Lead Infrastructure & Systems Engineer

Edgbaston, Hybrid (Office and Remote Working)

Medinet and its subsidiary Healthharmonie deliver a range of community healthcare services across multiple sites. Our IT team supports both organisations across all technology functions, bringing together infrastructure, systems, and end-user support under a single unified function. As the team grows and our service footprint matures, we are creating a new senior technical role to sit at the heart of the infrastructure function: a Lead Infrastructure & Systems Engineer who acts as the primary point of technical escalation for the team and leads on the ongoing development of our systems and platforms.

To serve as the principal technical escalation point for the IT infrastructure team, handling the most complex incidents and requests before they reach the IT Infrastructure Manager. Alongside reactive support, this role leads the ongoing development of our Fresh service ITSM instance, drives minor infrastructure improvements, and takes on delegated technical work from the IT Infrastructure Manager — with the explicit goal of freeing senior management capacity for strategy, team development, and organisational planning.

This is not a people management role, but someone with a natural inclination to share knowledge and bring others along will thrive here.

• Act as the primary technical escalation point for the infrastructure team — the definitive next step before issues reach the IT Infrastructure Manager
• Take ownership of the most complex, ambiguous, or high-impact incidents across the estate, driving them through to resolution
• Carry out detailed root-cause analysis on recurring or systemic issues and implement lasting fixes across the environment
• Provide authoritative technical guidance to the infrastructure team, helping colleagues develop their skills through hands-on collaboration rather than formal instruction

• Deliver minor infrastructure updates and improvements as delegated by the IT Infrastructure Manager, including configuration changes, service upgrades, and platform enhancements
• Own technical documentation for the infrastructure estate — ensuring network diagrams, runbooks, configuration records, and architecture notes are accurate and maintained
• Contribute to infrastructure projects alongside the team, particularly where senior technical input is needed to de-risk delivery
• Administer and develop the Microsoft Azure and Microsoft 365 estate — Entra , Intune, Conditional Access, Exchange Online, SharePoint, Teams, and Azure Virtual Desktop
• Manage and optimise network infrastructure across sites — switches, firewalls, VPN, Wi-Fi, and internet connectivity — with a strong focus on resilience and proactive monitoring
• Lead on security posture improvements including patch management, vulnerability remediation, identity governance, and security alerting

• Participate in the onboarding of new 1st line engineers where technical depth is needed, and be a reliable reference point for the 1st line team on complex escalations
• Work closely with the IT Infrastructure Manager to identify areas for automation, efficiency improvement, and platform development across the team's toolset
• Ensure all work is delivered in line with change management processes, data protection requirements, and IT security policy
