a critical model component, designing an end-to-end AI capability, or driving the technical direction of complex data science solutions across teams.

We value practical problem-solving, scientific curiosity, engineering discipline, and the thoughtful use of technology.

We don’t chase trends for their own sake.

We choose the right method for the problem, measure impact rigorously, and build systems that are reliable, scalable, explainable, and genuinely useful in the real world.

You will work on high-impact AI and data science that helps people explore, understand, connect, and act on complex scientific information.

In this role you will:

• Design and build machine learning, NLP, and generative AI systems for scientific discovery, knowledge extraction, decision support, and intelligent content understanding.
• Work with large-scale, complex, and heterogeneous data — scientific publications, research datasets, knowledge graphs, ontologies, taxonomies, citations, metadata, and content from every scientific discipline.
• Apply the right technique to each problem, from classical ML methods such as classification, regression, clustering, ranking, and feature engineering to modern approaches using deep learning, embeddings, LLMs, retrieval, and generative AI.
• Develop capabilities for semantic search, information retrieval, entity extraction, content classification, recommendation, ranking, summarization, question answering, and evidence-grounded generation.
• Build, evaluate, and continuously improve models that help researchers discover relevant knowledge faster, make better decisions, and advance science.
• Train, fine-tune, prompt, evaluate, and integrate models into robust production systems.
• Design evaluation frameworks that measure quality, relevance, reliability, model performance, user value, and real-world impact.
• Write clean, tested, production-quality Python and contribute to reusable data science components and packages.
• Build and maintain scalable data pipelines for preprocessing, model inference, experimentation, monitoring, and continuous improvement.
• Collaborate closely with engineering, product, UX, analytics, research, and domain experts to turn ambiguous scientific and business challenges into robust technical solutions.
• Support deployment, monitoring, model maintenance, drift detection, automated retraining, and ongoing optimization of data science systems.
• Communicate technical concepts, model behavior, insights, trade-offs, and recommendations clearly to both technical and non-technical audiences.

At Elsevier, you won’t be solving generic AI problems.

You will be building AI for the global knowledge ecosystem — the systems that help science itself move forward.

You will help build AI that understands scientific language, connects ideas across disciplines, surfaces trustworthy evidence, reveals hidden relationships between concepts, and supports researchers as they push the boundaries of human understanding.

The data is vast.

The problems are among the hardest in science.

The mission could not matter more.

You may work with:

• Scientific publications and full-text content.
• Research metadata, citations, abstracts, author networks, and institutional data.
• Scientific raw-data repositories and structured research datasets.
• Knowledge graphs, ontologies, taxonomies, vocabularies, and entity networks.
• Multidisciplinary content across life sciences, physical sciences, engineering, medicine, social sciences, and beyond.
• User behavior and interaction signals that sharpen discovery, relevance, personalization, and decision support.
• Generative AI systems that must be accurate, scalable, explainable, source-grounded, and trusted.

Your work will help researchers save time, discover connections, generate new insights, and accelerate the pace of science.

We are interested in people who bring a mix of curiosity, technical depth, collaboration, and a drive for real impact — and we will shape the role around the strengths you bring.

You might be early in your career, with strong foundations in machine learning, analytics, Python, experimentation, and applied problem-solving, and eager to grow your expertise in modern AI, NLP, and scientific data.

You might already design, build, evaluate, and deliver data science components and models independently across the full lifecycle.

Or you might lead the design of complex AI and machine learning solutions — shaping technical approaches, weighing trade-offs, mentoring others, and influencing stakeholders.

Wherever you sit on that spectrum, we want to hear from you.

• A background in data science, machine learning, artificial intelligence, NLP, statistics, applied mathematics, computer science, or a related quantitative field.
• Strong Python skills and a habit of writing clean, maintainable, well-tested code.
• A solid grasp of machine learning fundamentals, including supervised and unsupervised learning, feature engineering, model evaluation, model selection, and performance measurement.
• Experience working with structured, semi-structured, or unstructured data, especially large-scale text or content datasets.
• Familiarity with common data science and ML tools such as Pandas, NumPy, SciPy, Scikit-learn, PyTorch, TensorFlow, or Matplotlib.
• The ability to translate complex and ambiguous requirements into practical, measurable, data-driven solutions.
• Strong analytical thinking, problem-solving skills, and attention to quality.
• Clear communication, with the ability to explain technical concepts, insights, and trade-offs to different audiences.
• A collaborative approach to working with engineering, product, and business stakeholders.
• A genuine interest in building production-ready systems that deliver real user value.

Relevant experience might include any of the following — we don’t expect all of it:

• Large language models and applied LLM workflows.
• Retrieval-augmented generation, semantic search, embeddings, ranking, and information retrieval.
• NLP techniques such as classification, entity extraction, clustering, summarization, topic modeling, question answering, and text generation.
• Deep learning and neural network approaches for language, content understanding, or prediction.
• Evaluation of LLM outputs, AI-generated content, source-grounded answers, and evidence-based systems.
• Agentic or orchestrated AI workflows, including multi-step reasoning, tool use, and frameworks such as LangChain, LangGraph, or similar.
• Knowledge systems, knowledge graphs, ontologies, taxonomies, or citation-aware AI.
• Knowing when to reach for classical machine learning, deep learning, LLM-based approaches, rules, retrieval, or hybrid systems.
• Model monitoring, drift detection, retraining strategies, performance reporting, and continuous improvement.
