Join our team

European XFEL is an international non-profit company located in the Hamburg area in Germany. It operates a 3.4 km-long X-ray laser, which produces X-rays of unique quality for studies in physics, chemistry, the life sciences, materials research and other disciplines. The diverse scientific facilities at European XFEL enable scientists from across the globe to carry out a wide range of experimental techniques.

For our FXE group we are looking for a:

Postdoc Scientist for development of High-Energy Laue X-ray spectrometer (f/m/d)

The position

The successful candidate will work closely with the instrument scientists and technical staff at FXE, as well as with our international collaborators to develop, install and commission a novel X-ray emission spectrometer for high photon energies (≳ 15 keV) to be utilized in ultrafast time-resolved experiments at the FXE Scientific Instrument. Specific tasks include:

  • Perform ray tracing studies to investigate and optimize the chosen spectrometer geometry
  • Develop and characterize a new analyzer bender to improve the spectrometer efficiency
  • Develop, implement, maintain and operate the new spectrometer at the FXE instrument, including the MHz framerate hybrid pixel detector, maintaining compatibility with existing setups of the instrument
  • Actively support the operation, maintenance and development of all X-ray spectroscopy instrumentation at FXE, while also contributing to relevant scientific activities within the group


  • PhD degree in physics, chemistry or equivalent
  • Extensive experience with X-ray spectroscopies is required. Acquaintance with ultrafast pump-probe X-ray techniques is an additional asset
  • Knowledge of ray tracing X-ray simulations and X-ray optics is required
  • High motivation for independent research involving instrumentation and methodology development, but also new applications in the field of structural dynamics of soft and hard condensed matter systems
  • Acquaintance with femtosecond optical lasers, novel X-ray detectors, and analysis of large data sets are additional assets
  • Experience in advanced data analysis and programming skills (Matlab and/or Python, or similar) is an asset
  • Excellent communication skills and the ability to work in a multi-lingual, multi-disciplinary team, with English as the working language.
