Milosevic will report directly to Simon Buckby, managing director of Champollion Group, and will lead Champollion digital’s team of web developers, digital designers and consultants.
She will work predominantly across the Scope and Skills Third Sector accounts, while having responsibilities across the group as a whole.
Milosevic's previous jobs include senior digital positions at charities World Society for the Protection of Animals and the Catholic Agency For Overseas Development (CAFOD).
As head of digital at Save the Children, she led the digital integration of campaigning and fundraising across the organisation and has led on digital campaign initiatives for Make Poverty History in 2005 and Put People First in 2009.
Milosevic started her career as a journalist, working in Serbia before joining the BBC World Service.
Champollion, which specialises in making public policy arguments, launched its digital arm in November 2011, signing up Ed Miliband’s former new media adviser Alex Smith as a consultant.
Laura Brodie, director, Champollion Group, said: ‘Too often digital is seen as a bolt on, rather than a discipline that underpins all comms, whether that is traditional media or public affairs.
‘A truly integrated approach across all media disciplines will become even more important in the next few years as technology moves rapidly towards greater personalisation, whether that is building brand awareness, campaigning or stakeholder engagement. This is a really exciting time in the company's growth for both third sector and corporate clients.’
The independent agency’s current clients include City of London Corporation’s charity City Bridge Trust, iCITY and Give More.
