Scope of workfull-time position suitable for part-time

Your responsibilities

Duties include academic services in the project named above. Research associates may also pursue independent research and further academic qualifications.

We are opening a postdoctoral position at the Center for Free-Electron Laser (CFEL) Science in Hamburg, jointly hosted by two leading research groups specializing in attosecond spectroscopy and FEL science. The CFEL-ATTO group has recently developed a cutting-edge light source capable of delivering few-femtosecond UV pulses, which have been used to capture light-driven electron dynamics that modulate the chirality of molecules [Wanie et al., Nature, 2024]. The position is part of the DFG-ANR project CACTUS, aiming at Capturing Attosecond-to-femtosecond Chiral Transients with Ultrafast Spectroscopy. The postdoctoral researcher will perform complementary experiments using both advanced table-top laser sources as well as world-class FEL facilities to investigate the electronic and structural dynamics of complex systems through charged particle detection. The work will include both optical and molecular source development. This unique opportunity offers the candidate access to cutting-edge technology and a collaborative environment aimed at pushing the frontiers of ultrafast science.

The tasks include:

• preparation and implementation of laser-based studies on ultrafast processes in chiral matter
• experiments on nonlinear light-matter interaction with laser and X-rays
• further experiments on X-ray light sources, e.g. storage ring systems and free-electron lasers
• operation and development of measuring equipment in the laboratory
• laboratory activities, e.g. set-up, commissioning and maintaining instrumentation
• determination of scientific data through e.g. literature research, experiments, questionnaires, models
• analysis and interpretation of scientific data
• writing of publications, participation in conferences
• supervision of doctoral candidates and students
• investigation and preparing reports
• committee work
• organization of workshops and conferences
• instruction of, discussion with and knowledge transfer to other support groups

Your profile

A university degree in a relevant field, plus doctorate.

• very good experience in the field of laser technology and spectroscopy
• strong background in laser-based spectroscopy, including experience with ultrafast femtosecond light sources
• experience with ultra-high vacuum technologies and charged particle detectors (ions/electrons)
• very good experience with data analysis, ideally with Python as the programming language
• project management experience
• the candidate must have publications as first author
• UHV experiences and experiences in electron/ion detector
• strong organizational and teamwork skills to thrive in a collaborative, interdisciplinary environment
• excellent communication in English is necessary; knowledge of German is a plus
• experimental skills and interest in instrumentation development, with a track record of scientific publications
• experience with molecular clusters sources is highly desirable
• very good experience in preparing scientific papers

We offer

• Reliable remuneration based on wage agreements
• Continuing education opportunities
• University pensions
• Attractive location
• Flexible working hours
• Work-life balance opportunities
• Health management, EGYM Wellpass
• Educational leave
• 30 days of vacation per annum
