Bond, the membership body for development charities, has appointed Tamsyn Barton as chief executive.
Barton spent nine years until 2010 working in a variety of roles at the Department for International Development, including as head of its EU department.
More recently, she was director-general responsible for lending operations outside the EU and candidate countries at the European Investment Bank, before spending two years representing the EIB on the board of the European Bank of Reconstruction and Development.
She replaces Ben Jackson, who left Bond in October to join United Purpose as global director of innovation and partnerships.
Tim Wainwright, chair of Bond, said Barton would bring a wealth of experience to the role.
"Tamsyn has worked at a senior level in government, NGOs and international financial institutions, and I believe this diverse experience will be invaluable in continuing Bond’s work of transforming the landscape for international development in the years ahead."
Barton said: "I believe that the role civil society and Bond members can play in improving the lives of people living in poverty is enormously important, particularly in this period of huge change for the sector. I am really looking forward to working with members and helping them to increase the impact of the work they do."
Barton, who will be paid £88,000 a year, will join Bond on 27 February.
Before working in development, she worked in academia and her publications included a book on the history of astrology in the ancient world.
She is a trustee of the School of Oriental and African Studies.
