About Jay Kruemcke

Jay has had more than twenty years of experience in the information technology industry. Starting from a rather humble beginning at IBM, Jay became a mainframe systems support programmer. Eventually Jay joined the AIX operating systems development team early in that product's development. Jay leveraged technical skills that he built in systems management to establish himself as a member of the IBM Austin Executive Briefing Center. His expertise in systems management with the SAP ERP system enabled his first product management role, as the owner of the Tivoli management product for SAP. Over the next three years he established that product as a success with the help of a strong development team. Jay returned to AIX in a product management position initially focusing on managing new requirements for the AIX operating system. Jay established himself as a subject manager expert in AIX and Power Systems virtualization and became a frequent guest at conferences around the world. Jay succumbed to the dark side and spent four years in IBM marketing in which he introduced AIX version 6 and AIX version 7 and many product innovations including the first every open beta program for an AIX release and a significant restructuring of the AIX offering structure and prices. Jay was part of the cloud software development organization and and focused on managing development engagements for clients deploying clouds using Power Systems servers with PowerVC and related products. In March of 2016, Jay retired from IBM and started in a new role as a product manager for SUSE, the Open Software company.
