Nokia’s Group COO has left the company just over six months after the role was created.
Monika Maurer plans to pursue new opportunities, the Finland-based vendor said.
Maurer moved to Nokia as part of its acquisition of Alcatel-Lucent in 2015, and initially ran the combined fixed network division.
She is being replaced by Joerg Erlemeier, who steps up from his position as Senior Vice President, Nokia Transformation, today (11 December).
Erlemeier (pictured) has spent over 20 years working in a variety of positions at Nokia, including heading up the Middle East and Africa region and being COO of the Mobile Networks business unit.
The Group COO role was created in April this year as part of a shake-up that saw the departure of Mobile Networks President Samih Elhage.
CEO Rajeev Suri said: "I want to thank Monika for her contributions to Nokia, and Alcatel-Lucent before that.
“I warmly welcome Joerg to the Group Leadership Team (GLT), and look forward to working together to further strengthen our disciplined operating model.”
Nokia saw sales decline 10 percent in 2016 and they are down four percent to €16.5 billion in the first nine months of this year.
After a particularly difficult Q3 that saw revenues fall seven percent, CEO Rajiv Suri warned pain within its core mobile networks business is set to stretch into next year.
