Stein started his career at Marks & Spencer in 1990. In 1994 he joined Mars as a project manager, working on data warehousing and financial systems, and between 1996 and 2001 Stein worked at Ernst & Young leading a number of major IT and change programmes in the financial services, retail and utility sectors.

From 2001 to 2006 Stein worked at Vodafone, becoming IT director for Vodafone UK in January 2004: prior to that he was Vodafone’s UK network director and global IT strategy and architecture director. Stein rejoined Marks & Spencer in July 2006 as IT director.
