Dutch insurance group Aegon has hired a new chief technology officer (CTO) from Citigroup. The position has been vacant since June last year after Mark Bloom left the company to pursue other opportunities and continue his non-executive role at Freddie Mac. Deborah Waters (pictured) will join the insurer as CTO and member of the management board of Aegon N.V. Waters comes from Citigroup, where she held various technology leadership positions. Most recently, she served as Citi's global head of private bank operations and technology.
