• Design, plan, and execute upstream process development studies with minimal supervision.
• Apply QbD and DoE approaches to process optimisation and characterisation.
• Perform mammalian cell culture experiments using shake flasks, Am  systems, and laboratory-scale bioreactors.
• Support scale-up, scalability assessments, process troubleshooting, and technology transfer activities.
• Utilise automation and high-throughput technologies to improve workflow efficiency.
• Contribute to evaluation of emerging technologies and platform improvements.

• Analyse and interpret experimental data using appropriate statistical approaches.
• Generate accurate, high-quality scientific data and documentation.
• Prepare technical reports, protocols,presentations, and project summaries.
• Communicate findings and recommendations to project teams and stakeholders.
• Collaborate with Cell Line Development, Analytical Sciences, Downstream Development, Manufacturing and external partners.
• Represent Upstream Process Sciences incross-functional project teams.
• Maintain accurate laboratory records and electronic laboratory notebooks.
• Ensure compliance with HSE, GMP/GSP, quality systems, and data integrity requirements.
• Participate in continuous improvement initiative sand laboratory best practices.

• MSc in Biotechnology, Biochemical Engineering,Chemical Engineering, Molecular Biology, Cell Biology, Bioprocess Engineering,or related discipline. or BSc with relevant industrial experience.

• Experience in mammalian cell culture and biologicsprocess development.
• Hands-on experience with CHO cell culture and therapeutic protein production.
• Experience operating Am  and/or laboratory-scale bioreactor systems.
• Knowledge of cell culture scale-up principles and process characterisation.
• Experience applying DoE and statistical data analysis tools.
• Strong scientific problem-solving and troubleshooting skills.
