Enlightening Science

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.

We are seeking a motivated researcher to work on a European-wide optics and metrology project. You will play a central part in coordinating tasks with a systematic study of contamination of X-ray optics, applying various cleanroom technologies to recover them to their original state.
