Ashton Kutcher has signed on as a product engineer with the world's biggest PC manufacturer.

The Two and a Half Men star, an avid investor in new technology, has been hired by bosses at China's Lenovo Group to help oversee the launch of the company's Yoga lines of tablet devices.

The actor says, "This partnership with Lenovo brings together my love of technology and design that makes your life better. I can't wait to dig in and help Lenovo develop future mobile computing products, starting with the Yoga Tablet."

He will reportedly help with decisions into design, software and usage, as well as acting as a spokesperson.

Reports earlier this year (13) suggested Kutcher, who portrayed Apple founder Steve Jobs in a recent biopic, will be paid $10 million (£6.67 million) for the deal.
