Barclays has announced that chief operations and technology officer Shaygan Kheradpir is to leave the banking group to join Juniper Networks as CEO.
Kheradpir will depart to take on his new role at the US networking equipment firm, starting on January 1st 2014. Head of compliance Sir Hector Sants is also set to exit the firm.
Kheradpir was promoted to chief operations and technology officer with responsibilities for the entire Barclays group in March 2013. He had previously been chief operating officer for the bank's retail and business banking division, having joined in 2011. In this role Kheradpir helped develop the PingIt mobile payment solution, as well as supporting the group-wide cost transformation project, Transform.
Kheradpir will now succeed current Juniper CEO, Kevin Johnson, who will retire and remain as a board member.
Barclays CIO Daryll West, who recently joined from rival Lloyds, will act as interim chief operations and technology following Kheradpir's resignation.
Antony Jenkins, group chief executive commented: "Shaygan has made a huge contribution to our innovation and technology agenda and the elements of Transform which his team are delivering have real momentum.
"He has infused his colleagues in operations and technology with a spirit of creative thinking and exploration which Barclays will continue to benefit from long after he has moved on."
Meanwhile Sants, who has served as head of compliance and government and regulatory relations, will also leave the firm, having been on sick leave since the beginning of October. The bank said that he had been suffering from "stress and exhaustion", and had decided to resign.
Allen Meyer, head of compliance, corporate and investment Banking will cover his role on a temporary basis.
An internal and external search will now be launched for both posts.
