Bromley Council have filled a child services director job left vacant for over a year, during which time Ofsted condemned the borough for "widespread and serious failures" in its child services.
Ade Adetosoye OBE, 46, is joining Bromley Council as deputy chief executive and executive director of education, care and health.
He will lead the council's social care, education, housing and health services, moving on from a similar role at the City of London Corporation.
The post has been vacant since Terry Parkin departed in May 2015.
He was in the role for two years and eight months and received £96,000 compensation when he left.

The report highlighted that "the lead member, the chief executive and the interim director of children’s services do not have a clear understanding of the strengths and weaknesses of children’s services".
Council leader Stephen Carr said: "Ade’s experience and energy across social care as a whole will provide a significant fillip to our services.
"I am confident that Ade’s ability in transforming services means he has the skills to fulfil this vitally important role for the Council.
"He demonstrates just the right energetic pace we require to lead on our ambition to transform children's services."
Arrangements are in place to confirm a formal start date.
