It's being the tech lead of a team of junior to mid level developers. You design roughly what the solution should look like, split it into reasonable sized tasks so they don't go off the deep end, advise them on some of the details, then assign them the tasks and let them get on with it, keeping an eye on what they're doing, reviewing their output, and course correcting them when they go wrong.

Just like with a team of humans, you have to use your judgement as to how much supervision they need individually and how large a task you can give them without them going off the rails.
