A Research Associate (postdoctoral researcher) position is currently open in the DESY Attosecond Science Group within the Center for Free Electron Laser Science (CFEL) in Hamburg. The position focuses on developing a novel chiroptical platform for studying molecular recognition dynamics in the gas phase and is funded under the ERC grant KEBAB led by Dr. Vincent Wanie. The initial contract lasts 2 years with a possibility of extension.

About your role

Design and implement laser-based studies of ultrafast processes in chiral matter, emphasizing chiroptical observables
Develop few-femtosecond light sources, including a high‑repetition‑rate VUV (<200 nm) source with variable polarisation
Operate, commission, and maintain advanced experimental instrumentation, including ultrafast laser systems and vacuum‑based detection setups
Integrate novel measurement techniques, including charged‑particle detection schemes for photoelectron circular dichroism (PECD)
Acquire, process, and analyze experimental data, supported by numerical modeling and literature‑driven contextualisation
Prepare scientific publications and technical reports
Actively participate in international conferences and workshops, presenting research results
Execute experimental campaigns at large‑scale facilities (e.g., synchrotrons and free‑electron lasers), including on‑site coordination
Contribute to the strategic development of the ERC project, identifying new experimental directions and collaborations
Engage with international collaborators, coordinating joint experimental campaigns and integrating complementary theoretical and experimental approaches

About you

PhD in physics or a closely related field
Ability to independently design and implement experimental approaches while working effectively within an interdisciplinary team
Hands‑on experience with one or more of the following: hollow‑core fibers, optical parametric amplifiers, high‑power femtosecond laser systems
Experience with ultra‑high vacuum technologies, molecular sources, and charged‑particle detection (electrons/ions)
Background in molecular spectroscopy and experience in the analysis of electron and/or ion data
Excellent track record of scientific publications, demonstrating strong scientific writing skills
Excellent knowledge of English
