  Hard-scattered partons provide an ideal probe for the study of the
Quark-Gluon Plasma because they are produced prior to the formation of the QCD
medium in heavy-ion collisions. Jet production is therefore susceptible to
modifications induced by the presence of the medium ("jet quenching"). Both
RHIC and LHC experiments have provided compelling evidence of jet quenching.
Jets are reconstructed in ALICE utilizing the central tracking system for the
charged constituents and the Electromagnetic Calorimeter for the neutral
constituents. Jet spectra are reported for central (0-10%) and semi-central
(10-30%) Pb-Pb events at $\sqrt{s_{\rm NN}}=2.76$ TeV. The nuclear modification
factor, determined using a pp baseline measured at the same collisional energy,
shows a strong suppression of jet production in central Pb-Pb collisions with
the expected centrality ordering. Observations are in qualitative agreement
with medium-induced energy loss models. Furthermore, indication of a
path-length dependence of jet suppression is inferred from measurements of the
yields relative to the orientation of the event plane.
