Description du poste

A multinational defence organisation runs its security tooling on Linux, and needs an engineer to install, harden, automate and keep it available — working inside a change-controlled environment where an unexplained fix is not a fix.

What You Would Be Doing

• Installing and monitoring Linux operating systems and the applications that run on them, to the standards of a secure environment.
• Contributing to the availability, scalability and performance of the security tooling estate and the platforms underneath it.
• Building and maintaining custom systems and tools that make it possible to test, integrate, automate and monitor both custom and commercial applications.
• Preparing and defending application upgrades in front of the change management board.
• Rolling out new features and installations inside the protected perimeter.
• Writing the documentation and operating procedures for what you build, and testing them.
• Diagnosing problems in Linux systems and in how they integrate with directory services, single sign-on, web platforms and log aggregation.
• Finding the patterns behind repeated incidents and proposing the improvements that reduce them.
• Working with service management on incident, problem and change procedures.

What you would bring

• A computer science degree with at least a year as a Linux engineer, or the equivalent in practice.
• Linux server administration on Red Hat Enterprise Linux — installation, configuration and maintenance.
• Programming or scripting used in earnest for automation.
• Ansible, and comfort with virtualisation such as VMware.
• Security practice applied to Linux: firewalls, encryption, access control.
• Red Hat certification — both administrator and engineer level is preferred.
• Desirable: Red Hat Satellite and packaging, observability practice, containers with Podman or Docker, collaboration tooling, and open-source contribution.
