We present an extension of hybrid approach, which combines viscous hydrodynamics, particlization, jet energy loss and hadronic cascade, to describe data in the intermediate and high $p_T$ regimes. This enables us to study mini-jet production and energy loss in heavy ion collisions, in conjunction with the bulk dynamics of QGP fireball. This hybrid approach is applied for Pb-Pb collisions at the LHC with $\sqrt{s_{NN}} = 2.76\,\textrm{TeV}$, and we demonstrate that hadronic re-scatterings have significant effects on mini-jets with intermediate $p_T$.
