IT Security and Resilience Specialist

ROLE OVERVIEW //

We are recruiting for an experienced IT Security and Resilience Specialist to join the IT Infrastructure Engineering Team. Which is part of the Technology Department, and the wider Business Services function based at the firm’s head office in London. This is a hybrid role that is both hands-on and process-focused, ensuring that our disaster recovery (DR), failover, and operational resilience capabilities are effective, tested, annually reviewed and continually improved.

The Security & Resilience Specialist will plan and execute DR and resilience testing, drive remediation activities through to closure, and ensure that evidence and documentation meet client, regulatory, and audit standards. This is not a purely administrative role; the successful candidate will work directly with infrastructure and security teams to fix issues as well as document them.

• Delivery-focused: equally comfortable running a failover test as updating\reviewing runbooks.
