David Holdsworth, deputy chief executive and director of operations at the Charity Commission, is to step down at the end of next month.
The regulator said Holdsworth would be leaving to take up a similar role at the Intellectual Property Office, albeit at a higher grade than in his current position.
Holdsworth, who joined the regulator in 2015 and became deputy chief executive in 2017, previously spent a decade at the Home Office in various roles, including senior operational roles in the Immigration Service.
He also spent five years in the private sector as a managing director and partnership director at two different FTSE100 companies.
The commission has posted an advertisement for Holdsworth’s replacement as director of operations, based in its Liverpool office.
The job will pay a salary of between £75,000 and £80,000 a year for the successful applicant, the advertisement says, with a closing date for applications of 17 May.
The job advertised will not include Holdsworth’s role as deputy chief executive.
The recruitment firm Gatenby Sanderson will be handling the application and interviewing process on the behalf of the commission.
Helen Stephenson, chief executive of the Charity Commission, said Holdsworth would be missed.
"David has shown great dedication and commitment to his role at the commission and has made a huge contribution in his time here, in particular to our digital transformation programme," she said.
"David has been a key part of my leadership team and has been core to the significant progress the commission has made in recent years. We are sorry to see David go, but wish him every success in his new role."
