Join the 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. Experiment operation started in September 2017. The Theory group is focused on development and application of novel theoretical approaches and tools to support and advance research at the European XFEL. The group develops theory and software, as well as performs simulations to facilitate spectroscopic and scattering x-ray studies at FELs.
The Theory group is currently looking for a

Theoretical physicist for studies of the electronic structure of matter (f/m/d)

The Position
The successful candidate will contribute to further developments of the theory of interaction between FEL radiation and matter, with applications to experimental cases of interest for one or more instruments at the European XFEL.  He/She will work in close cooperation with scientists at the European XFEL and with large international collaborations. A non-exhaustive list of possible scientific subjects of interest follows:

  • DFT/GW calculations electronic structure of solids and theoretical investigation of X-ray Absorption Spectrum (XAS), X-ray Emission Spectrum (XES), Resonant Inelastic X-ray Scattering (RIXS) and ARPES-Spectrum
  • Modeling of time-dependent electronic spectrum of solids as a function of FEL pulses
  • Investigation of charge and spin dynamics under ultra-strong and ultra-fast FEL pulse Control of non-equilibrium quantum matter with specially shaped FEL pulses
  • Analyses of strong Light-Matter interaction in different XFEL experiments nDevelopment of theoretical tools for X-ray spectroscopy of correlated materials


  • Bachelor, Master or PhD in Computer Science or similar technical field of study (e.g. Engineering, Physics or Mathematics)
  • Proficient knowledge in Python and Object-Oriented Programming
  • Deep understanding of web technologies such as Javascript, HTML5 and CSS3 nExperience with C++ is considered an asset
  • Knowledge of the CONDA packaging system is an asset
  • Familiarity with Git and Gitlab CI is an asset
  • Experience in using a python based web framework (django, flask, tornado, …) is an asset
  • Experience with the deployment system Ansible is an asset
  • English is the working language, knowledge of German is considered an asset.
