News Corp Australia's chief digital officer has resigned after one year in the role to pursue 'entrepreneurial opportunities'.
Sheffield was promoted to the role of chief digital officer in March last year following the departure of former chief technology officer Alisa Bowen.
Sheffield took on the CDO role as the result of a reshuffle that saw the digital product and platforms team and consumer, marketing and circulations technology team folded into the Digital Networks Australia division, led by Sheffield.
Dominic Hatfield has responsibility for News Corp's technology operations as its CTO.
Sheffield had first joined the business as CEO of NewsLifeMedia in March 2012, from almost four years at Foxtel.
She will now step down to pursue undisclosed entrepreneurial opportunities.
“I’ve loved my time with News through a period of extraordinary change with so many opportunities and such wonderful content. It has been an incredible experience," Sheffield said in a statement.
“But with the business soaring I’m ready to pass the baton to an exceptional team and pursue my entrepreneurial spirit.”
Sheffield will remain with News Corp until April to assist with the handover. It is unclear who will replace her in the CDO role.
