Network Security Architect

This position puts you in charge of how a hybrid enterprise network is secured end to end - from the links that join the data center to the cloud, through the firewalls that police traffic, down to the segmentation and name-resolution layers underneath. The work is architectural and hands-on in equal measure.

Day-to-Day Scope

Design Work

• Draw up network security architectures that satisfy internal policy and regulatory obligations without slowing delivery
• Map out the private networking layer: virtual networks, subnet layouts, and where segmentation boundaries belong
• Set the Domain Name System (DNS) approach so resolution stays trustworthy and traffic lands where it should

Implementation & Upkeep

• Establish and run connectivity spanning on-premises infrastructure and cloud platforms
• Dial in routing protocols and traffic paths so performance holds and failover works when a circuit drops
• Stand up, tune, and support Palo Alto Networks and Microsoft Azure Firewall deployments for threat defense

Working With Others

• Sit with teams outside networking and convert what the business needs into an architecture that actually holds up
• Serve as the senior technical voice for the network engineering group, mentoring engineers as you go

Essentials

• At least 5+ years spent architecting network security at enterprise scale
• Connectivity: demonstrated skill joining on-premises environments to cloud securely - Virtual Private Network (VPN) tunnels, Microsoft Azure ExpressRoute, and broader hybrid interconnect patterns
• Routing: deep working knowledge of Border Gateway Protocol (BGP) and Open Shortest Path First (OSPF), plus route optimization and multi-path design
• Firewalls: real configuration, operations, and troubleshooting time on Palo Alto Networks firewalls and Azure Firewall
• Domain Name System (DNS): solid footing in DNS architecture, Domain Name System Security Extensions (DNSSEC), filtering, and DNS-driven threat prevention
• Private Networking: experience delivering private network designs, segmentation strategies, and zero-trust network architectures

A Plus

• Network security certification - Certified Information Systems Security Professional (CISSP), Certified Ethical Hacker (CEH), or comparable
