Not many jobs would happen at night. Because of light: if you wanted to see in the dark, you needed a lamp or a candle. Those light sources were dim by comparison with modern lighting. The cheap ones ( like tallow candles and rush lights) were smoky and stank like a grease fire ( since that's what they were, really) and non-smoky beeswax candles were very expensive- which is where the phrase "the game's not worth the candle" comes from: when the stakes in the card game are not worth the price of lighting the game. If you paid for space in a bed at an inn, you would normally have to pay extra for a candle. So, although it was not unheard of for a cobbler to be working late, in order to supply some repaired shoes the first thing in the morning, or a seamstress to be doing the same thing to a gown, or clerk to be checking items from the daybook and writing them in to the business' ledger, that was special duty: and not as cheap or easy as working in daylight.

There would be a kind of night shift for some occupations. If a pottery was firing a kiln, some brickmakers were firing a clamp of bricks, or a foundry was doing a big melt and had to bring a lot of brass up to temperature, it would take more than a day. Charcoal burning required long-term continuous management, also. But all that would be mostly a matter of managing a fire, which would tend to create its own illumination.

Poachers, robbers, prostitutes and burglars would be working at night. And there would be a night watch, men with lanterns patrolling the town and ( hopefully) deterring crime. But perhaps that's not quite what you had in mind by "night shift".
