LAPP proposes a position for an analog electronics engineer in order to participate in the Virgo experiment upgrade, Advanced Virgo+. Virgo is a gravitational wave detector, located in Pisa Italy. The engineer will join the LAPP's Virgo team, made of physicists and engineers, and will participate in the analog electronics developments that will be essential for the future detector's performances. The work will be principally the study and the fine tuning of pre-amplification systems for the several detection photodiodes channels. The engineer will participate in the on-site commissioning. More generally, He will study new projects, as for instance a new current generator for the calibration LEDs. The engineer will join the electronics department and will be assisted by a senior engineer.

LAPP is a physics laboratory located in Annecy, 50kms from Geneva and CERN. The laboratory was founded in 1976 and is one of the 20 laboratories of IN2P3 (Institut de Physique Nucléaire et de Physique des Particules), institute of CNRS (Centre National de la Recherche Scientifique). LAPP is joint research facility of the University Savoie Mont Blanc (USMB) and the CNRS. Nearly 150 people are working at LAPP: researchers, professors, support staff, students and visiting scientists. Research carried out at LAPP aims at understanding the elementary particles and the fundamental interactions between them as well as exploring the connections between the infinitesimally small and the unbelievably big.
Virgo is an international experiment dedicated to gravitational wave detection. It is located in Pisa, Italy. Virgo is a giant Michelson interferometer, 3km long. The LAPP group is responsible of the photo-detection electronics systems, of the signals shaping and acquisition, and of many electronics interfaces in the detector (timing, data switching, control signals…). The LAPP Virgo team includes 9 physicists, 12 engineers and 7 Phds. The electronics department includes 16 people; their mission is to develop electronics systems for particle physics experiments.
