ROLE SUMMARY

The incumbent will develop and perform glycoconjugate processes for manufacturing carbohydrate-based vaccines. Primary duties include development of new/novel conjugation methods, analysis of glycoconjugates, and optimization of conjugation process parameters including conjugation and purification. Experience in the preparation of glycoconjugates is highly desired. The individual will become a key contributor towards the early development and scale up of glycoconjugate vaccines. Careful documentation of work and presentation of data is required. All work is to be done in a compliant manner according to SOP guidelines and cGMP/GLP regulations, where applicable.

ROLE RESPONSIBILITIES

  • Develop, optimize and scale-up conjugation process for glycoconjugate vaccine candidates.
  • Independently plan and execute experiments for conjugate vaccine candidates, and lead the development on special projects, when required.
  • Presents periodic status update, discuss problems and proposed solutions in discussion with group members. Offers insights based on experience to group members to help solve problems.
  • Collaborate with colleagues within Vaccine Research and Development organization including Bioprocess Fermentation, Purification, Analytical, and Formulation Development groups.
  • Keep abreast of scientific/ technological development by participating in scientific meetings/ seminars and through regular scientific review. Utilize new technologies and establish those technologies to improve conjugation process development
