Job description

What You’ll Do

• Take ownership of our core server estate, managing and optimising physical and virtual servers - including cutting-edge hypervisors like VMware VCF and ESXi.
• Bring infrastructure to life through automation, using Terraform and Ansible to build, deploy, and manage platforms at scale.
• Keep our data flowing and protected by administering enterprise-grade storage solutions (SAN/NAS, object storage) and driving reliability with technologies such as Veeam.
• Engineer high‑performing, resilient networks, configuring and fine‑tuning technologies across LAN/WAN, SD‑WAN, VLANs, BGP/OSPF, VPNs, load balancers, firewalls, and more.
• Be the heartbeat of platform reliability, delivering proactive monitoring, rapid troubleshooting, performance optimisation, and smart capacity planning.
• Jump into action when it matters most, contributing to incident response, conducting deep‑dive RCAs, and supporting 24/7 on‑call environments that keep critical systems running.
• Automate the manual and eliminate the mundane, building self‑service tools and workflows that boost efficiency and empower teams.
• Champion security at every layer, implementing robust controls across patching, vulnerability management, hardening, zero‑trust, IAM, and network segmentation.
• Partner with brilliant minds across the organisation, working closely with SRE, security, application, and architecture teams to deliver new services, large‑scale changes, and complex migrations.
• Help shape our future resilience, contributing to DR strategy, running test exercises, and designing architectures built for high availability and fault tolerance.

You’re someone who thrives in complex technical environments and loves getting under the hood of enterprise infrastructure. You bring a blend of solid engineering fundamentals, problem‑solving instincts, and a curiosity to keep learning. Here’s what you’ll bring to the team:

Your Profile

• A deep understanding of enterprise IT infrastructure - from compute and storage to backups, networks, operating systems (Windows/Linux), and middleware.
• Strong knowledge of Active Directory Domain Services, with the ability to design, manage, and troubleshoot directory‑based environments.
• Hands‑on virtualisation expertise, especially with VMware vSphere and VCF.
• A confident grasp of networking essentials, including TCP/IP, DNS, DHCP, routing, switching, and firewalls.
• Experience with Infrastructure as Code, using tools like Terraform and Ansible to build and manage environments more efficiently.
• Scripting capabilities in PowerShell, Bash, or Python - and a willingness to automate anything that can (and should!) be automated.
• Familiarity with backup and disaster recovery strategies, high‑availability designs, and business continuity principles.
• Knowledge of modern storage solutions such as vSAN, NAS, and object storage platforms.
• A proven track record of solving tricky, multi‑layered technical issues, often across several technologies at once.
• Excellent communication skills, with the ability to translate complex technical concepts into clear, understandable language for non‑technical stakeholders.
