Dave Mosley
Chairman and Chief Executive Officer
Dr. Dave Mosley is Chairman of the Board and Chief Executive Officer of Seagate, a global leader in mass-capacity data storage with more than 30,000 employees and a smart manufacturing footprint spanning three continents.
As CEO since 2017, Dave has led Seagate through a period of strategic transformation, doubling the company’s shipped storage capacity and driving innovation across the company — including the launch of the world’s first hard drives using heat-assisted magnetic recording (HAMR) to support the massive need for AI data storage.
Dave joined Seagate in 1996 with a doctorate in solid-state physics from the University of California, Davis. Over his decades-long career, he has held senior leadership roles across multiple company disciplines and functions, including research and development, sales and marketing, and operations.
Elected to the Seagate board in 2017 and named Chairman of the Board in 2025, Dave is guided by the principle that data is much more than the technology and innovation that underpin it. It's the foundation of human connection, creativity and progress. Every photo, scientific breakthrough, cinematic masterpiece and story begins with data — and that data has long-term value that can only be captured when it’s stored, trusted and accessible. Dave has also served on the Board of Directors of Cirrus Logic, Inc. since 2024.
