Sr. Principal Scientist - Project Toxicologist

What you will do

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 Senior 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.

• Mentor and support other Amgen scientists in the design execution and oversight of nonclinical studies.
