A search for heavy Majorana neutrinos in events containing a pair ofhigh-$p_{\mathrm{T}}$ leptons of the same charge and high-$p_{\mathrm{T}}$ jetsis presented. The search uses $20.3 \mathrm{fb}^{-1}$ of $pp$ collision datacollected with the ATLAS detector at the CERN Large Hadron Collider with acentre-of-mass energy of $\sqrt{s} = 8$ TeV. The data are found to beconsistent with the background-only hypothesis based on the Standard Modelexpectation. In the context of a Type-I seesaw mechanism, limits are set on theproduction cross-section times branching ratio for production of heavy Majorananeutrinos in the mass range between 100 and 500 GeV. The limits aresubsequently interpreted as limits on the mixing between the heavy Majorananeutrinos and the Standard Model neutrinos. In the context of a left-rightsymmetric model, limits on the production cross-section times branching ratioare set with respect to the masses of heavy Majorana neutrinos and heavy gaugebosons $W_{\mathrm{R}}$ and $Z'$.
