Run-II of the LHC is probing the Standard Model of particle physics at unprecedented energies and precision. At such large energy scales higher-order electroweak (EW) corrections are strongly enhanced due to the presence of large Sudakov logarithms. Their inclusion in the experimental analyses will significantly enhance the sensitivity for new phenomena. In my talk I will present a fully automated implementation of next-to-leading order (NLO) EW corrections in the OpenLoops matrix-element generator combined with the Sherpa and Munich Monte Carlo frameworks. As an application, I will present NLO QCD+EW predictions for vector boson production in association with up to three jets. In my talk I will compare predictions in the on-shell approximation against fully off-shell computations. Furthermore, I will present an approximate multi-jet merging and parton-shower matching including electroweak corrections.
