Scientific Collaborator 4-year fixed-term position

Scientific Collaborator (80 %-100 %) 4-year fixed-term position Scientific Collaborator (80 %–100 %) 4-year fixed-term position Photonics, time and frequency laboratory | for 1 September 2026 or a date to be agreed METAS – or Federal Institute of Metrology – is the reference institute in Switzerland for measurements and measuring instruments. To ensure that one litre is always one litre (for example, when you fill up your tank), METAS performs calibrations, conformity assessments, and provides advice to the economy, research, and administration. A source of trust, particularly on social and political levels, metrological accuracy is indispensable in many fields: road traffic, electricity billing, dissemination of time, measurements for the environment and health, etc. In other words, at METAS, disciplines have been side by side and in dialogue since 1862. Your tasks As part of the national research center PRECISION, you will play a central role in the development and characterization of an optical frequency standard based on trapped Ca+ ions, in collaboration with PSI, the University of Basel and ETHZ. You will plan and implement a phase-stabilized optical fiber network intended for the distribution of reference frequencies between different research institutes in Switzerland. You will perform preparatory work to establish, from a metrological point of view, the uncertainty budget of the Ca+ ion clock, and then integrate it into the optical fiber network as an optical reference frequency source. A preliminary study is being conducted with the FoCS2 and/or TAI frequency reference. As a collaborator of the national research center PRECISION, you will participate in project meetings, workshops, and scientific conferences at national and international levels. You will contribute in a general way to the promotion of the activities of the Photonics, time and frequency laboratory. Your profile Master's degree from a university or EPF evtl. doctorate (PhD) in physics or physical chemistry and you have solid experience in one or the other of the following fields: experimental quantum science, quantum optics, ion traps, time and frequency metrology, spectroscopy. You are interested in metrology concepts and have corresponding knowledge, particularly regarding time and frequency. Knowledge of RF and optical clocks, as well as time and frequency distribution networks, laser stabilization, and optics is an asset. Excellent communication skills, ability to serve as an interface function between project partners from different institutes. Enjoying working in a varied and demanding environment, you demonstrate autonomy and enjoy activities at the interface between research and industry. You have very good oral and written skills in English. We offer you A varied activity at the interface between research and industry. METAS also offers attractive working conditions. You have a unique opportunity to contribute to a flagship project within the framework of the national research center PRECISION. The candidate will play a central role in the development of a cutting-edge optical frequency standard (optical clock) as well as the associated frequency distribution network. This position offers the possibility to work at the interface between the different project partners, both academic and industrial.
