You will apply state-of-the-art mass spectrometry and analytical technologies to characterize therapeutic protein candidates, with a focus on critical quality attributes and process development, while collaborating closely with cross-functional teams to coordinate samples, study activities, priorities, and timelines. Preferred / nice-to-haves: Experience with advanced mass spectrometer platforms (e.g., Orbitrap, Q-TOF, and triple quadrupole), liquid chromatography, and relevant data processing software (e.g., Xcalibur, Protein Metrics, ChemDraw, Skyline, Proteome Discoverer, and other related analytical tools).
