Research Associate, fixed-term for 4 years

Research Associate (80% - 100%), fixed-term for 4 years Research Associate (80% - 100%), fixed-term for 4 years Laboratory Photonics, Time and Frequency | September 2026 or by arrangement The Federal Institute of Metrology METAS is the reference institute for measurements and measuring instruments in Switzerland. To ensure that a liter is always a liter (e.g., when refueling), METAS performs calibrations, conformity assessments, and consultations for industry, research, and administration. Measurement accuracy creates trust, especially on a social and political level, and is essential in many areas: in road traffic, electricity billing, time transfer, measurements in the environmental and health sectors, etc. At METAS, various specialist fields meet and complement each other – and this has been the case since 1862. Your tasks As part of the National Research Program 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, Uni Basel, and ETHZ. You will plan and implement a phase-stabilized fiber optic network for the distribution of reference frequencies between different research institutes in Switzerland. You will carry out preparatory work to metrologically establish the uncertainty budget of the Ca+-ion clock, and integrate it as a source of the optical reference frequency into the fiber optic network. A pilot study with the frequency reference FoCS2 and/or TAI will be conducted. As a member of the national research cluster PRECISION, you will participate in project meetings, workshops, and scientific conferences at national and international levels. You will generally contribute to the promotion of the activities of the Laboratory for Photonics, Time and Frequency. Your profile You have a Master's degree (University/ETH) possibly PhD/Doctorate in Physics or Physical Chemistry and have sound experience in one of the following areas: experimental quantum science, quantum optics, ion traps, time and frequency metrology, spectroscopy. Interest and knowledge in the concepts of metrology, especially in the field of time and frequency. Knowledge of RF and optical clocks, as well as time and frequency distribution networks, laser stabilization, and optics are an advantage. Strong communication skills and experience in acting as a central interface between project partners from different institutes and organizing the exchange efficiently. You enjoy working in a varied and demanding environment, show initiative, and enjoy activities at the interface between research and industry. Very good oral and written English skills We offer A varied activity at the interface between research and industry. METAS also offers attractive working conditions. You have the unique opportunity to participate in a flagship project within the framework of the National Research Program PRECISION. The Research Associate will take on a central role in the development of a state-of-the-art optical frequency standard (optical clock) as well as the associated frequency distribution network. This position offers the opportunity to work at the interface between the various project partners from science and industry.
