1. Start by personally introducing the new hire to all team members. This helps them feel comfortable approaching them later on to ask questions. 2. Ask them to write a "how to set up a new dev env" wiki page. The next new hire can improve it. 3. Give them a handful of medium priority bugs to fix. Not critical as its too early, and not trivial as that won't drive learning. A nice mix of bugs should take your newbie to all major parts of the system, and require them to develop understanding in a way that new code often doesn't. The bugs should also drive conversations with the original authors of the code that will help knowledge transfer.
