Stellenangebot: Wissenschaftliche Mitarbeiterin als Gruppenleitung für MIN (w/m/d) bei Dt Elektronen-Synchrotron DESY Personalabteilung

For our location in Hamburg we are seeking:

Postdoctoral researcher for X‑ray microscopy at atomic resolution

Limited: 2 years | Starting date: earliest possible | ID: FSPO009/2026 | Deadline: 20.10.2026 |

Full-time/Part-time

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.

The Advanced Multilayer X‑ray Optics group at CFEL is one of the leading research groups developing novel X‑ray lenses, also known as multilayer Laue lenses (MLLs). We plan to further improve and extend MLLs as part of a large project to image, understand and ultimately control electron dynamics in molecular systems. To do this, we are combining concepts from X-ray microscopy, crystallography, and ultrafast X‑ray science. Here is an opportunity for a highly motivated postdoctoral researcher to be part of our team and this exciting project.

About your role:

• Prepare and conduct scientific experiments at various X‑ray facilities (synchrotrons and XFELs)
• Develop and apply techniques to characterize and improve X‑ray lenses (MLLs) and gratings
• Extend and improve X‑ray imaging modalities towards atomic resolution
• Explore the feasibility of MLLs for various experiments and for their increased use at lab, synchrotron and XFEL sources
• Communicate findings via publications and presentations

About you:

• PhD in physics, applied physics or a related field
• Sound knowledge of Fourier optics, X-ray physics, and metrology
• Experience in experimental methods or development of instrumentation
• Experience with synchrotron and XFEL experiments is an advantage
• Good programming skills, especially in Python
• Proficient in English and in writing scientific articles
• Excellent interpersonal and communication skills
• High self-motivation and ability to work in an interdisciplinary team

Good reasons to join:
