Skype has announced that it plans to create 400 new vacancies across five cities, initially recruiting in London and Stockholm.

The fast growing voice and video calling over internet business will also later create posts in Tallinn, Estonia; Prague, Czech Republic; and Palo Alto in California.

Once all positions are filled the company will reach approximately 1,600 employees worldwide, Skype's VP of product and design told the BBC.

Recruitment in London will support the launch of a new technology centre in the Capital, which will increase Skype's number of employees in the city by 40 percent to 330 posts.

The new roles will cover software engineering, product management and design.

"We have on project about big data, which is making use of data that our users generate when using the product to improve the quality of products we offer," said Rick Osterloh, Skype's VP of product and design.

Skype also confirmed that its decision to recruit in London was not influenced by the UK's desire to implement legislation that would use its services to monitor people.

This news comes shortly after Yahoo announcing that it will be laying off approximately 2,000 workers.

"Today's actions are an important next step toward a bold, new Yahoo - smaller, nimbler, more profitable and better equipped to innovate as fast as our customers and our industry require," said Scott Thompson, CEO of Yahoo.
