Department CMC

Key Responsibilities The Senior Scientist for Mammalian Cell Line Development will bring experience and a strong understanding of developing and expressing mammalian cell lines for the production of complex biotherapeutics. For this lab-based role in the Process Development CMC group, you will develop and optimise mammalian cell lines for robust protein production of emerging drug candidates and reagents. The ability to plan and execute lab investigations independently and efficiently is key, along with analysis, interpretation and presentation of data. Collaborative teamwork across CMC and with research is essential, coupled with excellent communication skills.

To design and conduct experimental investigations enabling the advancement of the Company pipeline, process, or technology capabilities, proposing improvements for consideration by colleagues and managers. Supporting cell line development and upstream process development within CMC and supporting technical oversight of external cell line development and establishment in GMP manufacturing, ensuring regulatory compliance.

Key Responsibilities – All Scientists

Conducting experiments, observing, interpreting, and responding to results.
Maintaining and increasing technical knowledge in relevant fields through self-study, observation and attending relevant conferences or training courses.
