PhD Student for Development of Strategies for GHz Speckle Experiments at European XFEL European XFEL GmbH in Germany

The European XFEL GmbH, located in the Hamburg metropolitan area, Germany, is seeking a PhD student (f/m/d) for the development of strategies for GHz speckle experiments. The European XFEL operates a world-leading 3.4 km-long X-ray laser facility, enabling cutting-edge research in physics, chemistry, life sciences, and materials science. The Data Analysis group and the MID scientific instrument are offering this position to advance X-ray Photon Correlation Spectroscopy (XPCS) into the GHz regime, leveraging recent technical advances at the facility.

The successful candidate will focus on developing methods and data analysis workflows for GHz speckle experiments, including the application of X-ray Speckle Visibility Spectroscopy (XSVS). The role involves simulating GHz speckle experiments to optimize methods and experimental parameters, as well as participating in relevant experimental activities. This research aims to establish GHz speckle techniques as a viable experimental approach for studying nanoscale and atomic-scale dynamics in various materials.

Applicants must have a Master's degree in physics (with a grade of 'good' or better), experience in scientific programming (Python, Julia), and a strong interest in experimental physics. English proficiency is required, as it is the working language. Additional experience with large datasets, photon science techniques (such as XPCS), simulation development, and participation in experiments at light sources (synchrotron or XFEL) is highly advantageous.

The position offers a vibrant international and multi-cultural work environment, flexible working times, family-friendly policies, 30 days of vacation, extensive relocation benefits, a generous company pension scheme (6.45% of monthly salary), monthly social events, a subsidized company restaurant, partially financed public transport tickets, subsidized English and German language classes, and free access to a mental health platform. The appointment is limited to 3 years and is part-time (29.25 hours/week).

Applications should be submitted online via the application portal. Required documents include a CV, motivation letter in English, and any reference letters. The European XFEL GmbH is an equal opportunity employer and supports diverse teams. Applicants with disabilities will be given preference if equally qualified. The application deadline is 6 May 2026.
