Hard probes are a very important tool to probe the hot and dense nuclear medium created in heavy-ion collisions at LHC energies. Heavy quarks are produced dominantly through hard partonic scattering processes in the earliest stage of the hadronic collisions and thus they probe all the stages of the system evolution. Jets enable to study hard scattering, fragmentation and hadronisation as well as the mechanism of in-medium partonic energy loss. The ALICE experiment is devoted to study the physics of nucleus-nucleus collisions, and particularly the physics of heavy quarks. High resolution tracking down to low transverse momentum, and good particle identification provide access to many hadronic and semileptonic decay channels of heavy-flavour hadrons, both at mid and at forward rapidity. The main results on heavy flavours and jet production in Pb-Pb collision at ALICE will be presented.
