Youre a confident and experienced Network Architect with a proven ability to lead from concept to delivery. You can articulate design decisions, anticipate challenges in critical environments, and manage stakeholder expectations with ease.

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.
