• Develop reusable AI capabilities aligned with DDSAI AI/ML architecture and platform standards.
• Translate scientific, regulatory, and operational needs into scalable AI systems for regulated environments.

Technical Rigor & Responsible AI

• Establish evaluation frameworks for LLM systems, including rubrics, traceability, robustness, uncertainty, and usability.
• Apply responsible AI practices, including human-in-the-loop validation, risk assessment, content safety, and governance.
• Maintain strong software engineering practices, including modular design, testing, documentation, and lifecycle management.
• Contribute to best practices for LLM, RAG, and agentic AI systems across DDSAI and TDS.

Cross-Functional Collaboration

• Partner with regulatory, quality, CMC, scientific, and technical stakeholders to define use cases, validate outputs, and drive adoption.
• Collaborate with DDSAI AI/ML on infrastructure, architecture, evaluation, and reusable components.
• Communicate system behavior, risks, and tradeoffs to both technical and non-technical stakeholders.

QUALIFICATIONS

Required

• Degree in Engineering, Data Science, Life Sciences, Computer Science, or related field; advanced degree preferred.
• 3–5+ years of hands-on experience building and deploying AI, NLP, or generative AI solutions, including large language models (LLMs).
• Experience in Pharmaceutical Product Development, including Chemistry, Manufacturing and Controls (CMC)
• Strong proficiency in Python
• Strong communication skills, with the ability to explain technical topics to non-technical stakeholders.

Preferred

• Experience with open-source agentic frameworks (e.g., LangGraph, DSPy, mem0, etc.)
• Experience 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.
