- Ion exchange chromatography (CEX/AEX/IEX)
- Hydrophobic interaction chromatography (HIC)
- Mixed-mode chromatography (MM) preferred
- Depth filtration
- Virus/sterile filtration
- Nanofiltration
- TFF / UF-DF
- Experience operating larger-scale bioprocess equipment, including chromatography systems and TFF skids.
- Ability to work hands-on in a primarily laboratory-based environment.
- Experience authoring SOPs, technical reports, and maintaining detailed ELN records.
- Strong troubleshooting, experimental design, analytical, planning, and scientific communication skills.
Key Responsibilities
- Perform and support scale-up protein purification processes from harvest through UF/DF.
- Prepare buffers at laboratory/pilot scale.
- Set up, operate, troubleshoot, and maintain chromatography systems, TFF skids, filtration systems, mixers, tanks, pumps, and single-use assemblies.
- Perform pre-run readiness activities, including equipment setup, column packing/qualification, buffer/media verification, and raw-material staging.
- Support GLP toxicology material production and transfers to GMP manufacturing for clinical material.
- Develop and maintain SOPs for laboratory equipment and processes.
- Document experimental/process activities in ELN and prepare technical reports.
- Present technical findings to project teams/stakeholders.
- Support establishment and operationalization of the new purification laboratory.
- Collaborate cross-functionally toward project timelines and deliverables.
Preferred Experience
- Antibody or antibody-like molecule purification.
- End-to-end purification experience from harvest through UF/DF.
- Pilot-scale experience, preferably 50 L–1,000 L bioreactor scale.
- Recent/current GMP or pilot-lab experience.
- Process development experience, including candidates with primarily bench-scale development experience.
- Hands-on experience with:
- ÄKTA Ready – primary system
- ÄKTA Process
- ÄKTA Avant
- ÄKTA Pure
