About the role

  • Develop and optimize N-glycan analysis workflows (HILIC-FLD, LC-MS, CE-LIF etc.), including sialic acid, NGNA, α‑Gal characterization and quantitation analysis.
  • Drive advanced structural elucidation of N-glycans using LC‑MS/MS, exoglycosidase sequencing, linkage analysis, monosaccharide analysis, and orthogonal structural tools.
  • Perform intact and subunit mass spectrometry, as well as glycopeptide mapping, to define glycan occupancy, site-specific heterogeneity, and structural impacts on the protein backbone.
  • Integrate glycan structural information with functional outcomes such as Fc receptor binding, Fc silencing/attenuation, CH2 stability, higher-order structure changes, aggregation, and immunogenicity risk.
  • Support glycosylation pCQA/CQA assessments, providing mechanism interpretation, structure-function justifications, and cross-program scientific guidance.
  • Support glycan-driven structural differences assessment in comparability studies.
  • Author technical reports, glycan characterization summaries, method development documentation, and regulatory submission content.
  • Continuously evaluate and implement emerging innovations in glycomics, glycoproteomics, and computational structure–function modeling.

Requirements

  • BS with +6 years of relevant experience in Analytical Chemistry, Glycobiology, Biochemistry, Biophysics, or related field OR MS with +4 years of relevant experience in Analytical Chemistry, Glycobiology, Biochemistry, Biophysics, or related field OR PhD with 0 years of relevant experience in Analytical Chemistry, Glycobiology, Biochemistry, Biophysics, or related field.
  • Hands-on experience with LC‑MS or MS/MS for glycan or glycoprotein structural characterization.
  • Strong analytical reasoning and the ability to interpret complex structure–function relationships.
  • Excellent communication skills and ability to work effectively in a cross-functional, matrixed environment.
Benefits
  • company-sponsored medical, dental, vision, and life insurance plans*
  • paid time off
  • discretionary annual bonus
  • discretionary stock-based long-term incentives (eligibility may vary based on role)
