Scientist, Protein Expression & Purification
On-site · Lausanne, Vaud, Switzerland
Job Summary
Own mammalian protein expression and purification (CHO/HEK, transient and stable) and turn expression into a robust, automated, high-throughput capability. Lead purification across modalities (Protein A, IEX, SEC) and ensure quality of produced proteins. Partner with lab automation to scale workflows onto automated systems and reduce manual, person-dependent steps. Work with the software team to track samples and process parameters, making production yields and quality observable and improvable. Set the quality bar and troubleshoot failures across biology, reagents, and process. Collaborate with automation engineers and software teams to integrate data-driven production improvements.
Required Qualifications
- Deep, hands-on expertise in mammalian protein expression and purification — CHO/HEK, and the full path from construct to purified, characterized protein.
- Applied industry experience in production or industrial settings where yield, reproducibility, and turnaround mattered at scale.
- Track record of making production reliable — titer optimization, scale-up, and consistent quality.
- Builder who moves fast and stands up production capabilities; not just following fixed protocols.
- Interdisciplinary collaboration with automation engineers and software people; view automation and data as core to production.
- Data fluency (scripting, tracking and analyzing process data) is a strong plus.
