System Engineer (Linux & Red Hat Operations) in Nottingham

About the Role

Contract type: Permanent. Hours: Full‑time, 35 hours. Location: Head Office, Nottingham (Hybrid working, minimum 2 days per week). 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.

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.
