The Duke of Sussex will step into the role of chief impact officer, the San Francisco-based firm revealed on its website on Tuesday.
As part of his role, the duke will advocate publicly on topics related to mental health and will also be involved in initiatives including product strategy decisions and charitable contributions.
“I intend to help create impact in people’s lives,” he told The Wall Street Journal, which first reported the news.
He added: “Proactive coaching provides endless possibilities for personal development, increased awareness, and an all-round better life.”
Harry has spoken on several occasions about his own personal struggle to come to terms with the sudden death of his mother Diana, Princess of Wales, when he was 12.
He previously disclosed how he sought professional help after spending almost two decades “not thinking” about his mother’s death as he “shut down all his emotions”.
Harry again opened up about Diana’s death in the foreword of a new book, Hospital by the Hill, which is aimed at children of health workers who have died during the coronavirus pandemic.
Earlier this year, Harry and his wife Meghan Markle confirmed they would not be returning as working members of the royal family.
