Jack Dorsey is back full-time at Twitter, leading product development as executive chairman.

Dorsey, who is Twitter’s chairman and one its co-founders, has been in talks for the new daily responsibilities since at least last week.


Twitter Chief Executive Dick Costolo announced the new position for Dorsey in a tweet Monday morning, writing: ‘Excited that Twitter Chairman @jack will be returning to the company day-to-day leading product as Executive Chairman.’

Dorsey followed up with a tweet of his own about the move, saying, ‘Today I’m thrilled to get back to work at @Twitter leading product as Executive Chairman. And yes: leading @Square forevermore as CEO. #200%’

Square is a mobile payment company that helps retailers charge for goods using smartphones and tablet computers instead of cash registers and other traditional credit and debit card readers.

Dorsey co-founded Square, which launched last May, and has been the start-up’s only chief executive.

Twitter spokeswoman Carolyn Penner called Dorsey’s move an example of how Twitter’s three co-founders -- Ev Williams, Biz Stone and Dorsey -- step into roles as needed.

‘As executive chairman, Jack will dive in to work with more than 450 people, led by an experienced executive team,’ Penner said. ‘The timing is fortuitous; not only is Twitter experiencing record growth, but we also now have a new infrastructure that will keep us ahead of that growth and enable us to launch products that will make Twitter more instant, simple and always present.’
