Scientist, Pharmacokinetics

Job Description The Drug Metabolism and Pharmacokinetics (DMPK) group within the PDMB function is seeking a highly motivated, collaborative scientist to support mass spectrometry-based immunogenicity assessment. The successful candidate will contribute to the execution of MHC-Associated Peptide Proteomics (MAPPs) studies and related LC-MS workflows used to characterize antigen presentation and support biologics, conjugates and peptides programs. The ideal candidate will primarily perform laboratory-based activities and be responsible for executing cell-based and immunoaffinity workflows, preparing samples for LC-MS analysis, maintaining laboratory instrumentation, and generating high-quality experimental data. The candidate will work in a multidisciplinary environment alongside scientists in immunology, bioanalysis, and mass spectrometry and will have opportunities to present findings at departmental meetings and contribute to scientific publications and presentations. Primary Activities Execute MAPPs (MHC-associated peptide proteomics) experiments to support immunogenicity risk assessment of therapeutic candidates. Maintain and expand human cell cultures, including routine cell maintenance, cell counting, viability assessment, and preparation of samples for downstream analysis. Perform immunoaffinity enrichment workflows, including antibody-based capture, antigen processing, and sample preparation for LC-MS analysis. Operate, maintain, and troubleshoot LC-MS instrumentation, including Orbitrap-based high-resolution mass spectrometry platforms . Generate, document, and review high-quality experimental data following established laboratory procedures and data integrity standards. Support optimization of sample preparation workflows and laboratory automation initiatives to improve efficiency and reproducibility. Maintain laboratory equipment, consumables, and records while ensuring compliance with safety and quality requirements.
