This document outlines a converged science program between the LHCb experiment at CERN and the Square Kilometre Array Observatory (SKAO), focusing on the search for Dark Matter. It details how both facilities face similar extreme data processing challenges due to the unprecedented volume of data generated, requiring real-time processing and efficient data management. The paper highlights the potential for knowledge and methodological transfer between the two distinct scientific communities, proposing the sharing of simulated data samples and the development of modular, interoperable software components to maximize their scientific output and efficiently address the persistent mystery of Dark Matter.
