Having been an introverted engineer you probably already know how much of a blessing you're going to be to other engineers who just want to be left alone to do their work. Only suggestion I would make (since I imagine that you, as an introvert, will already be pretty hands-off) is to occasionally ask yourself if what you're doing is making life easier for your engineers. Do they have roadblocks that you're able to remove? If removing that roadblock means a quick email, do it now and your engineers will appreciate you for it. Remember that your job is to manage and not to be a boss and you'll do just fine.
One quick addendum: if you're able to let your engineers work the way they way that they work best (i.e., remote, flexible hours, etc.), do it.
