Appointed Founders of the Royal Brass Foundry at Woolwich in 1784, and Foreman and Assistant Foreman in 1789 being promoted to Master Founder and Assistant Founder on the revival of these offices in 1797. John King continued in the post until his death in 1813 when he was succeeded by his brother Henry (W.O.47/116, p. 692; W.O. 47/2560, p.414; W.O. 47/2630, p.1143), until his retirement in 1818, when the post of Master Founder was abolished.

On the retirement of his uncle, Henry King, he remained in charge of the foundry with the rank of Acting Founder. He retired in 1822 to be succeeded by William North.
