Principle Network Architect

Key Responsibilities

? Own the network architecture standards and Building Block topology framework for the physical

security estate, setting the designs the senior team builds against.

? Define perimeter-resilience and high-availability strategy, including ERPS / MSTP ring architecture

standards and cable-cut survivability requirements for critical zones.

? Establish network security and configuration standards, and the zero-touch-config automation strategy

that governs deployment at scale.

? Set monitoring, inventory and observability standards (NetBox, SolarWinds, PRTG, Syslog) for the

network estate.

? Own network hardware and firmware lifecycle strategy, EOL evaluation, refresh planning and vendor

selection across Cisco / Juniper / Arista.

? Serve as the final escalation point for the most complex network incidents and architectural decisions.

? Partner with the Infrastructure Engineering team and program leadership to align network architecture

with shared security boundaries, governance, SLAs and KPIs.

? Author and approve network architecture standards, design documentation and runbooks; drive

continuous improvement of resilience and security posture.

? Mentor and develop senior network engineers, establishing best practices and building long-term

network engineering capability.

Required Skills

? 10+ years of enterprise network engineering, including architecture leadership and standards

ownership in large or critical environments.

? Authoritative enterprise network design across Cisco / Juniper / Arista, with deep routing, switching

and segmentation expertise.

? Mastery of ERPS / MSTP ring protocols and high-availability perimeter design, including

survivability strategy for critical zones.

? Strong network automation and zero-touch-config leadership (Python / Ansible) and standards

definition.

? Monitoring and inventory architecture (NetBox, SolarWinds, PRTG, Syslog); hardware / firmware

lifecycle and vendor management.

? Demonstrated network architecture leadership — standards ownership, cross-functional partnership,

mentoring and escalation leadership.

? Certifications — Required: Cisco CCNP or Juniper JNCIS. Strongly preferred: CCIE or equivalent

architect-level credential; network automation (Python / Ansible); ERPS / MSTP design; ITIL 4.

Tools Required

? Standards & Access: 802.1X, VLAN segmentation, DNS, DHCP for secure network access and

segmentation.

? High-Availability Architecture: ERPS and MSTP ring topologies for perimeter resilience and cable-

cut survivability.

? Automation: zero-touch-config and scripting (Python / Ansible) for standardized, rapid deployment.

? Monitoring & Vendors: NetBox, SolarWinds, PRTG and Syslog analysis; Cisco / Juniper / Arista

platforms; hardware / firmware EOL refresh.
