Gois initially studied under Étienne Jeaurat, then went into the workshop of Michelangelo Slodtz.
He won the first grand prize for sculpture in 1757, on a bas-relief with the subject Tullie faisant enlever les morts.
At the end of his stay at Palazzo Mancini, he executed a bust of la Douleur (Pain), a work that was presented three years later at the Paris Salon to great success.
He was then appointed Professor on 7 July 1781, replacing Louis-Jean-François Lagrenée (the Elder).
In 1788 he gave the academy a model he carefully executed of a flayed horse.
