Our integrated businesses - Medinet (insourcing), HealthHarmonie (community specialist services), and HealthHarmonie Minds (mental health and wellbeing services) - work collaboratively with NHS and healthcare partners to improve patient access, reduce waiting times, and drive innovation in healthcare delivery.

Role Purpose

To provide 2nd line infrastructure support and project delivery across the Medinet and Healthharmonie estate. Working as a peer alongside the existing infrastructure team, you will handle escalated tickets from the 1st line team, own defined areas of infrastructure responsibility, and contribute to ongoing projects. Complex technical escalations beyond 2nd line scope are handled by the Lead Infrastructure & Systems Engineer. As the team grows, you will play a key role in ensuring the estate remains well managed, well documented, and resilient.

Key Responsibilities

• Resolve escalated tickets referred from the 1st line support team, taking ownership through to resolution and escalating to the Lead Infrastructure & Systems Engineer where required

• Contribute to infrastructure projects including new site setups, hardware refresh programmes, and cloud migrations
• Provide technical guidance and knowledge transfer to the 1st line support team, supporting their development
• Participate in root-cause analysis for recurring or systemic incidents and implement lasting fixes
• Maintain accurate infrastructure documentation including network diagrams, configuration records, and runbooks
• Assist with security monitoring, patch management, and vulnerability remediation across the estate
• Ensure all work is carried out in line with change management processes, data protection requirements, and IT security policy

Essential Requirements

• Demonstrable experience in a 2nd line infrastructure support role
• Strong working knowledge of Microsoft Azure - including Entra ID, Intune, Azure AD, and Azure Virtual Desktop
• Experience administering Microsoft 365 - Exchange Online, Teams, SharePoint, OneDrive, and licensing
• Solid networking knowledge - TCP/IP, DNS, DHCP, VLANs, firewalls, and VPN
• Experience with Windows Server administration
• Ability to work independently, managing priorities effectively across concurrent incidents and projects
• Strong analytical and diagnostic skills with a methodical approach to fault resolution
• Clear written and verbal communication - able to explain technical issues to non-technical colleagues and stakeholders

Desirable / Advantageous

• Microsoft AZ-104 (Azure Administrator Associate) or AZ-800 (Administering Windows Server Hybrid Core Infrastructure)
• Experience with Palo Alto GlobalProtect VPN or similar enterprise firewall platforms
• Familiarity with endpoint management tools such as Intune or SCCM
• Experience supporting a multi-site organisation
• Exposure to healthcare or NHS IT environments
• Experience with ITSM platforms such as Freshservice or ServiceNow
• PowerShell scripting experience for automation of routine infrastructure tasks

Our Commitment

This role suits someone who enjoys the variety of a busy infrastructure environment, comfortable moving between a complex escalation, a project task, and a knowledge-share with a junior colleague in the same day. The team is small, technically capable, and collaborative. You will have real ownership of your area from day one, with direct access to senior technical expertise through the Lead Infrastructure & Systems Engineer and the IT Infrastructure Manager. We welcome applications from candidates who may not meet every desirable criterion but can demonstrate strong technical ability and a genuine commitment to continued learning and development.
