About Medinet & Healthharmonie
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.
Role Purpose
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 Freshservice 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.
Key Responsibilities
Technical Escalation & Team Support
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
Platform Development & Delegated Work
Lead the ongoing development and continuous improvement of the Freshservice ITSM platform - building workflows, automations, forms, SLA rules, and reporting to support the team's operational needs
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
Infrastructure, Cloud & Security
Administer and develop the Microsoft Azure and Microsoft 365 estate - Entra ID, 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
Process & Collaboration
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
Essential Requirements
Demonstrable experience at 3rd line infrastructure level, with a strong track record of resolving complex, multi-system incidents
Deep working knowledge of Microsoft Azure - including Entra ID, Intune, Azure AD, Conditional Access, and Azure Virtual Desktop
Strong Microsoft 365 administration skills - Exchange Online, Teams, SharePoint, OneDrive, and licensing
Solid, hands-on networking experience - TCP/IP, DNS, DHCP, VLANs, firewall rule management, and VPN
Experience developing or administering an ITSM platform - building workflows, automations, forms, and reporting (Freshservice, ServiceNow, or similar)
Comfortable working autonomously on technical problems with minimal direction, and equally comfortable documenting and communicating findings clearly
Strong diagnostic skills and a methodical, structured approach to problem-solving
Ability to explain complex technical concepts clearly to colleagues at varying levels of experience
Desirable / Advantageous
Microsoft AZ-104 (Azure Administrator Associate) or AZ-305 (Azure Solutions Architect Expert)
Microsoft AZ-800 (Administering Windows Server Hybrid Core Infrastructure)
Experience with Freshservice specifically - including workflow automations, API integrations, and custom reporting
PowerShell or other scripting experience for automation of routine infrastructure tasks
Experience with Palo Alto GlobalProtect VPN or similar enterprise firewall platforms
Exposure to healthcare or NHS IT environments
Familiarity with endpoint management at scale using Intune or similar MDM platforms
Experience of mentoring or coaching junior or mid-level engineers (formal or informal)
Our Commitment
This role is designed for a technically exceptional engineer who wants to operate at the cutting edge of a growing infrastructure team - someone who finds as much satisfaction in developing a platform or solving a thorny architectural problem as in resolving a complex incident. You will have genuine autonomy, direct influence on how the team works, and a clear line of sight to the IT Infrastructure Manager. Management responsibility is not part of this role, but you will be a technical anchor for the team and your contribution will be felt across everything the infrastructure function does. We welcome applications from candidates who may not meet every desirable criterion but can demonstrate exceptional technical depth and a genuine drive to develop both themselves and those around them.
Why Join Us?
By joining Medinet Group, you'll become part of the infrastructure that enables outstanding patient care across the UK. Your work will directly support clinicians and operational teams in delivering safe, efficient and effective healthcare services.
In return, we offer:
Medinet Group is proud to be an equal opportunities employer. We celebrate diversity and are committed to creating an inclusive environment for all employees.
