You will be working with everything from animal to plant cells; adherent to suspension cultures; primary cells to iPSCs. You don't need to be an expert in all, but you need to be able to adapt your skillset to each given challenge. This role will utilise your skills or understanding in: bioreactor monitoring and control. intensified bioprocessing, including perfusion, semi-continuous and continuous bioprocessing. bioprocess development across methodologies. scale-up from bench scale to pilot-scale and above. safe working practices in a life science lab. leading a team of people to deliver project goals. The Candidate Profile You will likely have 5-10 years of experience working in cell-culture bioprocess development or commercial biomanufacturing, but we value quality of experience over quantity. You should have experience working in industry, with a commercial mindset and understanding of project management principles. You'll ideally have had experience operating 1,000L bioreactors. You should have experience being a leader and as line manager. You will have had experience adhering to (and ideally leading) quality and control processes to ensure production of safe commercial products. You'll need excellent organisational skills and a great attention to detail with a focus on data quality and integrity. You will have experience utilising a quality management system or electronic lab notebooks. Understanding and knowledge of CDMO business model, or experience delivering and managing customer projects is a plus. You'll need to be a genuine team-player who asks for help when it's needed and offers help when it isn't.
