Cryptography Operations Engineer

Join Barclays in Cryptography Operations within the Chief Information Security Office (CISO), where you will play a critical role in safeguarding encryption keys and cryptographic services that support secure, multi-tenancy encryption across multiple enterprise applications.

This is a hands‑on role for an engineer with excellent knowledge of symmetric and asymmetric cryptography, cryptographic algorithms, and policy‑driven security controls. You will work extensively with Hardware Security Modules, using Thales and Entrust vendor tools, and be responsible for operating and supporting production‑grade cryptographic applications and key management solutions  will also need to be comfortable working across complex infrastructure environments, with familiarity in both Windows and Linux servers.

This is an excellent opportunity to grow technical and service managements capability in Cryptography within a supportive engineering environment.

The role follows anchor days on Monday and Tuesday and operates on standard UK hours (9 AM–5 PM), with 24/7 on‑call support rotation. The role will require off site working to support the implementation of equipment within data centres.
