Two more BlackBerry executives are headed for the door under sweeping changes from its new leader.

The smartphone maker says Rick Costanzo, executive vice-president of global sales, and Chris Wormald, vice-president of strategic alliances, will leave their roles.

The departures come as interim chief executive John Chen pushes ahead with plans to reshape the money-losing Canadian technology company.

Costanzo was responsible for overseeing the team responsible for the international presence of the BlackBerry smartphone, while Wormald oversaw licensing and acquisitions.

Both executives held various other positions at the company over the years.

On top of that, another high-ranking employee has landed a job at public relations company Hill and Knowlton.

A press release from the firm said Mark Cameron, who was BlackBerry's director of global public policy, has joined their
team. BlackBerry did not immediately confirm whether he had left his role.

Cameron began working at BlackBerry in 2011 and oversaw the smartphones sales to the government and public sectors.

BlackBerry will report its third-quarter financial results on Friday.
