What You’ll Be Doing:

As a Senior 3rd Line Infrastructure Engineer, you are the technical engine of the Technical Account Management team. This is not a standard "reactive" 3rd line role; while you will handle deep-level escalations, your primary focus is proactive infrastructure health and the delivery of technical projects. You will work closely with the Team Lead to ensure clients' infrastructure is aligned with best practices and modern standards. This is a hands-on role where you will design and implement a range of IT change projects for clients in your region. You will develop and maintain relationships that clients put trust in to deliver the solutions that their organisations need, while providing expertise‑in‑depth to the Service Team who escalate faults to you for resolution.

Key Responsibilities of the Senior 3rd Line Infrastructure Engineer:

  • Infrastructure Projects: Own and execute technical projects such as server migrations, Microsoft 365 tenant-to-tenant migrations, and network refreshes.
  • Technical Alignment: Conduct regular technical reviews of client environments to identify risks, end-of-life hardware/software, and security gaps.
  • 3rd Line Support: Act as a senior escalation point for the Service Desk, resolving complex issues across virtualization, storage, and cloud platforms.
  • Documentation: Maintain high-quality technical documentation and "Site Files" for client environments to ensure seamless support across the business.
  • Client Advisory: Support the Team Lead in technical meetings by providing data-driven insights on system performance and required upgrades.

Experience & Qualifications:

  • Minimum 3-5 years in a technical role, ideally within an MSP or a multi-site internal environment.
  • Proven ability to follow a project plan, meet milestones, and communicate progress clearly.
  • Based within a commutable distance of Bedford (for site visits and office collaboration).
  • Ideally holding recognisable vendor qualifications.
  • Infrastructure: Expert knowledge of Windows Server (2019 onward), Active Directory/GPO, and Entra/Microsoft 365/Exchange Online.
  • Virtualisation: Advanced experience with VMware vSphere or Microsoft Hyper-V.
  • Cloud: Proven experience in Azure or AWS (migrations, environment builds, and security).
  • Networking: Strong understanding of wired networking, experience with firewalls (Sophos/Fortinet/Cisco), and VPNs.
  • Wireless Networking: Experience with planning, deployment and surveying of wireless networks in commercial, education and/or healthcare settings with vendors like Meraki/Aruba/Ruckus.
  • Backup & DR: Management of enterprise-level backup solutions (Veeam, Redstor, etc.).

What’s in It for You?

  • £35,000 - £38,000 based on experience
  • 22 days annual leave
  • A friendly, collaborative office culture
  • Real variety every day is different
  • Opportunities for professional development
  • Avoid the city centre traffic!
  • Be part of a team where your ideas and input genuinely matter
