Join the Neutrino Platform Project to contribute to the DUNE experiment, an International Collaboration, at the frontier of the research in Neutrino physics. We're looking for a Detector Physicist in High Energy Physics and specific knowledge and expertise in Liquid Argon (LAr) Time Projection Chamber (TPC) detectors to support the activities and the commitments of the scientists and engineers in the CERN Neutrino Platform for the DUNE Vertical Drift Far Detector. Your responsibilities: - Test and characterisation of Charge Readout Planes for the DUNE Vertical Drift Far Detector. - Prepare Technical Specifications and tendering for the manufacture and assembly of large printed circuit boards that will form the anode panels collecting the signals from the LAr TPCs detectors. - Support the follow-up of contracts with industrial partners in the production and the assembly of the LAr TPC electrodes. - Analyse and assess the quality of the productions of the detector components. - Participate to the test and validation of the detector systems. This role includes team supervision responsibilities. Your profile: - Manufacturing and assembly of large printed circuit boards for the readout electrodes of Time Projection chambers based on noble liquids. - QA/QC validation of detector components. - Testing of small and large scale cryogenics detectors - Readout and Data Acquisition systems. Skills: - Knowledge of signal formation and process in noble liquid-based detector. - Expertise in software development in C++ and Python for the analysis of the data. - Expertise in developing program of data acquisition systems to control and monitor real-time detector performance. - Excellent communication skills, flexibility and adaptability to work in large international collaborations. - Spoken and written English or French, with a commitment to learn the basics of the other language. Eligibility criteria: - You are a national of a CERN Member or Associate Member State. - You have a professional background in PhD in High Energy Physics (or a related field) and have either: - a Master's degree with 2 to 6 years of post-graduation professional experience; - or a PhD with no more than 3 years of post-graduation professional experience. - You have never had a CERN fellow or graduate contract before.

About us At CERN, the European Organization for Nuclear Research, physicists and engineers are probing the fundamental structure of the universe. Using the world's largest and most complex scientific instruments, they study the basic constituents of matter - fundamental particles that are made to collide together at close to the speed of light. The process gives physicists clues about how particles interact, and provides insights into the fundamental laws of nature. Find out more on http://home.cern. We are on a Quest.
