The LHCb experiment at the LHC proton-proton collider at CERN is dedicated to studies of heavy flavour physics, with the major goal of testing the Standard Model of particle physics and finding any potential deviations due to New Physics in decays of heavy hadrons. After a major upgrade, LHCb is restarting data taking in 2022. Over the next few years, it will collect unprecedented data samples bringing the measurements to a new level of precision.

The Experimental High Energy Physics group at the Universitat de Barcelona has an extensive experience in data analysis involving rare decays and has participated since the inception of the detector in calorimetry R&D.

The successful candidate is expected to take an active role in LHCb data analysis in regarding hints for lepton flavour non-universality either in electroweak penguin decays or in semileptonic decays, as well as in the R&D carried out by the group for the Upgrade 2 calorimeter, including the participation in test beams.

Applicants must have a PhD in experimental particle physics or in a related field with relevant experience. A very good knowledge of software development and modern programming languages (e.g. C++, Python) are necessary, experience with
