When leading/mentoring junior engineers, it's important to check in periodically and ask questions so that you know that they understand what they're working on and that they're not stuck. You can't expect them to raise those issues themselves. That's one of the things that makes them juniors. So yeah, you've got to spend some time every day syncing up with them and making sure things are on track. That's true if they're remote or in the office, but if they're remote, managers need to be a bit more proactive in asking questions and following progress.
