We present a nano-optomechanical transducer using high stress silicon nitride that features a one-dimensional optical cavity (Q>10^5) integrated with a high aspect ratio nanobeam resonator(Q>10^6). Our approach allows individual optimization of the optical and the mechanical resonator while maintaining a high optomechanical coupling rate. This system provides a platform for observation of room temperature quantum backaction on macroscopic mechanical resonators owing to its high single photon cooperativity (C0 = 23).
