You can schedule a job through cron - which will have the line
find /tmp/staff_info -mtime +7 | xargs rm

Using xargs will help in not triggering too many rm commands simultaneously causing system to be loaded during that period.

The normal method would have been
find /tmp/staff_info -mtime +7 -exec rm {} \;
But I prefer the 1st method.

A minor point: It is considered bad form to use /tmp for user temporary files; /tmp is for system-related temporary files. Instead, you should use /var/tmp/staff_info. Even better is to observer the TMPDIR convention which says if TMPDIR is defined use that value otherwise default to /var/tmp.

The correct method is:
find /tmp/staff_info -mtime +7 -exec rm {} +

This calls rm with as many args as will fit.
