He will now manage trading across the company's UK business, leading a team of 20, and will report to trading and investment director Nick Parker. Parker will continue to oversee UK trading with a focus on providing strategic trading insights to clients and agencies.
Bundock's appointment follows two other high-profile hires at Kinetic in recent weeks.
Nick Mawditt joined as global director of insight and marketing with a bid to drive planning research into consumer lifestyles, while Suzanne Hodgins joined from Manning Gottlieb OMD as UK planning director to enhance planning processes across the company.
A key part of her role will be to lead the development of Kinetic Academy, the company's proprietary planning system.
