  • Serve as the primary technical contact and subject matter expert for downstream processing (DSP) in mammalian cell culture manufacturing within Ibex.

  • Lead technical transfer, scale-up, and implementation of downstream purification processes into clinical and commercial production facilities.

  • Perform technical troubleshooting, root cause analysis, and lead complex investigations for process deviations and yield non-conformances.

  • Analyze manufacturing data, monitor process consistency, and drive continuous process improvements and optimization initiatives.

  • Collaborate cross-functionally with Operations, Quality Assurance, MSAT Lab, and customers to ensure smooth manufacturing execution and alignment.

  • Author, review, and approve critical technical documentation including batch records, campaign summaries, and regulatory filings.


What we are looking for:

  • Bachelor's, Master's, or PhD degree in Biotechnology, Chemical Engineering, Biochemistry, or a related scientific discipline.

  • Proven experience in downstream processing (purification) for mammalian cell culture biopharmaceutical manufacturing or MSAT environments.

  • In-depth technical expertise in unit operations such as chromatography, filtration (UF/DF, TFF, viral filtration), and process scale-up.

  • Strong problem-solving, analytical, and structured investigation skills in a GMP manufacturing environment.

  • Excellent communication skills and fluent in English; German language skills are an advantage.

You will feel at home at Lonza if you:

• Take ownership, step forward, and enjoy meaningful responsibility

• Love solving problems and thrive in a complex, fast-moving environment

• Are curious, always looking to learn and improve

• Work collaboratively, contributing to something bigger than yourself

• Are motivated to make a difference through work that impacts customers and their patients
