Job description

A global technology focused business is seeking a Director level Enterprise Security Architecture leader to take ownership of security architecture direction and technology strategy within a large, complex international organisation.

This is a leadership and thought-leadership position rather than a day-to-day hands-on security architecture role. You’ll lead a team of specialist security architects across network, cloud, AI and enterprise security, while acting as a trusted adviser to the CISO and senior technology leadership.

You’ll shape the organisation’s approach to emerging technologies and security tooling, own architectural standards and design patterns, and provide strategic input at the inception of major transformation programmes. You’ll also engage with external industry forums, bringing new thinking and market developments back into the organisation.

The role will suit a security architect with significant enterprise security architecture experience, strong executive presence and the technical breadth to challenge senior specialists. Experience across cloud, networks, AI and modern security technologies would be highly relevant, alongside familiarity with frameworks such as TOGAF or SABSA.

The role offers hybrid working in either Reading or Central London. Full relocation and visa sponsorship can be offered to exceptional candidates looking to relocate to the UK.
