Job description

About Us

We are a growing UK-based retail business with a large multi-site estate spanning stores, Head Office and operational locations.

Job Description

We are looking for a hands-on Infrastructure Engineer to support the day-to-day operation of our IT infrastructure across a multi-site retail environment.

You will work across networking, Microsoft technologies, virtualisation, POS and wider infrastructure, while acting as a key point of escalation for more complex technical issues.

A significant part of the role will involve supporting new store openings, refurbishments and infrastructure rollouts, working closely with internal teams, stores and third-party suppliers to ensure technology is ready for operational launch.

This is not a management position. We are looking for someone who enjoys getting into the detail, solving problems and taking ownership from diagnosis through to resolution.

Key Responsibilities

• Maintain and support IT infrastructure across stores, Head Office and wider operational locations.
• Troubleshoot infrastructure, networking, connectivity, server and endpoint issues.
• Support retail technology including POS/EPOS, tills, payment devices and store systems.
• Assist with the technical delivery and readiness of new store openings, refurbishments and relocations.
• Work with networking technologies including firewalls, switching, Wi-Fi, VPN and site connectivity.
• Support Microsoft environments including Microsoft 365, Active Directory/Entra ID and Windows Server.
• Provide support across virtualised environments including VMware and/or Hyper-V.
• Act as an escalation point for complex incidents and recurring infrastructure problems.
• Coordinate with third-party suppliers, vendors, ISPs and field engineers where required.
• Contribute to infrastructure improvements, technical documentation and operational processes.
• Participate in a light out-of-hours/on-call rota for critical infrastructure incidents.
• Travel occasionally to stores when required, particularly around new openings and infrastructure projects.

Requirements

• 2-5 years' experience in hands-on IT infrastructure or systems support.
• Experience working within a retail, multi-site or geographically distributed environment.
• Strong understanding of networking, including LAN/WAN, VPN, switching and Wi-Fi.
• Experience with Fortinet/FortiGate, Meraki or comparable firewall/networking technologies.
• Working knowledge of VMware and/or Hyper-V.
• Experience supporting Windows Server, Active Directory/Entra ID and Microsoft 365.
• Exposure to POS/EPOS or other retail technology would be highly advantageous.
• Experience supporting infrastructure projects, deployments or new site/store openings.
• Strong troubleshooting and root-cause analysis skills.Comfortable working with vendors, technical teams and non-technical stakeholders.
• A hands-on and proactive approach, with a willingness to take ownership rather than simply escalating problems.
• Ability to think on your feet and remain calm when dealing with operationally critical issues.
• Adaptable, open-minded and collaborative, with the ability to integrate into an established team.

Benefits

• Competitive salary of up to £45,000, depending on experience.
• Hybrid working - 4 days in the London office and 1 day from home.
• Additional compensation for participation in the on-call rota.
• Opportunity to work across a large-scale, multi-site retail technology environment.
• Exposure to infrastructure projects supporting business growth and new site openings.
• Opportunity to develop your technical skills across networking, cloud, virtualisation and retail technology.
• Supportive and established IT team with opportunities for progression.
