Senior Network Engineer

We are seeking a Senior Network Infrastructure Engineer to join our Core Network Engineering team. 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).

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.

You will be instrumental in consulting directly with internal business linesspanning hardware engineering software development advanced manufacturing and flight-test operationsto 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.

• 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.
• Architect scale and maintain our corporate and datacenter WAN backboneowning carrier circuit delivery capacity planning and turn-up for optical waves dark fiber and DIA across colocation and telecom providers.
• 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.
• Develop scalable network standards reference architectures and implementation patterns.
• Participate in architecture reviews and provide technical direction for complex network initiatives.
• Partner with our Senior Network Automation Engineer to drive Network-as-Code workflowsleveraging your foundational knowledge of Python Nornir and Jinja2 to define data models draft templates and shape API integrations.
• 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.
• Implement audit and manage Layer 37 security policies microsegmentation strategies and site-to-site IPsec tunnels utilizing Palo Alto Networks NGFWs managed globally via Panorama.
• Elevate our telemetry stack beyond traditional SNMP polling. Implement deep-visibility tooling flow analysis and streaming telemetry dashboards (Grafana Prometheus Syslog) to proactively detect degradation reduce MTTR and improve alerting fidelity.
• Act as a final point of technical escalation for critical intermittent or high-blast-radius network anomalies. Lead rigorous post-mortem reviews and participate in a shared multi-engineer Tier-3 on-call rotation.
• Actively support coach and level-up junior systems administrators and network engineers across the broader IT and Infrastructure organizations through runbook authoring architectural reviews and pairing sessions.

• 8 years of hands-on experience designing scaling and maintaining complex multi-vendor enterprise backbone and campus production networks.
• Advanced Routing Switching & Multi-Tenancy:
• Deep operational mastery of BGP (path selection community manipulation convergence optimization) and OSPF.
• Demonstrated production experience deploying and troubleshooting EVPN-VXLAN fabrics.
• Proven experience designing multi-tenant network architectures (VRFs dynamic segmentation macro- and micro-segmentation).
• Expert-level packet analysis skills (tcpdump Wireshark) for diagnosing subtle transit failures MTU/fragmentation mismatches and asymmetric routing.
• Experience working directly with carriers and telecom providers to scope order cross-connect turn up and test high-bandwidth transport circuits (10G/100G Waves dark fiber DIAs).
• Proven track record provisioning and troubleshooting cloud-native networking components and dedicated connectivity (AWS Direct Connect Azure ExpressRoute GCP Cloud Interconnect VPC/VNet peering Transit Gateways).
• Automation Fluency & Collaboration:
• A strong programmatic mindset with the ability to read review and write foundational Python.
• Working familiarity with automation ecosystems (Nornir Jinja2 Netmiko) and REST APIs sufficient to collaborate effectively with dedicated automation software engineers.
• Comfort with Git workflows for managing configuration versions and operational changes.
• Multi-Vendor Hardware Mastery: Expert-level configuration architecture and troubleshooting experience across:
• Arista Networks: EOS CloudVision (CVP) modern spine-and-leaf designs.
• Cisco Systems: Catalyst 9k series (IOS-XE) and Nexus switches (NX-OS).
• Palo Alto Networks: NGFW appliances Panorama App-ID User-ID and GlobalProtect.
• Enterprise Wireless: (Juniper Mist & Aruba) Mist Cloud Aruba AirWave/Conductor ClearPass/RADIUS integration dynamic packet captures and high-density 802.1X designs.
• High-Touch Cross-Functional Communication: Exceptional ability to translate non-standard business and physical engineering requirements into pragmatic resilient network architectures.
• Operational Excellence: Willingness to support a weekly Tier-3 on-call rotation and travel periodically to remote field sites test facilities or manufacturing sites when hands-on senior engineering is required.
• Eligible to obtain and maintain an active U.S. Secret security clearance

• Senior or Expert-level industry certifications (CCNP/CCIE JNCIP/JNCIE PCNSE or Arista ACE).
• Certifications in public cloud networking (e.g. AWS Certified Advanced Networking - Specialty Azure Network Engineer Associate).
• Experience operating within regulated or compliance-driven environments (e.g. ITAR EAR NIST 800-171 CMMC).
• Experience with Network Source-of-Truth platforms (NetBox Nautobot).
• Hands-on experience with modern observability platforms (Telegraf InfluxDB Prometheus Grafana OpenConfig/gNMI).
