Crystallographer, Experienced Scientist R&d

Johnson & Johnson Johnson & Johnson · Pharma · Beerse, Antwerp, Belgium

This role focuses on crystallography and solid-state chemistry to characterize and control polymorphism of active pharmaceutical ingredients (APIs) for drug development. It involves applying expertise in X-ray, electron, or neutron diffraction techniques for structure determination and analysis, collaborating with cross-functional teams, and ensuring compliance with laboratory standards. The role requires a PhD in a related field and experience in solid-state materials science.

What you'd actually do

  1. Develop and optimize crystal growth
  2. Investigate transformation pathways and phase stability
  3. Perform structure determination using single-crystal and powder diffraction techniques (X-ray, electron, or neutron).
  4. Analyze and interpret crystallographic data to elucidate, refine, and validate structures.
  5. Support solid-state characterization, including polymorph identification, phase analysis, and crystal quality assessment.

Skills

Required
