Scientist Formulation & Dowstream process xNA – Exothera

The formulation and DSP (downstream process) Scientist is responsible for the process adaptation and project execution in the scope of his/her activity. 

He/she acts as an expert in the formulation development of nucleic acid (LNP) including DSP technology (such as UF, Chromatography, and filtration).

He/she is responsible for the process transfer and execution supervision from non-GMP to GMP environment.

He/she works in close collaboration with the Technical Lead, the head of development and production, the analytical science/ QC team, the project leaders, and QA.


  • Design and execute innovative formulation and downstream process development for xNA vaccine, gene therapy, and biosimilar applications. 
  • Deliver technical expertise on one typical DSP unit operation. (such as TFF, depth filtration, chromatography) and formulation of LNP.
  • Develop detailed experimentation protocols and execute the planning/organization of the experiments in his/her scope of activities
  • Propose creative technical solutions to meet the project’s goals 
  • Review run forms and raw data.
