IT Systems & Infrastructure Manager


numi are currently working with a growing, operationally smart business, who are looking for an IT Systems & Infrastructure Manager to take control of their internal tech setup — from infrastructure and systems through to third-party supplier performance, data reporting, and future-facing automation.


This is not a maintenance role. You’ll be hands-on, yes, but also trusted to shape how IT supports the wider business. You’ll manage outsourced IT partners, own security and compliance, and drive improvements using tools like Power BI and AI.


🚀 The role:

  • Lead systems and infrastructure operations (Windows, networks, M365 Business Central, Eque2 Housebuilding)
  • Keep third-party IT suppliers accountable and delivering at pace
  • Maintain and evolve network security (VPNs, firewalls, backups, audits, ISO 27001)
  • Spot inefficiencies — then script or automate them out (PowerShell, Python)
  • Build smarter reporting flows with Power BI, and explore where AI can make an impact
  • Provide occasional desktop support (this is still a hands-on role)
  • Keep documentation clean and clear


👀 What they’re looking for:

  • 1+ year of experience in IT systems/infrastructure
  • Confident managing third-party IT providers
  • Comfortable across Windows OS, VMware/Hyper-V, DNS, DHCP, VPNs
  • Experience with cloud platforms (Azure is a plus)
  • Familiar with monitoring tools and security best practices
  • Proficient in PowerShell or Python for automation
  • Detail-focused, solutions-led, and steady under pressure


🎯 Bonus points if you:

  • Have worked with Business Central or Eque2
  • Know your way around Power BI dashboards
  • Have a strong handle on ISO 27001 and compliance standards
  • Are curious about AI and how it can be practically applied in operations
  • Actually enjoy improving documentation, not just ignoring it


💥 What’s on offer:

  • A high-impact, visible role with real ownership
  • The chance to make decisions, not just execute them
  • Supportive leadership and autonomy to shape systems and tools
  • A growing business with space to scale tech the right way


Interested?

If you’re someone who enjoys fixing problems before they break — and you’re ready to step into a strategic yet hands-on IT lead role — I’d love to tell you more.
