TL;DR · Senior Scientist, Data Science, GenAI

JOB TITLE: Senior Scientist, Data Science, GenAI - R&D DDSAI - Therapeutics Development & Supply (TDS) The R&D Data Science organization is seeking a Senior Scientist to design, develop, and deploy AI and generative AI systems to accelerate scientific, regulatory, and technical workflows within Therapeutics Development & Supply. This hands-on role involves building LLM applications, agentic workflows, and automation solutions for document authoring, knowledge retrieval, and technical decision support. You will utilize Python, retrieval-augmented generation, embeddings, vector databases, and open-source agentic frameworks like LangGraph, DSPy, and mem0. The work requires applying software engineering practices and responsible AI frameworks within a regulated GxP environment. You will collaborate with CMC, quality, and scientific stakeholders to solve complex pharmaceutical product development challenges, ensuring all AI components meet established evaluation standards for robustness, traceability, and content safety.

What you'll do

  • Develop, test, and deploy AI solutions for documentation, knowledge retrieval, and decision support within the TDS ecosystem.
  • Build and test components of agentic AI workflows to coordinate models, tools, and data across supply chain processes.
  • Implement reusable AI capabilities using established DDSAI architectures and platform standards.
  • Translate stakeholder needs into technical AI requirements for regulated environments.
  • Apply evaluation frameworks to assess LLM systems for traceability, robustness, uncertainty, and usability.
  • Follow responsible AI practices including human-in-the-loop validation, risk assessment, and content safety governance.
  • Apply software engineering practices such as modular design, testing, and lifecycle management to all code.
  • Communicate implementation progress, system limitations, and risks to both technical and non-technical stakeholders.

What we're looking for

  • Degree in Engineering, Data Science, Life Sciences, Computer Science, or related field.
  • Advanced degree preferred.
  • 1–3 years of hands-on experience developing AI, NLP, or machine learning solutions, including practical experience applying large language models (LLMs).
  • Working knowledge of Pharmaceutical Product Development, including Chemistry, Manufacturing and Controls (CMC).
  • Proficiency in Python, with experience developing, testing, and documenting code.
  • Strong communication skills, with the ability to explain technical topics to non-technical stakeholders.
  • Exposure to open-source agentic frameworks (e.g., LangGraph, DSPy, mem0) (preferred).
  • Familiarity with retrieval-augmented generation, embeddings, vector databases, and model evaluation (preferred).
