What you will do

Let’s do this. Let’s change the world. The Pharmacokinetics & Drug Metabolism and Bioanalytical Sciences (PKDM-BA) organization is seeking to fill a Sr. Principal Scientist position in our Immunogenicity Bioanalytical Sciences (IGBA) group. In this vital role you will support the design, development, validation, and implementation of assays for the detection of binding and neutralizing anti-drug antibodies (ADAs & NAbs) for Amgen’s large molecule/protein therapeutics to support GLP preclinical and regulated clinical studies. Such molecules will inherently be diverse in nature and will require technical expertise in the implementation of suitable and innovative immunogenicity methods in accordance with global regulatory guidelines.

This role will involve close collaboration with representatives from the drug development team, research groups, and compliance to ensure suitability of the assay format for the therapeutic program. You will work closely with an outsourcing team for the transfer of assays to global bioanalytical CROs. You will also be responsible for contributing to regulatory filing documents and for providing responses to questions received upon regulatory review.  Given the breadth of projects, this role will involve highly multidisciplinary interactions with scientists across research and development at Amgen and will provide an opportunity to supervise or mentor laboratory staff.

Key Responsibilities:

• Provide scientific and strategic leadership for immunogenicity assay development, validation, transfer, and implementation across nonclinical and clinical programs.
• Serve as a senior subject-matter expert for ADA, NAb, drug-tolerant, cell-based, and predictive immunogenicity assay approaches.
• Apply deep knowledge of global regulatory guidance, GLP/GCP expectations, and statistical assay validation principles to guide program decisions.
• Lead complex data interpretation, troubleshooting, and risk assessment to support immunogenicity bioanalytical strategy.
• Provide scientific oversight of  assay transfers to CROs, lead troubleshooting efforts while ensuring scientific quality, compliance, and timeline delivery.
• Influence cross-functional program teams and senior stakeholders in a matrixed environment.
