DESY, with more than 2900 employees at its two locations in Hamburg and Zeuthen, is one of the world’s leading research centres. Its research focuses on decoding the structure and function of matter, from the smallest particles of the universe to the building blocks of life. In this way, DESY contributes to solving the major questions and urgent challenges facing science, society and industry. With its ultramodern research infrastructure, its interdisciplinary research platforms and its international networks, DESY offers a highly attractive working environment in the fields of science, technology and administration as well as for the education of highly qualified young scientists.

DESY expands its research on novel laser-plasma accelerators (LPAs) for future applications in health, photon science and particle physics. At the core of these activities is the development of a plasma-based injector for the synchrotron light source PETRA IV. In this context, we are searching for a highly-motivated scientist to lead and shape our activities in data-driven design, optimization and real-time control of high-average-power LPAs.

With the PETRA IV project, DESY is launching one of the most ambitious and innovative large-scale research projects worldwide. PETRA IV, the most brilliant synchrotron radiation source of the next generation, will be the ultimate 4D X-ray microscope, setting new standards in precision and performance. To implement the project, we are looking for motivated employees who want to get involved in a complex project with international appeal.
