Job Description

• Design fit-for-purpose purification experiments according to the stage of development
• Ensure scientific evaluation of impact of deviations to Downstream validation studies
• Compile and analyze experimental data to generate process knowledge and decide on next steps
• Write development and validation reports and ensure their timely delivery
• Prepare and present project updates to global project team and to upper management
• Ensure a continuous improvement within Downstream process development activities
• Represent & promote E2E and Biodevelopment activities (presentations, congresses, events)
• Technical lead on the overall projects (supervises Downstream processes development and implementation of new methods and services)
• Technical leader for equipment, technologies for Downstream process development
• Responsible for activities ranging from protein purification, filtration, biochemical and biophysical characterization of proteins: –
• Execute routine protein purification with affinity, size exclusion, ion exchange, and hydrophobic interaction chromatography using AKTA systems (Unicorn software)
• Perform analyses including but not limited to SDS-PAGE, SE-HPLC, LAL, host cell-DNA, host cell protein, as necessary
• To develop, validate and transfer robust analytical methods required for successful drug development and manufacturing.
