The search for neutrinoless double beta decay (NDBD) provides the most sensitive experimental test of lepton number conservation, as well as a powerful experimental probe of the nature and mass scale of the neutrino. In this talk, I will introduce the nEXO experiment: a proposed next-generation search for the neutrinoless double beta decay of $^{136}$Xe with a halflife sensitivity of ~$10^{28}$ years, two orders of magnitude beyond existing experiments. Building on techniques developed for the successful EXO-200 experiment, the primary detector will be a five-tonne, monolithic liquid xenon time projection chamber (TPC) with a source enriched to 90% in $^{136}$Xe. We will discuss the science goals of nEXO, then describe how the experiment addresses the stringent low-background requirements of next-generation NDBD searches using a combination of conservative design choices (driven by EXO-200 experience) and novel readout schemes designed to improve the energy resolution and background rejection capabilities of the detector.
