About Role

This role is not vendor-specific and will involve working with multiple technologies and manufacturers, including Cisco, HPE/Aruba, and Ruckus. You will be responsible for configuring, installing, and supporting network infrastructure, ensuring secure, resilient, and high-performing network environments for our clients.

You will work closely with Design, Sales, and Project teams, supporting the full life cycle from tender review and technical design through to installation, testing, client handover, and ongoing support.

  • Modify and manage firewall rules and network security configurations, alongside monitoring and addressing security vulnerabilities.
  • Design and deploy servers in both physical and virtual environments, including file structures, permissions, and access controls.
  • Provide technical support for workstations, operating systems, and applications, helping to minimise downtime for users.
  • Produce low-level design documentation and technical specifications, calculating and defining configurations across network hardware.
  • Install and commission hardware on client sites in line with approved designs, managing installations from start to finish.
  • Build and install temporary wall- and floor-mounted cabinets where required.
  • Review tender documentation and support design development, ensuring solutions meet technical and compliance requirements.
  • Build bills of materials, including engineering time estimates, to support accurate costing and proposals.
  • Collaborate with internal teams and technology partners on extended solutions such as voice and in-building cellular systems.
  • Carry out final testing, commissioning, and handover, including end-user training for client support teams.
  • Explain technical concepts clearly to non-technical stakeholders.
  • Provide ongoing support and maintenance, including firmware updates, security patches, and break-fix support.
  • Carry out pre- and post-installation wireless surveys using industry-standard tools to validate performance and coverage.
