This is an exciting opportunity to work at the cutting edge of Smart Building applications, IoT, IT/OT convergence to integrate building auto; HVAC, lighting, security and IoT with enterprise IT Systems. This is a hybrid technical and stakeholder-facing role, combining hands-on engineering expertise with project delivery and business engagement skills. You’ll lead network and infrastructure initiatives end-to-end — from understanding user needs and translating them into technical designs, through to deployment, documentation, and optimisation. The ideal candidate will have a strong grounding in network and security technologies, cloud infrastructure, and project management, with the ability to communicate effectively across technical and non-technical teams.
Key Responsibilities Network & Infrastructure Design Design, deploy, and maintain network infrastructure including LAN/WAN, wireless, VPN, and firewalls.

Configure and monitor firewalls, intrusion detection/prevention systems, and endpoint security solutions. Support identity and access management, MFA, and secure network access policies. Conduct regular vulnerability assessments, patch management, and system hardening. Project Management & Delivery Lead infrastructure and network projects from scoping through delivery, ensuring quality, cost, and time objectives are met. Define technical requirements and translate business needs into deliverable solutions. Develop and maintain project documentation including architecture diagrams, risk registers, and deployment guides. Manage vendors, suppliers, and third-party contractors to ensure aligned delivery outcomes. Apply structured project management methodologies (Agile, Prince2, or hybrid). Stakeholder Engagement & Collaboration Act as a trusted advisor to internal teams and business units, gathering and translating technical requirements into actionable solutions. Collaborate closely with IT, Operations, Security, and external partners to ensure seamless integration and delivery. Communicate complex technical concepts in clear, non-technical language for diverse audiences. Provide updates and reports on project progress, risks, and mitigations to leadership and stakeholders. Operations & Support Provide third-line support for network and infrastructure incidents and escalations. Monitor system performance and implement improvements to enhance reliability and scalability. Maintain detailed documentation of infrastructure, configurations, and changes. Participate in an on-call or escalation rota as required.
Qualifications & Experience Essential: 5+ years’ experience in network and infrastructure engineering roles. Proven experience managing and delivering technical projects end-to-end. Strong knowledge of IP networking, routing, switching, VLANs, VPNs, and firewall configuration (Cisco, Fortinet, Palo Alto, etc.). Hands-on experience with cloud platforms (Microsoft Azure, AWS, or equivalent). Familiarity with Active Directory, Azure AD, DNS, DHCP, Group Policy, and M365 environments. Strong understanding of cybersecurity principles, access control, and encryption standards. Excellent communication, stakeholder engagement, and documentation skills. Desirable: Relevant certifications (CCNA, CCNP, CompTIA Network+/Security+, Azure Administrator, etc.). Experience with infrastructure automation or scripting (PowerShell, Python). Knowledge of monitoring and observability tools (SolarWinds, PRTG, Grafana, etc.). Experience with ITIL practices and ServiceNow or equivalent ticketing systems.
Personal Attributes Technically curious, proactive, and solutions oriented. Confident engaging with technical and business stakeholders alike. Comfortable balancing hands-on technical work with structured project delivery. Strong organisational and time-management skills with a focus on quality and outcomes.
