The firm which bought Skype for more than $8m has accidentally made the announcement by way of a job listing. The software development engineer position is within a new Xbox Skype team suggesting development will be underway soon.
The job listing said: "We’re building the next generations of our products and technology right here in London and Skype is looking to hire a Software Development Engineer to contribute to the development of our experiences on Xbox."
"You will be designing and developing next generation scalable services for millions of end users." it added.
The listing mentions Windows 8 Metro and Xbox development experience would help. We assume that the app would utilise the microphone built-in to the Kinect sensor.
Microsoft announced its financial results for the first quarter of the year which saw Xbox and entertainment sales fall. It reported a drop of 16 percent revenue down to $1.62bn.
