Join Barclays as a Cryptography PKI and SSH Engineer, where you’ll be responsible for designing, implementing, and managing secure cryptographic and access control systems that protect the organization’s infrastructure and data. Your main responsibility will be to ensure that all encryption, key management, and secure communication processes comply with internal security policies and external regulatory standards.

You will collaborate closely with system, network, and security teams to integrate Zero Trust principles, manage SSH tunneling, harden systems, and ensure secure connectivity. This role includes participation in on-call support (24/7) to respond to urgent incidents, resolve cryptographic or access failures, and maintain service continuity.

To be successful, you should have:

•  Ability to design, implement, and maintain SSH-based secure frameworks aligned with banking security policies and regulatory requirements.
• Deep understanding of encryption standards and secure key management practices, primarily centred around PKI and SSH.
•  Strong understanding of Unix/Linux/Windows system administration.

Other highly valued skills include:

•  Networking and security troubleshooting.
•  Scripting capability (e.g., Python, Go).
•  Working knowledge of relevant financial security standards such as ISO 27001, NIST, and FIPS 140-3.

You may be assessed on key critical skills relevant for success in the role, such as risk and controls, change and transformation, business acumen, strategic thinking, and digital and technology expertise, as well as job-specific technical skills.

This role is based in Knutsford.
