Senior Scientist, Research Science

Job Description Senior Scientist – NAMs & Investigative Toxicology Position Summary We are seeking a highly motivated Ph.D.

-level scientist to join the In Vitro Toxicology group within Nonclinical Drug Safety. The successful candidate will develop and apply advanced in vitro models, including 3D tissue models, organoids, and microphysiological systems (MPS), to address key challenges and advance New Approach Methodologies (NAMs) in nonclinical safety assessment. We are looking for a scientist who combines strong experimental skills with strategic thinking, intellectual curiosity, emotional intelligence, effective communication, and a commitment to continuous learning.

• Develop, qualify and implement advanced in vitro assays and human-relevant model systems to support investigative toxicology and nonclinical safety assessment.
• Design and execute mechanistic studies to evaluate drug effects, toxicity mechanisms, and translational biomarkers.
• Synthesize complex scientific data and communicate key insights clearly to multidisciplinary teams, leadership, and non-technical stakeholders.
• Evaluate emerging technologies and identify opportunities to advance scientific capabilities and decision-making.
• Collaborate across internal and external partners in discovery, safety assessment, drug metabolism, and translational sciences.
• Contribute to scientific strategy related to NAMs, MPS, and next-generation safety assessment approaches.
• Publish findings and represent the organization through scientific presentations and collaborations.

• A strategic thinker who connects scientific activities to broader organizational and drug development objectives.
• An active listener who seeks to understand different viewpoints before drawing conclusions.
• Intellectually curious and motivated by continuous learning in a rapidly evolving field.
• Emotionally intelligent, self-aware, and effective at building trust-based relationships.
