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.
