Until recently, Mashiko was the vice president of finance at Western Digital, a global leader in data infrastructure. There, she led the worldwide consolidation of three legacy ERP systems-Western Digital and two of its large acquisitions, SanDisk and Hitachi Global Storage Technologies-onto the cloud.

She left Western Digital late last year to become the CFO of Hardinge, a 120-year-old company that designs, manufactures and distributes machine tools in more than 65 countries across North America, Europe, and Asia. The company was acquired by a private equity in 2018. For Mashiko, part of the appeal of joining Hardinge was the opportunity to transform the company's processes and systems and eventually take it public again.

She recently talked about her experience at Western Digital on Oracle's podcast, The General Ledger, hosted by Kimberly Ellison-Taylor, founder and CEO of consulting firm KET Solutions and the former chairman of the American Institute of CPAs.
