The date on a job board is not the date the job was posted.
Most boards show the date a listing was last pushed to them, not the date the employer opened the role. A requisition that is reposted every two weeks reads as two days old for months. A role that was filled in March stays up until it times out. Aggregators republish the same posting from one another, each with a fresh stamp.
JobShifu holds its own crawl history for every posting, so the card can state the observable facts instead: when this posting was first seen, whether the same requisition was listed before, and for how long it has been up.
Where the postings come from
-
Crawled from the employer's own system
Postings are read from the applicant tracking system tenant or the first-party careers site the employer actually uses, not from a board the employer syndicates to. That is the source of truth for whether a role is open, and it is where the application ends up regardless.

Measured 2026-08-22: every open posting in the index comes from an employer-direct source. The remote-job aggregator feeds that made up the last 2% were retired on 22 August 2026. Google's own listings are deliberately not crawled.
-
Indexed within minutes, not after the re-posts
The crawl runs continuously. The median gap between a posting appearing on the employer's page and appearing here is a couple of minutes; the slow tail is boards that only publish a sitemap once a day, and the strip at the top shows both numbers.
-
Taken down when the sweep finds it gone
Every board is re-swept. When a posting is no longer on the employer's page, it comes out of the index. Known re-posters, listings that reappear with a new stamp and no new requisition, are blocked at the source. The card never claims to know why an employer closed a role, only that the sweep can no longer find it.
