* Contribute to continuous improvement of disaster recovery readiness, supporting recovery time objectives of 2 hours and recovery point objectives of zero.
* Provide mentorship and technical guidance to junior engineers and colleagues across the wider cyber and infrastructure teams.

What I'm Looking For
* Significant commercial experience in a senior Linux / Unix engineering or identity-focused role.
* Strong hands-on experience with RHEL 6/7/8/9 system administration.
* Experience implementing and managing Red Hat Identity Management (IdM).
* Strong automation and scripting capability using Python and shell scripting.
* Proven experience applying principles of least privilege, just-in-time access, and privileged access controls.
* Experience integrating Linux systems with enterprise identity, PAM, and security platforms.
* Solid understanding of networking fundamentals, including TCP/IP, DNS, and authentication flows.
* Strong documentation skills and experience producing maintainable, supportable designs.
* Excellent communication skills, with the ability to explain complex technical concepts to non-technical audiences.

Benefits
