Do you update the job listings on a daily basis?
More often than daily. We import from python.org's job board, Remote OK and We Work Remotely every hour, and a listing submitted by an employer goes live as soon as it has been reviewed.
Listings expire 30 days after approval, and nothing stays on the home page longer than 60 days, so the front page is always recent openings — everything older is in the past jobs archive.
The one thing we cannot do automatically is notice that a role has been filled before its 30 days are up. If you posted it, close it from your job listings page. If you spotted it, use the flag link on the listing and we will take a look.
