IT Systems Lead

Our client is looking for an IT Systems Lead to take full technical ownership of their IT estate in North Somerset.

You'll need hands-on experience across Microsoft 365, Azure, and network infrastructure, with a solid grounding in cyber security frameworks.

This is a key hire for a growing R&D and engineering business for their internal systems.

The Key Responsibilities of a IT Systems Cyber and Infrastructure Lead:

• Take full technical ownership of all IT systems, infrastructure, and platforms across the business.
• Embed cyber security into system configuration, access control, and integration — aligned to CE+, IASME, ISO27001, and CSM.
• Own and manage the Fortinet-based network infrastructure including firewalls, switching, VPN, and failover.
• Manage the Azure environment and Microsoft 365 E5 estate, including identity, device management, and conditional access.
• Define and enforce access control standards, privileged access models, and device configuration policies.
• Line manage and develop the IT Technician/Apprentice, building internal capability through documentation and knowledge sharing.
• Maintain accurate, up-to-date documentation of all systems, infrastructure, and environment architecture.
• Report to the IT Controller and Board on system status, risks, and improvement priorities.

Below is a list of Key Skills required for a IT Systems Cyber and Infrastructure Lead, however you will not be expected to have everything:

• Senior-level hands-on experience across IT infrastructure, systems, and networking in a technical organisation.
• Strong working knowledge of Microsoft 365 E5, including identity, endpoint management, and conditional access.
• Experience managing Azure cloud environments with a structured approach to access, policy, and connectivity.
• Hands-on experience with Fortinet network infrastructure including firewalls, switching, and VPN.
• Practical knowledge of cyber security frameworks including Cyber Essentials Plus, IASME, and ISO27001-aligned practices.
• Ability to define and maintain identity and access models, privileged access controls, and device configuration standards.
• Experience producing clear technical documentation for systems, infrastructure, and network architecture.
• Comfortable working across both corporate and project/development IT environments with appropriate separation and control.

The client would also like to see some of the below, but this is not essential:

• Experience working with or supporting Windows and Linux-based development environments.
• Familiarity with the UK Government Cyber Security Model (CSM).
• Exposure to AI/ML or high-performance computing environments and their integration into wider IT estates.
• A recognised cyber security certification such as CISSP, CompTIA Security+, or equivalent.
• Bachelor's degree or equivalent in IT, Computer Science, or a related discipline.
• Experience in an SME or R&D-focused technical organisation where you've had to wear multiple hats.
