Full biography

Tom Rosamilia is Senior Vice President of IBM Systems. In this role, Mr. Rosamilia has global responsibility for all aspects of IBM's middleware, servers and storage as well as the Company's global Business Partners organization.

For 18 months prior to his leadership of IBM Systems, Mr. Rosamilia served as Senior Vice President of IBM Systems and Technology Group and IBM Integrated Supply Chain, where he led IBM’s semiconductor, servers, storage, and the system software business; all of IBM’s supply chain; and the company’s Global Business Partners organization. During that time, he oversaw the transformation of IBM’s Systems & Technology Group business to better address clients' higher-value, data-driven IT requirements. This included making major investments in strategic businesses and initiatives while exiting businesses that were not aligned with current and emerging client demands.

For example, in 2013, Mr. Rosamilia helped to lead the creation of the OpenPOWER Foundation, a collaboration with Google, Tyan, Mellanox and NVIDIA for open server product design and development.  Mr. Rosamilia has also overseen the divestiture of IBM’s global semiconductor manufacturing business to GLOBALFOUNDRIES and the divestiture of IBM’s x86 server business to Lenovo. These changes are fueling renewed vitality in what is now the IBM Systems business. 

With an IBM career that spans more than 30 years, Mr. Rosamilia joined the company in 1983 as a software developer.  Following a number of leadership roles in the Software group, he became General Manager of IBM’s WebSphere software division.  In 2009, Mr. Rosamilia joined IBM Systems & Technology Group as General Manager of System z and, soon after, Power Systems as well.  In this role, he was responsible for all facets of both businesses, including strategy, marketing, sales, operations, technology development and overall financial performance.  Prior to that, he was Vice President of Corporate Strategy and General Manager of Enterprise Initiatives, responsible for IBM’s strategic direction and for developing the company’s path forward in the new era of computing.

Mr. Rosamilia received his bachelor's degree from Cornell University, with majors in computer science and economics.  In 2004, he completed the IBM Strategic Leadership Forum at Harvard Business School. Mr. Rosamilia has also served on the boards of the United Way of Dutchess County, the United Way of Silicon Valley, the Silicon Valley Manufacturing Group and the California Manufacturing and Technology Association.
