Before becoming involved with his grandfather's company, Occidental Petroleum, Hammer served in different roles at the New York City securities and investment banking firm Kidder, Peabody & Co.,[8] which later was sold to PaineWebber, which ultimately merged with UBS AG in November 2000. He joined Occidental Petroleum in 1982 and served in various capacities in the company's facilities in Texas, Oklahoma, London, and Oman. In 1985, he moved to the corporation's headquarters in Los Angeles where he became a vice president, He shortly thereafter became a member of the board of directors and the executive committee, and served in those capacities until his departure from the company in 1991, not long after the death of Armand Hammer.

Since leaving Occidental, Hammer has worked with several companies, including OnVANTAGE, Inc. in 2000,[9] which was later acquired by the company StarCite, Inc., and Avenue Entertainment Group as a member of the Board following an investment in the company by Hammer International in 1999.[8]

Hammer formerly resided in a Paul Williams-designed, 1920s Tudor-style mansion, that was featured in films and television shows, including the Bells of St. Mary's, Rocky V, and others. It had erroneously been dubbed "Wayne Manor", as it was thought the house had been used in the Batman TV show, but in fact an adjacent residence was the site used for Batman. The historic mansion was destroyed by fire in October 2005 during a renovation by the Hammers.[13][14]

On May 30, 2017, he married Misty Millward.[15]
