Check if values in a google sheet is mentioned on pages within

I need a wordpress developer who can write a code to check if values in a column on a google sheet doc is mentioned on pages within a specific directory (eg /jobs/). If you find a mention then show a text and icon at the top of the page.

This value (text and icon) should also be displayed on the jobs listing page (in addition to the detail view page mentioned above)

This field should also be included in the filters

This should be a cron job that runs every day 3am.
