Want to apply AI to real scientific and healthcare challenges?

At Johnson & Johnson Innovative Medicine, we are building AI-powered applications that help teams find evidence faster, analyze scientific information at scale, and reduce manual work in research and evidence-generation workflows.

We are looking for a Senior Data Scientist based in Madrid or Milan to design, build, test, and deploy AI solutions that combine machine learning, large language models, data engineering, and software development. You will work closely with scientists, medical experts, product managers, engineers, and business stakeholders to understand their workflows, challenges, and unmet needs. Rather than simply implementing predefined requirements, you will help shape solutions by translating complex scientific and business problems into practical technology capabilities,



including AI-powered approaches where appropriate.

This is a hands-on technical role for someone who enjoys solving complex challenges, writing high-quality code, testing AI outputs, and building scalable solutions that deliver meaningful value in scientific and healthcare workflows.

What You Will Do

You will build applications that support scientific literature search, evidence synthesis, data exploration, study planning, and scientific content generation. This includes working with Large Language Models, Retrieval-Augmented Generation, prompt design, APIs, databases, cloud services, and enterprise data sources.

You will write and review Python code, develop data pipelines, integrate AI models, troubleshoot technical issues, and help move prototypes into production. You will also improve existing workflows by making them more accurate, scalable, maintainable, and easier to test.

A key part of the role is AI qualit
