Following the odyssey mentioned in https://lemmyrs.org/post/87787 and the discussion with users.rust-lang.org mods, I have concluded that the simplest and most sustainable way to solve this is a GitHub org where companies can post jobs and regular Rust developers on GitHub participate in moderation. GitHub provides different models of content structure and isn't restrained by what's possible in a Lemmy or Discourse thread.

To that end, I welcome anyone interested in moderating job posts to comment here for an invite to the org.
