Following seven years at Hammersmith & Fulham Council, where he is director of comms, policy and performance, Jones is set to take up the new post in November.
He replaces former director of comms George O’Neill, who left in the spring to become director at charity L’arche London.
Jones pointed to "major transformation" in the borough as one of the main points of focus when he joins: "We’re seeing huge ambition in terms of regeneration, in places like Tottenham, and we need to make sure the comms matches that ambition."
More than £1bn has been earmarked for Tottenham with the target of building more than 10,000 homes and creating 5,000 new jobs by 2025.
"The challenge for me will be around ensuring that our communities are involved and engaged in what’s happening and I can’t think of a bigger or better job in local government right now," Jones added.
Haringey’s deputy chief executive, Zina Etheridge, said: "Simon has a wealth of experience in policy, communications and journalism, and we’re delighted that he will be joining Haringey as our assistant director of communications.
"We had a very strong field of candidates, who were universal in their enthusiasm for the role, describing it as one of the best in local government. This says a great deal about the exciting challenge of working at Haringey, and the many opportunities ahead of us."
Before joining Hammersmith & Fulham Council, Jones was senior editor-in-chief at newspaper company Trinity Mirror's Southern division.
Jones added that the matter of his replacement at the council was "still to be discussed".
