Within the Biodevelopment Process Development group, will be primarily responsible for developing purification processes for a variety of therapeutic candidate proteins including monoclonal antibodies and Fc fusion proteins. Scope of work will include, but are not limited to, protein purification, biochemical and biophysical characterization of proteins, novel purification technologies, purification process development, data analysis and project reporting. Execution of client project according to budget and timelines given to the project team.


* 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.

* To support follow-up and troubleshooting on analytical methods.

* Provide expertise and insight to guide development of appropriate purification methods

* Develop novel purification processes as well as using standard methods to purify proteins from the mg to gram scale. Processes will be multiple steps and must provide necessary clearance of viruses, endotoxin, and host cell proteins and DNA.

* Perform, develop and optimize robust, efficient, scalable strategies for improving process performance. Activities will include small-scale studies and pilot scale purification studies.

* Apply DOE methods to purification activities


* Engineering/Master degree (PhD preferred) in biotechnology with 5+ years in the biopharmaceutical industry
