Hamilton studied law and language at Caius College, Cambridge before attracting attention as an oarsman with Thames Rowing Club. He was a member of the Thames eight which won the Grand Challenge Cup at Henley Royal Regatta in 1927.

Hamilton was an employee of the book department at Harrod's before founding his own publishing house Hamish Hamilton in the 1930s. He went on to publish a large number of promising British and American authors, many of whom were personal friends and acquaintances of Jamie Hamilton. Jamie Hamilton sold the firm to the Thomson Organisation in 1965, who resold it to Penguin Books in 1986,
