Equipment vendor Nokia Siemens Networks (NSN) has appointed BT’s head of mobile technology as its new chief technical officer, effective July 1. Hossein Moiin will report directly to NSN CEO, Rajeev Suri.

The new role of CTO was created by NSN following its 2009 reorganisation, which included the elimination of the role of chief operating officer from January 2010. In his position as CTO, Moiin will be responsible for developing and advocating the company’s technology strategy and long-term views on network architecture.

Prior to working for BT, Moiin held positions with T-Mobile, including group vice president for technical strategy and chief architect. Moiin was also chief technologist for the Network Service Provider Group at Sun Microsystems.
