We conduct Bayesian inference of the $\\Lambda$CDM parameters $\\Omega_m$, $\\Omega_b$, $h$, $n_s$, and $\\sigma_8$ from the BOSS CMASS galaxy sample by combining the wavelet scattering transform (WST) with a simulation-based inference approach enabled by the ${\\rm S{\\scriptsize IM}BIG}$ forward model. We design a set of reduced WST statistics that leverage symmetries of redshift-space data.
