Nokia's former CEO Olli-Pekka Kallasvuo has landed a role as board chairman at Swedish TV operating system maker, Zenterio.
Zentario announced Kallasvuo's appointment on Thursday, along with another mobile heavyweight appointment, Mats Lindoff, a former CTO of Sony Ericsson, who will serve as chief technical officer.
"Zenterio's software platform is very impressive," said Kallasvuo, who was Nokia chief's between 2006 and 2010.
Of course, the ex-Nokian would say that. The Swedish company's Zentario OS Linux-based operating system for interactive TVs took its lead from a computing architecture and programming language combination that Nokia pioneered in the 1990s to tackle hardware limitations.
"Nokia chose an event-based approach and C++. At the time this was a bold decision, years ahead of competition,” according to Zentario, which hailed the OS's "modular capability and the strict use of limited software abstraction layers".
Kallasvuo joined Nokia's ranks as corporate counsel in 1980, before its first mobile phone and during a decade when Nokia experimented with a PC line called MikroMikko.
He became Nokia's chief in 2006, taking over from Jorma Ollila, under whose leadership Nokia had grown to become the biggest mobile phone maker in the world. Kallasvuo was replaced by Stephen Elop in 2010, three years after Apple's iPhone began to eat away its dominance in smartphones.
Kallasvuo remains a director of Nokia's GPS and mapping acquisition Navteq, which the company acquired in 2007 for $8.1bn. He was also elected to the board of directors at Swedish-Finnish carrier TeliaSonera in 2012.
