Maybe I'm overthinking it, but wouldn't NIP1 for a job post be indistinguishable from non-job posts (gotta filter out the "GM"s)?

Right, but would that be a bad thing? That way regular Nostr clients would also display the job listings. For the LN-like client to only display the job listings you'd need to use a hashtag. Just like Swarmstr only shows notes with the hashtag # asknostr.
But that's just an MVP. Something that's good enough to start.
