Our purpose at Gallagher is ‘Protect what matters most’ — and we live it every day. Whether that’s protecting some of the world’s most secure environments or supporting agricultural businesses, we care deeply about our people, their families, and our wider communities.
Gallagher Security is on a mission to unlock more value for our customers through the power of our people and solutions. Our culture is entrepreneurial, fast-paced, and constantly evolving — with opportunities to connect and build your career globally.
We’re painting the future of what’s possible. Come join us.
This is not your typical service desk role.
Based in our UK office, you’ll be the go-to IT expert on-site, supporting our Security business and acting as the face of IS locally. You’ll work independently day-to-day, while staying connected to a global IS team who have your back when you need it.
It’s a hands-on, people-focused role where you’ll balance technical troubleshooting with building strong relationships - keeping systems running and ensuring a great experience for users.
If you’re someone who enjoys ownership, variety, and being genuinely relied on, this role offers real scope to make an impact.
Provide Level 1–2 support across desktops, laptops, mobile devices, and core business systems
Manage incidents and service requests end-to-end using ITSM tools, ensuring timely resolution against SLAs
Build, configure, and maintain user devices, accounts, and access across the environment
Troubleshoot networking, telephony, and meeting room technology issues
Act as the primary IS contact for the UK office, supporting users and onboarding new starters
You’ll also work closely with global IS teams on escalations, contribute to continuous improvement, and help enhance how IT support is delivered across the business.
We’re looking for someone who enjoys working autonomously, takes ownership, and takes pride in delivering a great support experience.
You’ll be confident troubleshooting technical issues, but just as comfortable explaining them in a clear and user-friendly way.
What you’ll bring:
3–5+ years’ experience in IT Service Desk or End User Support
Strong troubleshooting skills across Windows environments and business applications
Experience with Microsoft 365 and user/device administration
Familiarity with ITSM tools and working to SLAs
Solid understanding of networking fundamentals (Wi-Fi, VPN, TCP/IP)
A proactive, organised approach with strong communication skills
Nice to have:
Experience in a sole-charge or highly autonomous IT support role
Exposure to endpoint management tools (e.g. Intune, SCCM) or cloud platforms like Azure
Experience supporting telephony, AV, or conferencing technologies
At Gallagher, we’re proud of our people-first culture. You’ll be trusted to own your space, supported by a global team, and given the opportunity to grow your technical capability while making a real impact locally.
This role is based on-site in the UK, where you’ll play an important role supporting a close-knit team and keeping the business running smoothly.
We offer:
Competitive salary and bonus opportunities
A supportive, collaborative team environment
Opportunities to grow your career within a global organisation
Social activities, team events, and wellbeing initiatives
If you’re looking for a role where you can own the environment, build strong relationships, and deliver great IT support, we’d love to hear from you.
Whilst we are pretty keen to get this role filled, we know it's crucial we find the right fit for our organisation, so this advert will remain open until we've nailed that brief. If this sounds like a bit of you then we'd love to hear from you.
