POSITION SUMMARY

The R&D Data Science organization is seeking a Senior Scientist, Data Science to contribute to the design, development, evaluation, and deployment of AI and generative AI systems that accelerate scientific, regulatory, and technical workflows across Therapeutics Development & Supply (TDS).

This hands-on individual contributor works across Product Development, Manufacturing, Clinical Supply Chain, Quality, and Digital and Data Science teams to develop LLM applications, agentic workflows, and AI-driven automation solutions specific to TDS. Key use cases include scientific and regulatory document authoring, evidence-based response generation, knowledge retrieval and synthesis, technical decision support, and workflow automation. Working with guidance from senior technical colleagues in DDSAI, the role delivers defined components and workflows within agreed priorities and milestones, using established architectures, reusable components, evaluation standards, and responsible AI practices. A successful candidate combines practical AI development skills with an understanding of pharmaceutical CMC development and seeks technical input on complex design decisions, risks, and delivery challenges.

KEY RESPONSIBILITIES

AI Solution Development & Delivery

• Develop, test, and support deployment of AI solutions for documentation, knowledge retrieval, evidence synthesis, and decision support in the TDS ecosystem, with guidance on solution design and implementation.
• Build and test defined components of agentic AI workflows that coordinate models, tools, data, and human review across multi-step scientific and supply chain processes.
• Implement and adapt reusable AI capabilities using established DDSAI AI/ML architectures and platform standards.
• Work with scientific, regulatory, and operational stakeholders and senior technical colleagues to translate defined needs into AI solution requirements and implementations for regulated environments.

Technical Rigor & Responsible AI

• Apply established evaluation frameworks for LLM systems, including rubrics, traceability, robustness, uncertainty, and usability; contribute test cases and analysis to improve these frameworks.
• Follow responsible AI practices, including human-in-the-loop validation, risk assessment, content safety, and governance, with guidance on identifying and escalating risks.
• Apply software engineering practices, including modular design, testing, documentation, and lifecycle management, with code review and technical guidance.
• Contribute implementation experience and evaluation findings to best practices for LLM, RAG, and agentic AI systems across DDSAI and TDS.

Cross-Functional Collaboration

• Work with regulatory, quality, CMC, scientific, and technical stakeholders to clarify use-case requirements, validate outputs, and support adoption.
• Collaborate with DDSAI AI/ML to use shared infrastructure, established architectures, evaluation methods, and reusable components.
• Communicate implementation progress, evaluation results, system limitations, and risks to technical and non-technical stakeholders; seek guidance when issues affect scope, design, or delivery.

QUALIFICATIONS

Required

• 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.

Preferred

• Exposure to open-source agentic frameworks (e.g., LangGraph, DSPy, mem0).

• Familiarity with retrieval-augmented generation, embeddings, vector databases, and model evaluation.

• Exposure to working in regulated environments (GxP)

• Familiarity with responsible AI frameworks, content safety practices, and AI governance in regulated environments.
