Why this role is important for CPI’s work

CPI has an opportunity for two experienced Scientists to join the established Downstream team. We are looking for enthusiastic and experienced life scientists with a firm understanding of downstream processing of biopharmaceuticals, which can be applied to current and future projects in the fast-moving, collaborative workspace at CPI.

The role will be based at the Biologics business unit in Darlington, where the work supports clients and partners in developing expression systems and processes for their products, including downstream process development using high-throughput screening technology and process scale up for proof-of-concept studies and material supply. With an ever-expanding portfolio of projects in delivery and in the pipeline, which span across a breadth of expression systems, product types and customers, it is a great opportunity to be a part of the future development of the Downstream team.

CPI’s Biologics technical group works on a varied portfolio of projects, working with a wide range of products including monoclonal antibodies, viral vectors, recombinant proteins, microbial therapeutics and synthetically produced nucleic acids using conventional and advanced manufacturing approaches. The work of the group is diverse, examples including: 


To have and continuously develop a good knowledge/​expertise relevant to downstream processing of biopharmaceuticals such as proteins, viral vectors, and nucleic-acid based products expressed in mammalian, bacterial, insect, yeast cells and/​or cell-free systems. Your knowledge/​expertise should be both practical and theoretical in areas such as:

  • Theoretical and practical knowledge in Biochemistry, Biologics Purification, Biochemical Engineering and relevant analytical techniques.
  • Lead and deliver experimentation to develop and optimise recovery and purification processes for the manufacture of traditional and novel biopharmaceutical products.
  • Application of techniques for the analysis of proteins and other biologics. 
  • Application of experimental design and statistical concepts to experimental planning.
  • Use and application of computer systems and software for data acquisition and analysis.
  • Document writing, data interpretation, presentation and statistical analysis.
  • Application of your broad scientific knowledge to projects and client programs.
