PsiOxus Therapeutics Ltd is an award-winning UK/US development stage biotechnology company developing novel therapeutics for the treatment of cancer, with a focus on immunotherapeutic approaches.  We have a first- generation oncolytic virus and three transgene-expressing T-SIGn cancer gene therapy candidates in Phase I/II clinical development, and are further developing our innovative platform technology and pipeline of new pre-clinical and research candidates.

We have an exciting new opportunity for a Scientist to join our CMC team.  In the role you will assist with the development of PsiOxus viral manufacturing processes and technology transfer to contract manufacturers.   This role will report directly into the Head of Manufacturing.

Key areas of responsibility will include, but are not limited to: 

  •      Development and optimisation of downstream processes including UF/DF and chromatographic techniques for the purification of proteins and viral candidates.
  •      Optimisation and scale-up of purification processes for transfer to a contact manufacturing organisation for GMP manufacture.
  •      Design and execute small scale shake flask experiments and bioreactor processes to optimise the upstream process for viral candidates.
  •       Investigate, develop and establish new methodologies in upstream and downstream purification.
  •       Assist in the technical transfer of processes to a relevant CMO.
  •       Perform product characterization and in process analysis.
  •       Produce well written, compliant & traceable laboratory notebooks and raw data files.
