About the Role:

We seek a Bioconjugation Sr. Scientist to join our Bioconjugates Research Group. The successful candidate will contribute to the design, generation, and characterization of novel bioconjugate modalities, including antibody-peptide conjugates (APC), antibody-oligonucleotides conjugates (AOC), and antibody-drug conjugates (ADC). Your expertise in protein and antibody conjugation will enable you to have a significant impact on Neurocrine’s pipeline of innovative therapeutics.

Your Contributions (include, but are not limited to):

  • Carry out laboratory functions, plan and design experiments, and apply technical knowledge and skills to achieve project goals in a precise and timely manner

  • Design, synthesize, and characterize antibody conjugates using state-of-the-art bioconjugation methods, purification processes, and biophysical techniques

  • Optimized conjugation protocols using novel chemistries and techniques for a variety of bioconjugates modalities such as peptide-antibody (APC), oligonucleotides-antibody (AOC) and small molecule antibody (ADC) conjugates. Experience with different conjugation strategies, such as stochastic vs site-specific conjugation, is desirable

  • Identify and troubleshoot critical issues within conjugation processes, resolving them promptly to ensure consistent progress and quality

  • Collaborate cross-functionally with chemists and other teams to design and establish linker-payload biologic SAR (structure-activity relationships), supporting scientific discovery and project progression

  • Tracks progress against the timelines of ongoing projects, ensuring timely delivery of results and providing regular updates to project teams and stakeholders

  • Effective communication of scientific rationale, results, and interpretation at project, team and departmental meetings, contributing to strategic discussions

  • Establish and maintain excellent working relationships with critical collaborators throughout the company

  • Maintains accurate and well-organized lab notebooks and batch
