- a completed university degree in physics or biophysics
- experience in the field of time-resolved spectroscopy of triplet processes in the near-infrared (NIR) range
- experience with LabVIEW programming for lab system control
- ability to work independently
- very good knowledge of German or English (at least B2 level), demonstrated through a sample text and during the interview
