The Deep Underground Neutrino Experiment (DUNE) aims to unlock the mystery of neutrinos. One of the major goals is to measure the CP-violating phase of the neutrino mixing matrix for which the DUNE near detector (ND) is crucial. A leading role in measuring neutrino interactions in the ND will be filled by the high-pressure gaseous argon TPC. A sampling ECAL based on plastic scintillators with SiPM readout is surrounding the TPC (ND-GAr). In this talk, optimized geometries are considered for the ND ECAL motivated by external boundary conditions and the beam-on-target nature of DUNE. A second focus will be on the readout of the ECAL's scintillator strips trying to efficiently use the available space and optimizing the light output.
