• Lead and participate in experimental design, execute planned experiments, and optimize process steps for the target process scale, including laboratory- and occasional pilot-scale conjugation reactions, chromatography, and TFF filtration.
• Lead the design and execution of development studies to identify appropriate conditions and establish ranges for critical process parameters across chromatography, filtration, and conjugation reaction process steps.
• Record and analyze experimental data, verify data integrity and accuracy, report and summarize findings for the project team, draft technical documents, and perform technology transfers to collaboration partners.
• Work collaboratively in a team environment and contribute independently to meet project timelines and objectives.

• PhD (preferably in Chemical Engineering or Biological Sciences or Biochemistry or other equivalent major) with at least 3 years of relevant post-doctoral experience OR MS (Preferably in Chemical Engineering or Biological Sciences or Biochemistry or other equivalent major) and with at least 12 years of relevant experience OR a BS (preferably in Chemical Engineering or Biological Sciences or Biochemistry or other equivalent major) and with at least 15 years of relevant experience is required. 
• Knowledge and hands-on laboratory experience in downstream processing, purification of antibodies/recombinant protein therapeutics, and production of bioconjugates (such as tLNP, ADC or other equivalent conjugates), in particular chromatography, filtration and conjugation, are required.
• Exposure to analytical method development for in-process methods is preferred.
• The candidate must be highly organized and capable of managing/pursuing multiple projects independently.
• Good written and verbal communication skills are required.
• Experience maintaining written records of work in the form of (electronic) notebooks, technical reports and protocols is required.
• Data reporting, ability to present findings to management, and experience with team-based collaborations is a must.
• Occasional weekend work may be required.
