• Monitoring and optimization of the internal CLD workflow, in particular the fed-batch process in miniaturized bioreactor systems (ambr15, ambr250) and shake flasks
• Experience in the establishment of cell banks (MCB, WCB) in accordance with GMP requirements, including cell bank documentation and qualification, is desirable
• Preparation, review, and approval of regulatory documents such as SOPs, qualification plans, and CLD CMC sections for regulatory submissions
• Analysis, interpretation, and presentation of analytical data from cell culture, fed-batch processes, and quality analytics — both internally and to customers and authorities
• Ensuring data integrity, traceability, and a high standard of scientific documentation quality
• Close collaboration with Process Development, Quality Assurance, Regulatory Affairs, and Project Management
• Continuous development of methods, workflows, and standards within CLD, including evaluation of new technologies and automation solutions
