In the role Mandhar will take responsibility for commercial content, newspaper production and circulation, events and commercial operations.
She joins the publisher from OMD UK, where she was most recently managing director. It is not yet known who will be replacing Mandhar at OMD.
Prior to this she was managing director of MediaCom's entertainment division Ted, as well as managing director of MediaCom’s employer brands arm Career and general manager at TMP Worldwide/Monster.com, where she led the agency’s commercial arm.
Mandhar’s appointment comes just days after the publisher appointed Chris Forrester, formerly the country manager of Spotify UK, as its first chief revenue officer.
Speaking of her appointment, Mandhar said: "I am delighted to have joined The Telegraph, particularly at such a crucial time, when they are diversifying revenue streams and continuing to truly deliver high quality journalism. I look forward to being part of the business as it continues to move into the future."
Hugh added: “It’s wonderful to welcome Aki to The Telegraph. Her wealth of experience and industry knowledge make her a key addition to the company and she will play a major role in the commercial development of our business.”
