You likely want add

After=aura-engine-lqs.socket

as well. See systemd manual on After=:

Note that those settings are independent of and orthogonal to the requirement dependencies as configured by Requires=, Wants=, Requisite=, or BindsTo=. It is a common pattern to include a unit name in both the After= and Wants= options, in which case the unit listed will be started before the unit that is configured with these options.

You porbably want to add RestartSec and configure the start limit as well
