Salary: £32,000 - £35,000

Location: Portsmouth (office-based)

Time Off: 43 days annual leave (seriously)

Pension: 26% employer contribution

Progression: Clear route into the infrastructure and projects team - perfect for long-term career growth

Variety: BAU 3rd line support with opportunities to support ad hoc improvement projects

What you’ll be doing:

Acting as the escalation point for 2nd line - owning and resolving complex technical issues.

Working closely with internal users and the wider IT team to keep everything running smoothly.

Contributing to small infrastructure or improvement projects where needed.

A self-starter who takes ownership of problems and sees them through.

Great communication skills, calm under pressure and clear with users.

Someone who’s ready to grow, you want to move towards projects and infrastructure over time.

This isn’t a dead-end support role.

It’s a genuinely rare opportunity to join a team that will back you, give you the time and support to build your skills and open the door to that next step when you're ready.
