Full job description

Role Overview

We are seeking a highly skilled IT Infrastructure & Support Technician to take ownership of the configuration, validation and optimisation of integrated IP-based security systems prior to deployment.

This is not a standard equipment pre-build role. You will be responsible for architecting, configuring, hardening and performance-testing CCTV, Access Control, Intruder and Intercom systems within a controlled pre-build environment — ensuring they are secure, scalable and deployment-ready.

Alongside security systems engineering, you will play a key role in managing and improving our internal IT infrastructure, supporting hybrid cloud environments, virtualised systems and network architecture.

This position suits someone who is equally comfortable configuring VLANs and firewalls as they are commissioning VMS platforms and troubleshooting SIP-based intercom systems.

Core Responsibilities

Security Systems Engineering (Pre-Build & Validation)

Pre-Build configuration of IP-based CCTV, Access Control, Intruder and Intercom platforms prior to deployment by our in house engineers.
Configure network topology including VLAN segmentation, firewall rules, routing, NAT and VPN access
Implement secure remote access solutions and hardened configurations
Validate firmware, patch levels and cybersecurity posture prior to site deployment
Test system resilience, redundancy, failover and storage performance
Pre-stage cloud-connected security platforms and hybrid integrations
Produce configuration documentation, network diagrams and deployment packs
Evaluate and benchmark new hardware, VMS platforms and access control technologies
Provide Tier 3 technical escalation support to field engineers

IT Infrastructure & Systems Administration

Administer and optimise internal infrastructure (Windows Server, Active Directory, DNS, DHCP, Group Policy)
Manage Microsoft 365 tenant including SharePoint, Exchange Online, conditional access and security policies
Support hybrid identity (on-prem AD + Azure AD / Entra ID)
Maintain and optimise virtualised environments (VMware / Hyper-V)
Manage backup solutions, disaster recovery strategy and business continuity planning
Maintain core network infrastructure (Layer 2/3 switching, VLANs, trunking, firewall policy, VPN, SD-WAN where applicable)
Oversee endpoint provisioning, MDM policies, and lifecycle management
Implement cybersecurity best practices including MFA, least-privilege access, system hardening and vulnerability remediation
Lead internal IT improvement projects from design to deployment

Digital & Technical Systems Support

Administer internal helpdesk and documentation systems
Provide 2nd and 3rd line technical support to engineers and key customers
Assist with website infrastructure and hosting environments
Manage and optimise company digital platforms and social channels

Technical Skills & Experience

Essential

Strong understanding of TCP/IP networking, routing, switching and VLAN segmentation
Experience configuring firewalls and secure remote access (VPN, port forwarding, NAT policies)
Advanced Windows administration experience
Experience managing Microsoft 365 / hybrid environments
Good knowledge of VOIP telephony systems
Virtualisation experience (VMware or Hyper-V)
Strong troubleshooting methodology across network, system and application layers
Understanding of cybersecurity principles and secure system design

Highly Desirable

Experience with Enterprise level IP-based CCTV, Access Control & Intercom Systems
Knowledge of ONVIF, SIP, RTSP and related protocols
Experience with PowerShell scripting and task automation
Familiarity with backup & disaster recovery solutions
Experience within the electronic security integration sector

Personal Profile

Analytical and methodical in approach
Strong documentation discipline
Comfortable working at both architectural and hands-on levels
Proactive and solutions-driven
Able to manage multiple technical streams simultaneously

Why This Role Stands Out

Genuine technical ownership of pre-deployment security builds
Influence over infrastructure standards and cybersecurity posture
Exposure to emerging IP security and hybrid cloud technologies
Opportunity to shape internal IT strategy

Job Type: Full-time

Pay: £32,000.00-£38,000.00 per year

Benefits:

Company pension
Cycle to work scheme
On-site parking
