You will be joining an established, collaborative group of four engineers (1 Staff Engineer, 1 Senior Network Engineer, 1 Dedicated Wireless/RF Engineer, and 1 Network Engineer). <br><br>In this role, you will be a pillar for our core routing, switching, WAN/backbone transport, multi-cloud interconnects, and edge security systems. Rather than building automation frameworks from scratch, you will partner closely with our dedicated Senior Network Automation Engineer to identify programmatic bottlenecks, standardize configurations, and integrate our multi-vendor ecosystem into our automation pipelines. <br><br>You will be instrumental in consulting directly with internal business lines—spanning hardware engineering, software development, advanced manufacturing, and flight-test operations—to translate unconventional technical constraints into robust, secure, and multi-tenant network designs. Additionally, you will own the delivery of high-capacity carrier transport (wave circuits, dark fiber), provision multi-cloud networking (AWS, Azure, GCP), elevate operational observability, mentor junior engineers, and serve as an escalation point for complex Tier-3 network issues.</p> <h3><strong>WHAT YOU’LL DO</strong></h3> <ul> <li>Design, scale, and maintain resilient campus, datacenter, and field-test networks utilizing both traditional three-tier and EVPN-VXLAN fabric designs across Arista (EOS) and Cisco (Catalyst/Nexus) platforms.</li> <li>Architect, scale, and maintain our corporate and datacenter WAN backbone—owning carrier circuit delivery, capacity planning, and turn-up for optical waves, dark fiber, and DIA across colocation and telecom providers.</li> <li>Design, provision, and maintain resilient hybrid-cloud transit networks across AWS, Azure, and GCP. Implement and manage dedicated interconnects (AWS Direct Connect, Azure ExpressRoute, Google Cloud Interconnect), Transit Gateways/VNet Hubs, dynamic BGP peering, and cloud-native routing architectures.</li> <li>Develop scalable network standards, reference architectures, and implementation patterns.</li> <li>Participate in architecture reviews and provide technical direction for complex network initiatives.</li> <li>Partner with our Senior Network Automation Engineer to drive Network-as-Code workflows—leveraging your foundational knowledge of Python, Nornir, and Jinja2 to define data models, draft templates, and shape API integrations.</li> <li>Partner with our dedicated Wireless/RF Engineer to design, deploy, and maintain robust campus-wide and field Wi-Fi deployments leveraging Aruba and Juniper Mist platforms, focusing on enterprise 802.1X/EAP-TLS authentication and client performance optimization.</li> <li>Implement, audit, and manage Layer 3–7 security policies, microsegmentation strategies, and site-to-site IPsec tunnels utilizing Palo Alto Networks NGFWs mana
