A "mechanical Turk", as amazon would call it, a "Code Monkey" as Jonathan Coulton sang in his song.
A completely exchangeable person, an employee as a service. How the code is written, who does it, is entirely irrelevant. Entirely replaceable, with no recourse for the "contractor".
The main component of the gig economy is exactly this, completely disenfranchising the worker by commoditizing work. You try to negotiate higher pay, you simply get replaced.
