Mr Gay will be responsible for completing and capitalising on the bank’s $70 million technology transformation program, as well as overseeing IT infrastructure and extending "agile innovation capabilities".
Between 2009 and 2012, Mr Gay worked as GE Capital Group’s chief technology officer, where he led a three-year, $150 million transformation program, and most recently was director of GE’s FastWorks, lean and strategic program delivery.
Mr Gay said he was excited to be joining an organisation where he can combine his financial services expertise with his passion for technology to drive growth plans.
“ME Bank is a young and nimble organisation with an appetite to innovate and disrupt,” he said.
ME Bank chief executive Jamie McPhee said the appointment of Mr Gay was important given the lender’s aspiration to become a leading digital bank.
“Our transformation program is a major enabler for growth, increasing our capability and improving our operational efficiency – our ability to compete,” he said.
“Mark has a unique chance to realise the opportunities transformation provides, setting the course for exponential growth in future years.”
Mr Gay will begin his new role on 27 January. He will replace Kathryn Hawkins, who will finish this month.
