Rima Qureshi will join Verizon as executive vice president and chief strategy officer just six months after leaving her position as head of North America at Ericsson.

Qureshi will replace Roy Chestnutt, who had previously announced plans to pursue opportunities outside of the telecom giant. Qureshi will start on Nov. 6, and Chestnutt will depart by year-end.

Qureshi will report directly to Verizon CEO and Chairman Lowell McAdam. She will oversee the development and implementation of Verizon’s overall corporate strategy, including business development and strategic investments.

Qureshi left Ericsson in May, where she oversaw the company’s North American operations and was involved in its partnership with Cisco. The partnership was announced in November 2015, and she worked closely with Hilton Romanski, Cisco’s chief strategy officer, on the deal.

Qureshi joined Ericsson in 1993, and rose quickly through the ranks of the Swedish firm. She was in charge of the company’s code division multiple access (CDMA) unit after Ericsson purchased that business from Nortel. Verizon was one of the world’s largest CDMA operators.

In between gigs, Qureshi picked up board of director seats at MasterCard and Great West Lifeco.

Qureshi will join former Ericsson CEO Hans Vestberg, who landed at the company earlier this year. Vestberg left Ericsson in mid-2016, having served as CEO for six years. He is executive vice president of Verizon’s Network and Technology operations.

Ericsson earlier this month removed the “interim” tag from Qureshi’s successor Niklas Heuveldop.
