About the Role
This role is for a senior industry scientist responsible for delivering antibody programs for customers, with a focus on CHO cell-line development and upstream process development. The position involves owning the scientific delivery of customer programs, defining development plans, designing experiments, interpreting data, and communicating results.
Responsibilities
- Owning the scientific delivery of customer antibody programs from cell-line strategy through media and feed development, bioreactor confirmation and a clear scale-up package.
- Designing and driving CHO cell-line development: host and vector choices, transfection, pool generation, clone selection, screening, stability assessment and cell-banking strategy.
- Developing and optimising basal media and feeds using disciplined, decision-oriented experiments grounded in cell metabolism and process biology.
- Translating customer goals, target product profiles and timelines into development plans with clear milestones, risks, decision gates and data packages.
- Designing DoEs and run plans across high-throughput screens, 300 mL bioreactors and 3 L confirmation runs; setting parameters, sampling plans and analytical requirements.
- Diagnosing the causes of weak growth, viability, productivity or product quality - separating cell-line, media, feed and process effects and choosing the next experiment quickly.
- Working closely with analytics and downstream teams so upstream decisions reflect titre, product quality, impurity burden and the needs of the complete manufacturing process.
- Communicating directly and credibly with customers: explaining results, trade-offs, uncertainty and the recommended path forward in clear scientific and commercial language.
- Delegating routine execution to operations technicians while staying close enough to the work to protect scientific quality and stepping in hands-on when the biology demands it.
- Turning lessons from individual programs into reusable platform rules, operating windows and better development workflows.
Requirements
- At least five years of relevant industry experience required in addition to the PhD.
- Delivered mammalian cell-culture or antibody-development programs in a biotechnology or biopharmaceutical setting; academic experience alone is not sufficient.
- A track record of personally taking antibody-producing CHO cell lines from transfection or pool generation through clone selection, stability assessment, productivity optimisation and banking.
- Substantial experience developing or optimising cell culture processes.
- A record of designing rigorous experiments and making sound decisions from incomplete data across multiple concurrent development programs.
- Experience owning program outcomes and communicating directly with internal or external customers, not only completing an assigned scientific work package.
- Strong written and verbal communication skills.
- High pace, high ownership and low ego; comfortable being accountable for delivery in a small team and remaining hands-on when needed.
