But there is already a command to do that: fg. You can hook SIGCHLD
with a trap handler, process the `jobs' output, and fg the appropriate
process. I still think that's way more work than you need to do.

Since you're not really using job control at all, but controlling the
process's status by sending it signals from another process, you
could add a process in between, making the job you're interested in
a grandchild of the shell. That way it doesn't matter what the shell
does when it exits.
