Gosport - Fully On-Site

33,000 - 34,500 per annum

We’re partnered with a growing logistics client in Gosport who is investing heavily in their IT landscape and we’re on the hunt for a hands-on, technically solid 2nd Line Infrastructure Engineer to be a key part of that journey.

If you’re someone who enjoys getting into the detail, troubleshooting the root cause of issues, and being part of a supportive, collaborative team, this is a role worth considering.

This is a fully office-based role (no hybrid), working in a close-knit environment where the team genuinely helps each other out and celebrates wins together. As the company expands into Europe, there are exciting changes on the horizon and you’ll have the chance to help shape the future of their IT infrastructure.

What You’ll Be Doing

Acting as a key 2nd line escalation point for infrastructure and user issues

Investigating issues down to root cause, not just applying quick fixes

Supporting and maintaining both on-prem infrastructure and Azure cloud environments

Managing network configurations - TCP/IP, DNS, DHCP, VLANs, VPNs

Using tools like command prompt, PowerShell, and performing domain registry checks

Supporting Windows Server, Active Directory, Group Policy, and Office 365

Working on small to mid-size projects and contributing to wider infrastructure planning

Ensuring systems are compliant and secure

What You’ll Need

Strong experience in a 2nd line or similar support role

Comfortable working across on-prem and Azure infrastructure

Confident with networking (routing, switching, firewalls, VPNs, VLANs)

Knowledge of Windows Server, Active Directory, Group Policy

Experience with desktop environments (Windows 10/11, Office 365)

Familiar with command line tools, scripting basics (PowerShell), and domain tools

A proactive mindset - someone who wants to fix the root of the problem, not the symptom

Flexible and collaborative - happy to help where needed, not stuck in silos

Nice to Have

Azure or AWS certification

PowerShell scripting

Linux experience

ITIL awareness

Experience in logistics or warehousing environments

Why This Role Stands Out

Growth: This is a company on the up - with major plans to expand across Europe

Innovation: Significant investment going into IT - be part of shaping the roadmap

Team Culture: A strong, tight-knit IT team that supports one another

Variety: Hands-on technical work across both traditional and modern platforms

Development: Chance to grow with the business and expand your technical scope
