Narrative:

We landed; and on rollout through 80 knots we got an ECAM hydraulic green low level. The hydraulics system page was displayed and showed low fluid quantity but still normal pressure. I was pilot flying and transferred control to the captain. ATC cleared us to hold while [waiting for] our gate [to] open. The captain told me to accomplish the ECAM procedure which included turning off the power transfer unit and the green system pump. At this point we lost steering and reported to ATC that we were a disabled aircraft with no steering and a hydraulic system failure. We set the parking brake and contacted company to get towed in. An airport vehicle approached us; established communications and reported fluid leaking from our nose gear. We ran the tow-in checklist and got towed in to [the] gate.
