Our teams work together across 6 continents with passion and relentless curiosity in order to help patients at every stage of life. Joining our Healthcare team is becoming part of a diverse, inclusive and flexible working culture, presenting great opportunities for personal development and career advancement across the globe.

Start date : February 2026
Duration: 6 to 12 months
Location: Corsier-sur-Vevey, Suisse

Recombinant therapeutic proteins such as monoclonal antibodies (mAbs) are an important class of medicines serving patients most in need of novel therapies. The dominating production system for mAbs is a recombinant expression in mammalian cellular systems, mostly Chinese Hamster Ovary (CHO) cells, consisting of introducing a piece of DNA, coding for a mAb, into the genome of a host cell and an intensive selection process to obtain a drug-producing cell line.  Cell line development (CLD) is one of the most critical steps in the production of biological medical products. As a team dedicated to CLD innovation, we support the CLD activities by finding ways to identify better cell lines, with increased yield in a reduced timeframe. 
We offer an internship opportunity for a motivated individual to join our Technology Innovation team. 

Your role :

• As an intern, you will focus on investigating the possibility of implementing protein expression system that allows to uncouple the expression of mAb molecule from the protein expression pathways of CHO cells.
• You will be responsible for leading the generation of cell line stably expressing the exogenous RNA polymerase enzyme and evaluating its impact on the mAb yield.
• Practically, you will generate and characterize pools of modified cells and perform productivity assay to measure mAb titer.
• You will perform single cell cloning of best pools to obtain clonal cell lines
• You will screen clonal cell lines for expression of the enzyme using ddPCR.
• You will carry on a comparison between enzyme-expressing and control cell lines at different scales.
• The productivity assessment will involve the extensive use of the top-tier opto-microfluidic Beacon technology (Berkeley Lights), automate robotic platform and Ambr15.
• You will work closely with our team of experienced researchers to design and execute experiments, analyze data, and present findings to the wider team.

 Your Profile:

• Master/Engineer student in biology, molecular or cellular biology, biotechnology or related subject
• Strong interest in molecular/cellular biology and biotechnologies
• Basic/Beginner Programming Level: R or Python
• Language: Good French and English at least B2

What we offer: We are curious minds that come from a broad range of backgrounds, perspectives, and life experiences. We believe that this variety drives excellence and innovation, strengthening our ability to lead in science and technology. We are committed to creating access and opportunities for all to develop and grow at your own pace. Join us in building a culture of inclusion and belonging that impacts millions and empowers everyone to work their magic and champion human progress
