Twelve senior managers at Northumberland County Council will leave the authority this week as part of a management restructure.
The council said the job cuts would result in savings for the authority for the 2010 tax year.
A spokeswoman said re-organisation within departments had also played a part in the decision.
It follows the creation of a "super council" in Northumberland last year, which prompted hundreds of lost posts.
Trevor Doughty, the executive director of people and Jill Dixon, the executive director of performance, were the most senior members of staff to volunteer to leave the authority.
Jeff Reid, the leader of Northumberland County Council, said both had played an important role in the transition to the new unitary council.
"I know that I speak for everybody at the council when I wish Trevor and Jill all the best for the future and thank them for the valuable contribution they have made to Northumberland," he said.
In April 2009 the county and six district councils merged to form one authority.
Mr Reid said the council had been facing a number of external "economic pressures" including flood recovery and the Icelandic banking collapse.
He said: "We have had to take a number of difficult decisions, and whilst any job losses are undesirable, the council is working hard to minimise the number of people affected."
