System Engineer

Location:

Head Office, Nottingham (Hybrid working, minimum 2 days per week)

Due to continued investment in our Technology Operations capability, we have an exciting opportunity available for a Systems Engineer – Linux & Red Hat Operations to join our Technology & Transformation team.

We are an ambitious building society using technology to support secure, resilient and reliable services for our members and colleagues. This is a great opportunity for an experienced Linux / infrastructure engineer who enjoys improving systems, solving problems and helping make technical environments more secure, current and supportable.

You’ll join a warm and collaborative team supporting the Society’s infrastructure and wider technology estate. This is a broad Systems Engineer role first, with additional depth in Linux and Red Hat Enterprise Linux operations. Red Hat Enterprise Linux is our standard Linux platform, so strong RHEL administration experience is important from day one.

The role will also support Linux patching, vulnerability remediation, secure configuration, operating system hardening, lifecycle management, documentation, tooling and operational improvement.

We’re looking for someone proactive and practical. This is not a role for someone who only waits for tasks to be handed to them. We want someone who can analyse the Linux estate, identify risks and improvement opportunities, explain the options clearly, and help deliver safe, controlled and well-documented improvements.

All roles are hybrid based in Nottingham and include participation in an out-of-hours rota.

Here’s a taste of what you will be doing as a Systems Engineer at Nottingham Building Society:

• Linux Infrastructure Support – Support, maintain and continuously improve Linux, Red Hat and wider infrastructure services across the Technology Operations estate.
• Technical Support & Service Delivery – Provide 2nd and 3rd line support for incidents, problems, service requests, changes and project activity.
