The company

Our client is a professional Pharmaceutical organisation, based in Zuid-Holland Netherlands. The company is dedicated to bringing meaningful innovation to global health. Our teams focus on the discovery, development, manufacture and marketing of vaccines and antibodies to protect people worldwide from infectious diseases.

In the organization entrepreneurial people are working in a dynamic culture in which innovation and a 'can do' state of mind are the central points. In order to strengthen our team we are continuously looking for enthusiastic, talented people who have the ambition to develop themselves and can be of value to the company and the team.

The Bacterial Vaccines department is working on the discovery and early development of novel vaccines for bacterial infectious diseases. It strives to address unmet medical needs, such as bacteremia (sepsis), meningitis, and respiratory tract and nosocomial infections. Projects at the Bacterial Vaccines department are primarily structured on scientific and technical collaboration with external biotechnology partners (governmental and industrial) that are innovative leaders in their field. This working process includes ‘state of the art’ vaccine discovery, with subsequent in vivo evaluation of these vaccine candidates in animal models for immunogenicity and/or efficacy. In addition, manufacturing processes are optimized and established, and the resulting clinical trial material is evaluated in human clinical studies.

Role description

The Bacterial Vaccine department is seeking a talented Associate Scientist (M.Sc. or B.Sc. with equivalent experience) to join the Biochemical assays and Antigenicity Screening group.
