We present a systematic framework for the calculation of dijet soft functions, which are defined as matrix element two light-like Wilson lines that is weighted by generic measurement function. Based on universal parametrisation phase-space integrals, we isolate singular terms in Laplace space and evaluate observable-dependent integrations numerically. discuss implementation our algorithm into public program SecDec, results various SCET-1 functions to two-loop order. In particular, obtain new predictions C-parameter angularity variables. Finally, ongoing extensions future outlook project.
