High-velocity molecular jets have been observed from several protostars in the early Class\\,0 phase of star formation, detected with the high-density tracer SiO. Until now, no clear jet has been detected with SiO emission from isolated evolved Class\\,I protostellar systems. We report a prominent dense SiO jet from a Class\\,I source G205S3 (HOPS\\,315: T$_{bol}$ $\\sim$ 180 K, spectral index $\\sim$ 0.417), with a moderately high mass-loss rate ($\\sim$ 0.59 $\\times$ 10$^{-6}$ M$_\\odot$ yr$^{-1}$) estimated from CO emission.
