If neutrinoless double beta decay is observed, it will be important to understand the mechanism(s) behind this process. Using a minimal supersymmetric extension to the standard model in association with a lepton number violating coupling as an example, we show that if neutrinoless double beta decay is mediated by new TeV scale particles, looking for four-jet final states in future linear colliders operating in the same-sign electron mode could provide important information on the underlying mechanisms. We study the prospects for observing this process at the proposed ILC and CLIC energies, and discuss the complementarity between such a four-jet signal and other collider signatures at the LHC.
