Senior Information Technology Engineer

RED is a global fast paced recruitment company with offices across the US and Europe with our HQ being here in Shoreditch, London.

The Senior IT Engineer is a hands-on, helpdesk-first role requiring strong technical support experience, broad infrastructure knowledge, operational discipline and clear documentation. The successful candidate will combine reliable day-to-day support with proactive monitoring, continuous improvement and defined project delivery, building towards greater responsibility in systems administration and infrastructure engineering.

Below, I have detailed some of the responsibilities of the role and benefits you can receive while working for a successful business like RED:

• Role Purpose and Career Progression - The role is primarily focused on hands‑on 1st and 2nd line helpdesk support, with appropriate 3rd line tasks, routine systems administration and technical project work. It offers a clear progression path into systems administration and wider infrastructure engineering as the individual develops their technical capabilities.
• Helpdesk and Technical Support - Provide day‑to‑day technical support, taking ownership of incidents and service requests from initial investigation through to resolution or documented escalation. Troubleshoot hardware, software, application and connectivity issues methodically, maintain accurate Fresh service tickets and keep users informed throughout.
• User Administration and Lifecycle Management - Manage employee onboarding, offboarding and account changes across Microsoft 365, Entra , Active Directory and business applications. Ensure accounts, licences, permissions, access rights and associated records are accurate, secure and completed on time.
• Hardware and Endpoint Management - Build, configure, deploy, maintain and troubleshoot laptops and other endpoint devices, including managing Intune enrolment, patching and device compliance. Maintain accurate asset records, oversee equipment repairs and replacements, and manage stock, warranties and hardware life cycles.
• Microsoft 365 Administration - Provide routine administration, support and troubleshooting across Exchange Online, Teams, SharePoint, One Drive, Entra , Intune, Defender and Microsoft 365 Apps. Resolve routine issues independently, investigate more complex problems and provide clear technical findings when escalation is required.
• Business Applications and CRM Support - Provide day‑to‑day operational support for Dynamics 365, RED's CRM environment and its wider portfolio of business applications. Manage access and configuration, investigate application and integration issues, work with suppliers where necessary, and maintain clear operational documentation; previous Dynamics 365 experience is desirable rather than essential.
• Server and Virtualisation Management - Support the routine operation, maintenance and monitoring of Windows Server, Active Directory, DNS, DHCP and virtualisation platforms such as VMware vSphere and vCenter. Monitor system health, performance, capacity and alerts, assist with maintenance and virtual machine management, and elevate significant risks or design decisions to senior technical colleagues.
• Networking and Cisco Meraki - Monitor and maintain the company's network environment, including Cisco Meraki equipment, Wi‑Fi, VPN and firewall services. Troubleshoot connectivity issues, support approved configuration changes and routine maintenance, and maintain accurate network documentation while applying strong networking fundamentals.
• Backup, Recovery and Migration - Monitor backup systems, investigate failed jobs, support restore requests and assist with recovery testing to ensure data and services remain protected. Support migrations across Microsoft 365,…
