The role will require flexibility and travel across all time zones as it involves engagement with colleagues from all locations of the global Aviva business. It is imperative that you be a motivated self-starter who can manage your own time and commitments to the business.


You should be able to demonstrate good interpersonal skills, ability to review large amounts of data; capability to juggle many priorities and security related topics whilst maintaining an excellent level of customer service skills.


You will contribute towards the operation of the Information Security function at Aviva via the provision of domain expertise across Aviva and subsidiaries. You will be based from our Bristol office with travel to other Aviva locations.
