Stevens moves from his previous position as vice president of the operating system, storage and clustering team for Red Hat. The company's previous CTO Michael Tiemann recently became vice president for open source affairs at the Linux provider.
Tiemann is booked in to present at a Gartner symposium in Sydney during the week commencing 14 November, while Stevens has a tentative booking to visit Australia on 14 and 15 November to present to customers on the next iteration of open source architecture.
Paul Cormier, Red Hat's executive vice president of engineering, said Stevens' experience in the Linux and open source world has helped not only Red Hat, but also the success of Linux itself.
"He's pioneered new technologies that have contributed to the rise of Linux as an industry-standard operating platform. Brian's vision and experience make him the right person to lead Emerging Technologies as our CTO," said Cormier in a statement.
Stevens has spent the past four years developing Red Hat's enterprise strategy. Before joining Red Hat, he was the CTO for a company called Mission Critical Linux, which he joined after spending 14 years at Digital/Compaq where he helped develop the Tru64 Operating System.
He also holds a US patent on secure methods of accessing computers through a firewall.
