The heavy-ion program at ALICE is aimed at studying strongly interacting matter in ultra-relativistic nuclear collisions where the formation of a quark-gluon plasma (QGP) is expected. Jets can be used to probe the QGP. Earlier studies at the LHC have shown that jet production is suppressed in heavy-ion collisions. This suppression is attributed to elastic and/or radiative interactions between the parton and the QCD medium, which transport jet momentum outside the jet cone. The dependence of the energy loss on the in-medium path length provides insight into the energy loss mechanisms. This path-length dependence can be studied by measuring the jet yield with respect to the event plane. This contribution will show results of measurements of charged jet yields in central $\sqrt{s_{\rm NN}} = 2.76 $ TeV Pb-Pb collisions with respect to the second order event plane. Jet finding is performed with the anti-k$_{\rm{T}}$ algorithm with a resolution parameter $R$ = 0.2, using charged tracks from the ALICE central tracking system. The contribution of hydrodynamic flow to the underlying event is taken into account on an event-by-event basis.
