Only apply structured data to the most specific page describing a single job posting with its relevant details.
Put structured data on the most detailed leaf page possible.
Don't add structured data to pages that present a list of jobs (for example, search result pages).
Don’t add JobPosting markup on any other page, including pages that do not list any job.
