Telstra Corp is farewelling another US executive, with group managing director of marketing Bill Stewart to leave at the end of March.
Outgoing Telstra chief executive Sol Trujillo announced on Friday Mr Stewart would leave the telco to return to his home and family in the US.
Mr Stewart will be replaced in the role by current group managing director of wholesale, Kate McKenzie.
A replacement for Ms McKenzie would be announced in the coming weeks, Telstra said.
Mr Stewart joined Telstra in 2005 to head a newly formed strategic marketing group, responsible for corporate strategy, mergers and acquisitions, pricing, brand management and advertising.
''Under Bill's leadership, Telstra has delivered increased customer satisfaction across all our business units and services,'' Mr Trujillo said in a statement.
''Bill and his team have helped deliver increases in market share, improved margins, lower churn and high strike rates for sales.''
Mr Trujillo will leave Telstra on June 30.
Fellow Americans, former chief operating officer Greg Winn and former corporate affairs boss Phil Burgess, have also resigned in the past six months.
Telstra shares closed down 9 cents, or 2.9%, at $3.06.
