Lead Scientist - R&D Purification

Lonza

Slough, United Kingdom

Join Lonza’s cutting-edge R&D team in Slough and play a pivotal role in advancing next-generation purification technologies. This is a hands-on scientific role where you will drive innovation in downstream processing and contribute to the development of intensified, scalable purification solutions for biologics.

What you will do

• Design and execute experimental studies to develop and optimise purification processes for biologics;
• Evaluate and implement advanced chromatography and filtration technologies for intensified downstream processing;
• Develop scalable purification workflows, including chromatography and tangential flow filtration (TFF);
• Analyse complex datasets using statistical tools to generate data-driven insights and recommendations;
• Author high-quality technical reports and present findings to cross-functional stakeholders;
• Collaborate with multidisciplinary teams across R&D, MSAT, and manufacturing to enable technology transfer;
• Provide scientific leadership, contributing to innovation, troubleshooting, and continuous improvement initiatives.

What we are looking for

• Degree in Biotechnology, Chemistry, Chemical Engineering, or a related field (advanced degree preferred);
• Strong hands-on experience in protein purification, including chromatography (affinity, ion exchange, HIC, mixed mode);
• Knowledge of downstream processing techniques such as TFF, UF/DF, and filtration operations;
• Experience developing scalable purification processes for biologics (e.g. monoclonal or bispecific antibodies);
• Strong data analysis skills with the ability to interpret complex datasets and draw clear conclusions;
• Ability to independently design experiments and apply scientific problem-solving approaches;
• Excellent communication and collaboration skills, with the ability to work effectively across teams.
