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.
The EuXFEL "Strategy 2030+" identifies various development programs,
which are ongoing or about to start, aiming at short- to mid-term enhancements
to current capabilities and user experience. It also foresees programs,
with the purpose of developing or qualifying technology for a facility
upgrade during the next decade. This upgrade will bring advanced X‑ray
photon delivery modes, a higher number of pulses per second on sample
and attosecond X‑ray pulses, to name a few features. The data services
of the facility will need to evolve alongside to accommodate and prepare
for these developments. At the same time, efforts to improve the user
experience (UX) of some of these systems have started.

control system, Karabo, we are looking for a
