Organic, Medicinal, or Analytical Chemistry

Janssen Research & Development seeks to bring innovative and effective treatments in therapeutic areas of high unmet medical need. The Janssen campus in Beerse, close to Antwerp, (Belgium) has a unique ecosystem covering the complete drug development life cycle, with all capabilities from basic science to market access on one campus. Our discovery chemistry group focusses on developing innovative small molecule therapeutics to treat diseases like Alzheimer’s disease, cancer, and infectious diseases, including Corona.

In order to further strengthen the scientific teams working on our small molecules portfolio, we are recruiting assistant and associate scientists with differentiated expertise:

The medicinal chemistry teams design and synthesize novel molecules as potential drug candidates and work closely together with colleagues from the associated biology teams and with several internal and external partners aiming to progress the most innovative science. The work will involve designing and executing challenging multi-step organic synthesis, compound purification and structure determination, maintaining state-of-the art scientific knowledge as well as originating and defending novel ideas in new and on-going projects.

The analytical chemistry team supports the medicinal chemistry team with modern analytical technologies, including gas, liquid and supercritical fluid chromatography hyphenated with mass spectrometry (GC-MS, UPLC-MS, SFC-MS), nuclear magnetic resonance spectroscopy (NMR) and advanced purification technologies focused on chiral, achiral and high throughput purifications (HTP) in a highly automated environment.

Our parallel medicinal chemistry team develops and optimizes synthetic methods to execute automated library synthesis including flow chemistry. The team works closely together with the medicinal chemistry project teams in the identification and optimization of new molecular entities.
