He was employed by the prominent English manufacturer and business man, Matthew Boulton to improve Boulton's coin and medal quality. However, he worked there for just two years. In 1789, Droz devised a collar used to engrave the sides of coins and ensure a circular shape, and though it was unsuitable for large numbers of coins, it remained in use at the Soho Mint.
He was a member of the Royal Birmingham Society of Artists.
