Advertise in the Startd's ClassAd the existence (or otherwise of the
file) something like

HasTheFlibbleFile = True
HasTheFlibbleFile = False

Then in your job submission file include in the requirementes

HasTheFlibbleFile == True

Obviously this is not automated, if you prefer that you can look at
things like Hawkeye to automate the setting of the attribute but the
basic principle remains the same...
