Vodafone’s Group Head of Cloud and Automation Fran Heeran left the telco operator to return to Nokia. Heeran will take on the role overseeing Nokia’s telco cloud business.

Heeran held a number of positions at Alcatel-Lucent for a little under five years until he left for Netcracker when Alcatel-Lucent was acquired by Nokia in 2016. He served as the senior vice president and general manager of SDN and NFV at Netcracker for 14 months before departing for Vodafone.

During his tenure at Vodafone he initially served as the head of the operator’s network virtualization business overseeing SDN and NFV. Heeran’s role was expanded in mid-2018 to include all of the operator’s network, cloud, and IT infrastructure activities in a reorg.

This is a significant loss for Vodafone, which has seen a number of executive departures in the last few months from its London headquarters where Heeran also worked. In November, its head of cloud and infrastructure center of excellence Pablo Jejcic left to head cloud engineering at the London Stock Exchange, according to his LinkedIn profile. Karine Brunet, Vodafone’s director of technology shared services, left in December to become the CMO of Capgemini.

In addition, the operator lost the CTO of Vodafone Deutschland Eric Kuisch last October. Kuisch has since been replaced by Gerhard Mack.

And it seems the operator is undergoing other big changes. The Register reported yesterday that Vodafone’s U.K. CTO Scott Petty sent out a memo to its employees announcing organizational changes brought on by real estate changes. According to the report, the operator is vacating a number of its U.K. offices to save about $27 million over the next three years. This means a large number of employees will be asked to relocate to a new office, in some cases hundreds of miles away.

This is Nokia’s second major hire this year. A few weeks ago it named Sandra Motley as the president of its fixed networks business. Motley took over from Federico Guillén, who was named president of Nokia’s customer operations for Europe, the Middle East, Africa (EMEA), and Asia.

These appointments were part of a larger corporate restructuring that the vendor first announced in November 2018. Nokia President and CEO Rajeev Suri attributed these changes to the telecom’s industry push into 5G services. The vendor also said it is trying to cut $800 million in costs by 2020, which could result in thousands of job cuts.
