Research Scientist I/II, Bioanalytical Sciences & Assay Development

JOB SUMMARY

We are seeking a highly motivated Research Scientist, Bioanalytical Sciences & Assay Development to join our drug discovery team. This scientist will develop and implement mass spectrometry-based assays and bioanalytical workflows supporting Hit Identification (HitID), ADME/DMPK characterization, and physicochemical property assessment. A key focus will be the development and application of MS-based screening approaches for HitID, including Affinity Selection Mass Spectrometry (ASMS) and other MS-based capabilities.

The ideal candidate will have a strong foundation in bioanalytical science, mass spectrometry, and assay development, with the ability to develop robust and scalable assays for small-molecule drug discovery. This scientist will work at the interface of experimental science, automation, and AI-driven molecular design, generating high-quality data that inform compound optimization and enable rapid design–make–test–learn cycles. This position will be based in our San Diego Headquarters.

KEY RESPONSIBILITIES

• Develop and implement MS-based assays and screening workflows for HitID, including ASMS and other MS-based approaches.

• Develop fit-for-purpose bioanalytical and bi
