We're hiring an L3 Infrastructure Engineer to join a growing IT services provider supporting a wide range of SMB customers across Ireland. This is a varied role blending hands-on IT support, project implementation, and technical leadership, with exposure to a broad technology stack.

You'll be working across everything from firewalls and servers to Microsoft 365 & Azure cloud platforms, leading projects and providing L3 support while occasionally visiting customer sites.

What You'll Be Doing
  • Acting as technical lead on infrastructure projects (server builds, firewalling, installs)
  • Supporting SMB customers with day-to-day IT needs – from password resets to project rollouts
  • Installing kit, pulling cables, and setting up on-prem and cloud environments
  • Working with a wide range of vendors – HP, Dell, Cisco, Checkpoint
  • Balancing office, home, and customer site work as needed
What You'll Bring
  • Strong technical background across Microsoft 365 & Azure
  • Hands-on experience with firewalls (SonicWall preferred), Unifi, and server builds
  • Broad knowledge of enterprise kit (HP, Dell, Cisco, Checkpoint)
  • Comfortable juggling L3 support and project delivery in customer-facing environments
  • Driving licence and vehicle (essential for occasional customer site visits)
  • Certifications are a bonus but not essential – attitude and capability matter most
The Setup
  • Hybrid working: 3 days in the Dublin office (Tues–Thurs), 2 days WFH
  • Occasional site visits to customers (expenses covered)
  • Collaborative team with opportunities to take on technical leadership
The Package
  • Benefits package aligned with career growth and certification support
  • Flexibility, variety, and the chance to lead projects end-to-end

If you're a senior infrastructure engineer with a get-up-and-go attitude and want to combine technical depth with project leadership, this role is for you.

Apply today and step into a position with variety, ownership, and growth.
