How to check when a Lever job was posted
Lever records a created date for each posting, and the checker reads it as the original posting date.
Which dates Lever publishes
Lever's public API returns a created date as a timestamp. The checker converts it and shows it as "Originally posted" with an age.
That created date survives edits, which makes it a dependable anchor for how long a role has been listed.
The API also has an updated field in its schema, but it was absent from every live Lever posting we checked. The checker doesn't promise a "Last updated" date for Lever jobs.
If the job is closed or missing
Lever answers a missing company board and a missing job with the same 404. The checker can't separate the two, so it shows "Closed or no longer listed". If you get that result for a job you think is open, check the company name in the link for typos.
Lever doesn't supply a closing date either, so the checker can tell you a Lever job is gone but not when it closed.
How to spot a Lever job
Lever postings live at jobs.lever.co/{company}/{id}, where the id is a long string of letters, numbers and dashes. The application page adds /apply to the end of the same address.
The checker reads the posting with a single request to Lever's data and skips the application page.
Check a Lever link
Paste the company's apply link into the Job Age Checker. A Lever link with or without /apply at the end points to the same posting. LinkedIn and Indeed links are refused.
