He then was called to the Bar in 1985 and served as a legal advisor to the Motor Agents Association for three years before joining the government in the Office of Fair Trading in 1989. In 1993 Jones transferred to the Treasury Solicitor's Department, briefly into the division working with the Department for Transport, then as Legal Secretariat to the Law Officers from 1994 until 1998. In 1998 Jones became deputy legal advisor to HM Treasury.

On 1 March 2014, Jones was appointed the Treasury Solicitor, replacing Sir Paul Jenkins on his retirement.

A spokesman for the Attorney General's Office confirmed the resignation but refused to comment.
After observing a 3-month pause in accordance with advice from the Advisory Committee on Business Appointments, Jones took up a position as a senior consultant with the international law firm Linklaters from 15 March 2021.
