Twitter reportedly set to make company-wide layoffs one week into Dorsey's reign as CEO

Twitter's 4,200 employees welcomed Dorsey's return to the company as permanent chief executive only last week and one of his first duties will be to oversee the restructuring of its engineering division which makes up almost half of its staff.

According to reports the staff cuts are intended to make the engineering department leaner and more efficient and it is likely that many of the staff affected by redundancies will be engineering staff.

The micro-blogging site has suffered from stagnating growth over the last two years however its engineering division has more than doubled from the 2,000 staff it had in 2013, leading to claims that those close to the company felt it was too bloated.

Commenting on reports of next week's redundancies Twitter has stated to a number of media publications that "we're not commenting on rumour and speculation".

The rumours may have gained traction following a conference call to investors on Monday in which Dorsey said "there’s a huge desire for more efficiency, and there’s an opportunity to really raise the bar on our execution”.

Dorsey, a Twitter cofounder, is now in his second stint as Twitter chief executive having served in the position from 2007 to 2008. His reappointment has tasked the 38 year-old with reviving the battered social media giant which has suffered greatly from a stagnating user growth.

One of the first changes designed to help regenerate Twittter came last week with the roll out of its "Moments" feature which has been created with new users in mind and will make it easy for users to browse the biggest stories on the social network regardless of who they follow.
