Optical driving of materials has emerged as a versatile tool to control theirproperties, with photo-induced superconductivity being among the mostfascinating examples. In this work, we show that light or lattice vibrationscoupled to an electronic interband transition naturally give rise toelectron-electron attraction that may be enhanced when the underlying boson isdriven into a non-thermal state. We find this phenomenon to be resonantlyamplified when tuning the boson's frequency close to the energy differencebetween the two electronic bands. This result offers a simple microscopicmechanism for photo-induced superconductivity and provides a recipe fordesigning new platforms in which light-induced superconductivity can berealized. We propose a concrete setup consisting of a graphene-hBN-SrTiO$_3$heterostructure, for which we estimate a superconducting $T_{\rm c}$ that maybe achieved upon driving the system.
