The very basic way:
Put your mount command into a script and just run that script via cron on startup. I will not elaborate on how to use cron because there are gazillion guides on google and I'm not a Linux expert anyway. Making that script literally just entails opening a text-editor, putting #!/bin/bash at the top, and put your mount command on the second line - so all you need is for cron to trigger it for you on startup.
The proper way:
Set the mount up as a system service. This has some added benefits. You can pretty much go steal Animosity's template for this as he shares all his Linux scripts - then just make some minor edits in the flags to meet your need:
Hopefully that gets you on the right track
