As a special adviser, Caine is paid an annual salary of £69,266. 
From 1991 to 1995, Caine was special adviser to two Secretaries of State for Northern Ireland: Peter Brooke and Sir Patrick Mayhew. Caine then worked as Assistant Director in the Conservative Research Department from 1998 to 2007, specialising in Northern Ireland. Caine spent time as adviser to John Major and chief speech writer for William Hague.
From March 2007 to December 2009, he was a director at lobbying firm Bell Pottinger Public Affairs (BPPA). His appointment was "a coup for BPPA, providing the agency with a valuable link to Cameron's inner circle".
On leaving BPPA, Caine rejoined the Conservatives as Chief of Staff to Owen Paterson in the run up to the 2010 general election. He was due to return to BPPA after the election, but instead took up a position as Paterson's special adviser.
In 2008, Irish Times journalist Frank Millar commented that "Cameron's surprise embrace of UUP" would leave the DUP "smarting". He writes:
- Jonathan Caine, a former special adviser to secretaries of state Peter (Lord) Brooke and Patrick (Lord) Mayhew, recalls discussing the issues and the difficulties with the young Cameron when they worked together in the Conservative Research Department in the early 1990s. "It was hard to imagine such progress back then," says Caine: "But he has always had a genuine desire to see Northern Ireland politics normalised." Lord Trimble and influential shadow Northern Ireland secretary Owen Paterson are among those who have been working behind the scenes to encourage Cameron's belief that - courtesy of the Belfast and St Andrews Agreements - the opportunity exists now to move beyond "the old issues".
