Veteran IBM executive Bob Greenberg is the new senior state executive for Big Blue.

Greenberg replaces Rusine Mitchell-Sinclair. She resigned August 1 to take a position with a Triangle-area Girl Scouts organization.

“This is one of the largest sites for IBM in the world and we have a rich history of volunteerism and community leadership to build upon,” Greenberg said in a statement. “I will be working with local and state leaders to share the IBM message and brand as we look for ways we can work together to improve our community and the state of North Carolina."

Greenberg, who recently celebrated his 30th anniversary with the company, was traveling and unavailable for comment on Thursday. Employees were told of his appointment in an internal announcement last week.

Greenberg and his family have lived in Raleigh for 10 years.

As the top IBM executive in North Carolina, Greenberg will be responsible for the firm’s operations in the research triangle area that includes more than 11,000 employees. The Triangle is home to the most IBM employees in one region.

Greenberg will keep his title as general manager of IBM Information Technology Optimization, which is part of IBM’s Global Technology Services group.

He also will be responsible for all IBM cross-divisional functions, programs and policy implementation, the company said in a statement.

His other positions at IBM have included vice president of IBM Server and Storage/Data Services products and chief information officer and vice president of on-demand technology enablement.

Other duties for Greenberg include serving on the IBM Integration and Values Team, the Information Global Technology Leadership Board and the IBM technology Board of Governors.
