A proton has positive charge of 1, that is, equal but opposite to the charge of an electron. ... The charge is believed to be from the charge of the quarks that make up the nucleons (protons and neutrons).
Why does an electron have charge?
So now we can answer your question in the language of the quantum field: the electron gets its charge by the field allowing to create one positive charge state and one negative charge state at the same time, leaving its total charge zero.
