Clive Wright, who already works for the council, has been promoted in the wake of the departure of Shirehall's former boss Kim Ryley, who left to join neighbouring Cheshire East Council in July.
Mr Wright, who is currently the council's area director for the central region covering Shrewsbury, has been named as Shirehall's new operations director.
He has taken up the new role with immediate effect.
Mr Wright will also take on the role of head of paid service from David Taylor, who has been doing that job on an interim basis since Mr Ryley's departure.
Mr Taylor is due to retire in the spring.
Councillor Keith Barrow, council leader, said: "David Taylor, our interim head of paid service, will be stepping down from that role on November 30.
"We are very grateful to David for taking on this important role and for the professionalism and skill that he has exhibited throughout."
He added: "At the same time, I am pleased to announce that Clive Wright, our newly appointed operations director, will assume the head of paid service role."
Mr Wright, 49, joined Shropshire Council from Walsall Council last year and has 15 years of senior management experience.
