Johnson & Johnson Innovative Medicine (J&J IM) is recruiting for a Senior Scientist – Generative AI for Workflow, Applications and Plug-ins development Team. This position has a primary location of Madrid or Barcelona (Spain). This is a hybrid role.

Role Summary

As a Senior Scientist in the Workflow, Applications and Plug-ins team within Data, Data Science and AI Org, you will lead the technical and product evolution of reusable GenAI-enabled content-authoring workflows across R&D, spanning therapeutic-area document generation, regulatory authoring, scientific content workflows and future integration with broader dossier and submission processes.

The role will help establish a reusable document-authoring capability on an internally built Agentic Platform rather than creating isolated solutions for individual document types.

Key Responsibilities

• Lead technical strategy and implementation of GenAI-enabled document-authoring workflows.
• Translate individual document workflows into reusable authoring capabilities and identify document-specific versus enterprise-common logic.
• Develop roadmap and requirements across multiple document classes and R&D functions.
• Establish patterns for evidence retrieval, grounding, drafting, citation, structured content, review and revision.
• Partner with Data teams to define source-data requirements and enterprise data connectivity.
• Partner with Evaluation & Quality to establish content-quality, faithfulness, traceability and regulatory-readiness evaluation.
• Integrate reusable QC/content-review capabilities into authoring workflows.
• Evaluate where external vendor capabilities can be consumed as modular services rather than forcing end-to-end vendor architectures.
• Work with Foundation Platform Team to identify reusable plugin and platform requirements generated from document-authoring use cases.
• Provide technical leadership to engineers, contractors, domain SMEs and federated Data Science partners.
• Drive workflows from prototype toward scalable enterprise capability.

Required Qualifications

• Master's degree in AI/ML, Computer Science, Engineering, Bioinformatics, or related field with 2+ years of hands-on experience in GenAI Science/Engineering.
• Hands-on experience with multi-agent frameworks such as LangGraph, DSPy, memO, or similar architectures.
• Strong proficiency in Python and modern deep-learning frameworks (PyTorch, TensorFlow).
• Experience building retrieval-augmented generation (RAG) systems, including chunking, embeddings, vector databases, and reranking.
• Knowledge of advanced mathematical concepts such as uncertainty quantification, probabilistic modelling, or information theory.
• Experience implementing structured generation, schema enforcement, and model/tool orchestration for complex workflows.
• Positive, motivated, collaborative approach with the ability to work independently and within a multidisciplinary environment.

Preferred Qualifications

• Understanding of the drug development pipeline, regulatory submissions, and biological or chemical data types.
• Familiarity with scientific literature analysis, knowledge extraction, and structured content generation.
• Experience in QC systems, verification agents, or regulatory document automation.
• Experience fine-tuning LLMs for specialised domains and deploying AI systems in cloud environments (AWS or Azure).
• Strong understanding of statistical validation methods for AI-driven workflows.
• Experience with Git-based development and CI/CD pipelines.

Integrity, innovation, collaboration, and responsibility are at the heart of everything we do. We foster an inclusive environment where diverse perspectives drive breakthrough solutions.
