Job description

Frimly | Hybrid working 2/3 days onsite

We are supporting a specialist technology and defence organisation delivering complex, high-trust infrastructure solutions in demanding environments. This is a design-led role, not a maintenance position. We need someone who can design, implement, and see infrastructure through build, commissioning, and acceptance.

The business operates at scale across digital, cyber, intelligence, and mission-critical environments. You will work on technically integrated solutions where accuracy, coordination, and delivery discipline matter.

• Design technical infrastructure to support the full solution.
• Produce supporting designs for LLD and associated configuration.
• Lead build, commissioning, and acceptance activity.
• Deliver coherent, technically integrated solutions against requirements.
• Manage Bill of Materials and project-schedule delivery.
• Supervise installation and commissioning, including subcontractors.
• Update technical specifications and track approved changes.
• Work with stakeholders on infrastructure design decisions.
• Strong campus networking experience with design, build, and configuration.
• Solid understanding of IP networking, DNS, routing, VPN, and firewalls.
• Experience with network design and domain control, including AD, DNS, and NPS.
• Exposure to virtual servers and networking, including VMware or Proxmox.
• Ability to analyse existing designs and translate requirements into delivery.
• Comfortable working with physical hardware, rack build, and troubleshooting.

This is a strong opportunity for an infrastructure engineer who wants ownership of full-life-cycle delivery, not BAU support. The package is competitive, with hybrid working and work that carries genuine technical depth.
