The successful candidate will bring deep technical expertise in ADC design and execution, demonstrate strong experimental rigor, and act as a collaborative scientific partner across discovery teams.

This position requires a hands-on scientist who can independently execute complex studies while contributing to broader platform strategy, intellectual property, and innovation. The individual will thrive in a highly interactive, fast-paced research environment and will be expected to influence project direction through high-quality data, clear scientific reasoning, and effective communication.

Responsibilities:

• Prepare, purify, and characterize the high-quality antibody-conjugates (ADCs, ARCs, DACs etc.) with a high degree of independence in support of discovery and development of programs.
• Work with the linker-technology and medicinal chemistry teams to design and optimize the linker-payload and its bioconjugation chemistry.
• Apply organic and bioconjugation chemistry principles to guide linker-payload SAR and improve stability, potency, and developability.
• Implement state of the art bioconjugation technologies (cysteine, lysine, site-specific and other) and utilizing novel chemistries to generate bioconjugates.
• Develop purification strategies (up to 200 mg) with affinity, ion-exchange, hydrophobic interaction, size exclusion, and tangential flow filtration.
• Perform comprehensive ADC characterization using UV-Vis, SEC, HIC, RP-HPLC, IEX, cIEF, and LC-MS.
• Engage with multidisciplinary teams across chemistry, biology, pharmacology, and CMC to design and interpret experiments.
• Maintain thorough documentation of experimental procedures in electronic notebook or database, writing of reports and technical documents.
• Maintain scientific and technical expertise through familiarity with scientific literature and attending conferences.
• Demonstrated record of scientific accomplishments and publications.

• Minimum 1-4+ years of independent, hands-on laboratory experience in an industrial or equivalent research setting (including post doc experience).

Additional Preferences:

• Experience with protein purification systems is preferred with hands-on experience and proficiency working with AKTA FPLCs.
• Deep expertise in bioconjugation technologies and experience working with high-potency payloads.
• Proven ability to collaborate effectively with small-molecule and biologics project teams to drive rapid scientific progress.
• Track record of scientific accomplishment, including publications, patents, or significant internal contributions.
• Excellent written and verbal communication skills, with the ability to clearly convey complex scientific concepts.
• Attention to detail, and ability to manage multiple priorities in a dynamic environment.
