As an (Senior) Scientist in API Particle Engineering, you will play a meaningful role in designing and engineering of crystalline particle attributes that enable robust, scalable, and manufacturable Active Pharmaceutical Ingredients (APIs). You will combine expertise in crystallization, isolation, drying, and particle characterization to expand particle engineering capabilities. Focus will be on evaluating different engineering and crystallization technologies as a basis for particle engineering technologies to be implemented in commercial processes. Based in Belgium , Beerse , you will join the Crystallization Technology Unit (CTU) —a recognized center of excellence supporting particle engineering and crystallization process development across the Johnson & Johnson synthetic molecule portfolio. This position is offered as a fixed term with a duration of 24 months. You will have the opportunity to work in a leading research team and innovation driven R&D campus. This experience will support your development towards next job opportunities.

In this role, you will research different particle tuning strategies for crystalline APIs, to develop new commercially viable technologies that deliver the desired API properties for successful manufacture of drug products. You will: Design and optimize particle engineering strategies to achieve target API characteristics such as particle size distribution, morphology, density, filtration performance, flowability, and solid-state form. Leverage crystallization fundamentals and engineering tools to research process control over particle attributes. Develop mechanistic understanding of particle formation and evolution through data-rich experimentation, process analytics, and scientific modeling. Evaluate the impact of process parameters on crystallization behavior, particle properties, manufacturability, and downstream process performance. Design scalable processes that consistently deliver desired API specifications from laboratory through commercial manufacturing. Apply advanced analytical techniques and PAT tools (e.g., UPLC, XRD, Raman, ATR-FTIR, laser diffraction, image analysis, DSC, DVS,...) to guide your research. Drive innovation in particle engineering through external collaborations, scientific networking, and engagement with academic partners.
