How to manage Expired Job Removal

Hi All,

I have one job board where I am posting jobs regularly which defiantly has some expiry and I would like to know some practical example to manage the removal of the jobs upon expiry. I have read Google Job Posting Guideline but still confused about returning 404 to the user when the job is expired and due to this I am getting manual action as follows,




Would be great if anyone can guide me to manage expired job posting
