Beamline Scientist Manager – Lead Ultrafast TEMPO Research in Saint-Aubin

Located on the Paris-Saclay plateau, about 20 kilometers from the capital, the SOLEIL synchrotron is one of France’s leading research facilities. Since it began operating in 2008, it has served the national and international scientific communities. Research conducted at SOLEIL covers a wide range of scientific and industrial fields — including physics, biology, chemistry, materials science, environmental science, Earth sciences, and cultural and natural heritage — all connected to current societal challenges. Experiments carried out on the beamlines rely on the use of synchrotron light emitted by electrons accelerated to nearly the speed of light within a storage ring. SOLEIL is jointly supervised by the CNRS and the CEA and offers its staff a dynamic, innovative, multidisciplinary, and international working environment.
At the forefront of technology, SOLEIL II is an ambitious project designed to provide new opportunities for scientific and industrial research. SOLEIL II consists of a major upgrade of the existing infrastructure and aims to significantly improve the performance of electron accelerators and beamlines. It is designed to address major current and future societal challenges, particularly in areas such as advanced materials research, energy and sustainable development, health and well-being, and the environment.
Construction work on the SOLEIL II project began in 2024, marking the start of a phase of development and technological innovation. In parallel, the existing facility will remain operational until May 2029. SOLEIL II is scheduled to start operations in 2030, with a gradual ramp-up phase continuing until 2035.

I.Context and mission
The TEMPO Beamline (Time-resolved Experiments on Materials with PhOtoelectron spectroscopy), https://www.synchrotron-soleil.fr/en/beamlines/tempo

The TEMPO beamline is dedicated to the study of the electronic properties of surfaces and interfaces using photoemission and photoabsorption spectroscopy in the soft X-ray range. It is unique in Europe in its ability to investigate ultrafast dynamics using time-resolved photoemission, while also offering the possibility of performing photoemission experiments under controlled gas pressures close to ambient pressure. More recently, the feasibility of performing angle-resolved photoemission spectroscopy under near-ambient-pressure conditions was demonstrated for the first time worldwide on the beamline.

The TEMPO beamline has been open to users since 2007. It comprises two main branches: a first branch dedicated to photoemission under ultra-high vacuum (UHV) conditions, and a second branch for photoemission experiments under controlled gas pressure. Both branches are equipped with experimental stations providing an ideal environment for the preparation and characterization of surfaces and interfaces in complex systems. The TEMPO beamline enables detailed, high-quality studies in a wide range of scientific fields involving metallic as well as organic and inorganic semiconductor systems. The beamline is optimized for the study of chemical kinetics and relaxation dynamics of phenomena induced by electrical and optical excitation. It also enables measurements of Position : Beamline manager (Tempo) Mise à jour : 10/09/26

IV.Working conditions
This is a fixed-term contract. The position is based in Saint-Aubin (Essonne), at the SOLEIL Synchrotron.
If you are looking for a position in a company built on the pillars of scientific excellence and technological innovation, SOLEIL offers you the opportunity to:
•
Work within an innovative, multidisciplinary, and multicultural research laboratory.
•
Be at the heart of the research and development dynamics of the Paris-Saclay cluster.
•
Collaborate with national and international experts across diverse scientific and technical fields.
•
Take advantage of Paris being only 25 km away, offering rich cultural experiences and a vibrant lifestyle.
•
Undertake short trips within France or Europe. Benefits :
•
