My client is seeking a talented and experienced Network Solutions Architect to join their high-performing Network Services team, delivering on the prestigious Emergency Services Network (ESN) programme.

Resilient backhaul and encryption
Support for MCX (Mission Critical Services) across mobile and fixed-line networks

Essential Experience:

Proven experience architecting and delivering solutions in Emergency Services, Blue Light, Public Sector, or mission-critical environments.
Deep technical understanding of WAN, LAN, SD-WAN, Wi-Fi, and secure cloud connectivity, with real-world experience in design and implementation.
Familiarity with ESN architecture, including knowledge of Airwave, 3GPP MCX services, and E2E Quality of Service models.
Experience designing network integration with public mobile networks and understanding of private APN routing, VPNs, firewall policies, and multi-zone DMZs.
Strong knowledge of Cisco, Fortinet, Palo Alto, Juniper, or similar platforms.
Experience with network configuration, PoC testing, integration validation, and security accreditation processes.
Exceptional customer-facing skills and ability to communicate technical concepts clearly to both technical and non-technical stakeholders.

Due to the sensitive nature of the work, you must be eligible to obtain Security Clearance (SC)
