Job Description
Senior IT Infrastructure Engineer | World of Books | UK
We’re the world’s largest seller of pre-loved books — a certified B Corp generating £200m+ revenue, with operations across the UK, US and Hungary. We’ve rehomed over 100 million books since 2002, and our technology is what makes the whole thing work at scale.
We’re looking for a Senior IT Infrastructure Engineer to join our Technology team — someone who takes genuine pride in keeping complex systems running well and has the expertise to make them better.
The role
Reporting to the Senior IT Manager, you’ll own a broad and genuinely varied infrastructure remit. Day-to-day, that means delivering high-quality support across 1st, 2nd and 3rd line, maintaining and improving our Microsoft environment, and leading infrastructure projects end-to-end.
You’ll be the person colleagues across the business turn to when something complex needs diagnosing, when a project needs leading, or when a system needs tightening up. You’ll work across our UK sites and in close collaboration with teams in the US and Hungary, so strong communication and a customer-first mindset matter as much as your technical credentials.
What you’ll be doing
• Resolving complex hardware, software and network issues across the group, working to SLAs and making sure users feel genuinely supported
• Installing, configuring and maintaining Microsoft Windows Server, Microsoft 365, Active Directory and Hyper-V virtualisation environments
• Leading the planning, implementation and testing of infrastructure projects — server migrations, system upgrades and cross-business initiatives
• Performing advanced system monitoring, performance tuning and proactive maintenance to keep infrastructure available, optimised and secure
• Providing end-user support for Windows laptops, desktops and mobile devices
• Creating and maintaining clear documentation — system configs, technical procedures, project plans and user guides
• Collaborating with cross-functional teams on complex technical issues and staying ahead of industry trends to recommend improvements
• Enforcing and promoting IT security best practices across everything you do
What we’re looking for
• Proven experience supporting enterprise-level IT infrastructure, with strong hands-on expertise in Microsoft Windows, Microsoft 365, Active Directory and Hyper-V
• Solid knowledge of networking concepts, protocols and IT security practices
• Comfortable working across 1st, 2nd and 3rd line support and managing a service desk queue effectively
• Experienced in leading and managing IT projects — defining scope, timelines, deliverables and seeing them through to completion
• Familiar with ITIL best practices and experienced working within an ITIL framework
• A strong communicator who can explain technical issues clearly to non-technical colleagues
• Sharp analytical thinker with excellent attention to detail and a methodical approach to problem-solving
• Relevant certifications (Microsoft Certified: Azure Administrator Expert, MCSE, CISSP or equivalent) are a plus
Why World of Books?
• A mission that genuinely matters — B Corp certified, sustainability at the core, 100 million books given a second life
• A varied, hands-on role at a business that runs on technology — what you maintain and build has real operational impact
• A collaborative, supportive technology team with a broad and interesting infrastructure estate
• A fast-growing business backed by Livingbridge PE, investing seriously in its technology and people
• Operations across three countries — the problems are interesting and the work is never monotonous
If you’re a technically strong infrastructure engineer who wants a role where your work keeps a £200m business running — and growing — we’d love to hear from you.
