The posting
LimmaTech Biologics AG, a wholly owned subsidiary of Eli Lilly and Company, is a Swiss based clinical stage biopharmaceutical company. We are advancing our vaccine pipeline to halt the increasing threat of global infections due to emerging antimicrobial resistance (AMR) and sexually transmitted diseases. Working at LimmaTech is a unique chance to be part of the development of life saving vaccines.
Are you excited about the opportunity to contribute to the development of early- to mid -stage vaccines by developing innovative protein purification processes using your technical and scientific skills? Would you like to be part of a team establishing scalable and GMP-compatible manufacturing processes to produce lifesaving vaccines? Then we want you to apply!
To strengthen our Downstream Processing (DSP) team, we are currently looking for a
CMC-Development Associate, DSP (100%)
to contribute to the development of robust and scalable manufacturing processes.
Your responsibilities
In this role, you will:
- Prepare, perform, and document DSP operations and experiments in accordance with established plans, timelines, and project priorities.
- Develop robust and scalable purification processes suitable for subsequent GMP manufacturing under the guidance of experienced team members, using state-of-the-art equipment such as FPLC systems, microfiltration, depth filtration, and tangential flow filtration (TFF) systems.
- Establish and execute experimental strategies to investigate chromatography methods and resins, filtration technologies, and critical process parameters, with the aim of identifying optimal purification conditions for novel products.
- Establish & perform in-process controls (IPCs) to characterize process intermediates and purified material to support process development and monitor purification performance.
- Evaluate and interpret experimental data and communicate results and conclusions in scientific meetings, presentations, and technical reports.
- Support technology transfer activities to contract manufacturing organizations (CMOs) throughout different stages of development.
- Help ensure that laboratories and equipment are maintained in a clean, safe, and fully operational condition in accordance with applicable safety and operational standards.
