Location:
On-site Hunt Valley, MD. Relocation assistance is NOT provided. Must be legally authorized to work in the United States without sponsorship. Must be able to pass a comprehensive background check, which includes a drug screening.
Discover Impactful Work:
We are looking for a motivated individual to join our Global Bioproduction Analytics Team. This position supports a cross-functional team working toward the design and commercialization of new cell culture media and media supplement products. The successful candidate will have extensive experience with high-resolution LC-MS workflows for large molecules, including monoclonal antibodies (mAbs), bispecific antibodies (bsAbs), antibody-drug conjugates (ADCs), and other therapeutic proteins. This role requires strong analytical problem-solving skills, the ability to interpret complex datasets, and close collaboration with cross-functional teams to deliver high-quality analytical solutions that accelerate cell culture media development.
What You Will Do:
Develop, optimize, and execute LC-MS methods for the characterization of therapeutic proteins using high-resolution mass spectrometry platforms. Analyze and interpret complex mass spectrometry datasets to identify and characterize post-translational modifications (PTMs), sequence variants, chain mispairing, and structural attributes of monoclonal antibodies, bispecific antibodies, ADCs, and other protein therapeutics. Characterize critical quality attributes (CQAs), including glycan heterogeneity, charge variants, aggregation, and molecular integrity using orthogonal analytical techniques. Perform intact mass analysis, middle-down characterization, peptide mapping, and other large molecule MS-based workflows. Prepare clear, accurate, and scientifically sound reports, technical presentations, and analytical documentation for internal and external stakeholders. Troubleshoot analytical methods, investigate unexpected results, and recommend scientifically justified solutions. Perform routine testing, maintenance, troubleshooting, and performance verification of mass spectrometers, liquid chromatography systems, and associated instrumentation to ensure reliable operation. Stay up-to-date with the latest technological and practical advancements in the field of analytical chemistry as they pertain to cellular processes.
