Key Responsibilities Synthesis, purification, and characterization of antibody oligonucleotide conjugates (AOCs) and antibody drug conjugates (ADCs) on mg to gram scale under minimal supervision. Design and execute engineered cysteine antibody conjugation workflows Optimize reaction stoichiometry, linker chemistry, and reaction conditions to improve peptide-to-antibody ratios and product homogeneity. Development, optimization, and validation of conjugation protocols specifically for antibody oligonucleotide conjugates. Optimization and validation of formulation buffers for bioconjugates. Application and refinement of automated techniques for AOC/ADC synthesis and purification. Collaboration with cross-functional teams to advance AOC discovery programs from conceptualization to early development. Develop and optimize peptide–antibody conjugation strategies Optimize reaction stoichiometry, linker chemistry, and reaction conditions to improve peptide-to-antibody ratios and product homogeneity. Investigate and mitigate sources of conjugation heterogeneity such as over-reduction, disulfide scrambling, hydrolysis, and aggregation. Apply diverse conjugation chemistries including thiol-reactive linkers, maleimide coupling, NHS ester chemistry, and bioorthogonal click chemistry (e.g., azide–alkyne cycloaddition). Characterize conjugates using analytical techniques including SEC-HPLC, LC-MS (intact/reduced), RP-HPLC, and SDS-PAGE. Access external innovation to complement internal efforts
Qualifications Bachelor’s Degree or equivalent education and typically, 12 years of experience, Master’s Degree or equivalent education and typically 10 years of experience, PhD and typically 4 years of experience. Expertise in the discovery, design, synthesis, and purification of Antibody Oligonucleotide Conjugates (AOC), including familiarity with associated chemistries and analytical methods. Hands-on experience with relevant analytical techniques such as HIC-HPLC, SEC, IEX, RP-HPLC, and capillary electrophoresis techniques (e.g., CE-SDS, icIEF). Proven problem-solving skills, motivation, enthusiasm, attention to detail, and the ability to thrive in a fast-paced, cross-disciplinary team environment. Superior written and oral communication skills, with a strong record of collaboration and innovation. Familiarity with biorthogonal conjugation techniques and next-generation site-specific conjugation platforms.
