Principal Scientist - Project Toxicologist

Let’s do this. Let’s change the world. In this vital role, you will serve as the primary interface between Translational Safety & Risk Sciences (TSRS) and cross‑functional project teams, from early discovery through post-marketing. TSRS at Amgen is seeking a Principal Scientist to serve as a Project Toxicologist and Subject Matter Expert, reporting to a Project Team Representative (PTR) Manager.

You will be responsible for developing and implementing fit-for-purpose nonclinical safety strategies built on a rigorous scientific foundation and aligned with regulatory expectations. As programs evolve, you will flexibly adapt strategies in response to emerging data, and project team needs while leading multidisciplinary TSRS teams.

As a PTR, you will partner closely with project teams developing innovative therapeutics across a range of modalities—including biotherapeutics (e.g. T cell engagers and antibody-drug conjugates), small molecules, targeted protein degraders, and other complex modalities (e.g. RNA-based therapies) for indications in inflammation, rare diseases, oncology, and cardiometabolic diseases, including obesity. PTRs are encouraged to develop subject matter expertise in a specific modality, therapeutic area, or sub-discipline within nonclinical safety (e.g. organ/system-specific toxicity).

Key responsibilities:

• Serve as a core toxicology and nonclinical safety representative on project teams, providing scientific leadership and regular updates to teams and management.
• Design, implement, manage and interpret nonclinical safety assessment programs in support of drug development candidates.
• Originate novel study designs and protocols to address complex scientific questions and develop integrated strategies to achieve project goals.
• Critically evaluate and interpret experimental data and author key sections of internal governance documents, INDs, BLAs, NDAs and other regulatory documents.
• Coordinate and collaborate with internal Amgen scientists and external partners to advance research and development programs.
• Mentor and support other Amgen scientists in the design execution and oversight of nonclinical studies.
• Represent Amgen on nonclinical safety topics in interactions with U.S. and international regulatory agencies and contribute to external industry initiatives aimed at advancing drug safety assessment paradigms.
