HN itself is the biggest bottleneck, IMO. A few days after the thread has been posted, it gets paginated, usually into 3 or 4 pages. Assuming you Cmd+F/Ctrl-F for a couple keywords (remote, state, city), you end up having to do 10+ searches, in addition to weeding out the "no remote" matches. On the same note, it's very hard to keep track of new posts after the first day or two, which means you're searching for "minutes ago" "hours ago" "1 day ago" "2 days ago" etc - again, on 3 or 4 pages.

I know there's one user who maintains a site that lists all of the job postings (forgot the url), but personally I'm not a huge fan of the layout.
