Despite significant strides made towards understanding accretion, outflow, and emission processes in the Galactic Center supermassive black hole Sagittarius A*, the presence of jets is still unproven. We investigate how jets may manifest themselves via frequency-dependent size scales and variability, as well as their spectral and morphological properties in the radio through infrared bands. In particular we present predictions of the size-versus-frequency scaling, flare evolution and lags between the IR and radio bands, and predictions for the jet appearance at 43 GHz after accounting for scattering. We compare these predictions to the current state-of-the art data and discuss future prospects for further constraining jet physics and geometry. So far our results favor a system of weak, bipolar jets that are highly inclined to the line of sight (θ ≥ 75°), with compact bases on the order of a few gravitational radii, and that lie on a position angle 105 degrees, east of north.
